- the various embodiments are useful in an on-demand multi-tenant database and/or application service or any system or systems in which electronic documents are shared or exchanged.
- multi-tenant database system refers to those systems in which various elements of hardware and software of the database system may be shared by one or more customers.
- a given application server e.g. running an application process
- a given database table may store rows for a potentially much greater number of customers.
- FIG. 1 illustrates a block diagram of an environment 10 wherein an on-demand database service might be used.
- Environment 10 may include user systems 12 , network 14 , system 16 , processor system 17 , application platform 18 , network interface 20 , tenant data storage 22 , system data storage 24 , program code 26 , and process space 28 .
- environment 10 may not have all of the components listed and/or may have other elements instead of, or in addition to, those listed above.
- Environment 10 is an environment in which an on-demand database service exists.
- User system 12 may be any machine or system that is used by a user to access a database user system.
- any of user systems 12 can be a handheld computing device, a mobile phone, a laptop computer, a work station, and/or a network of computing devices.
- user systems 12 might interact via a network 14 with an on-demand database service, which is system 16 .
- An on-demand database service such as system 16
- system 16 is a database system that is made available to outside users that do not need to necessarily be concerned with building and/or maintaining the database system, but instead may be available for their use when the users need the database system (e.g., on the demand of the users).
- Some on-demand database services may store information from one or more tenants stored into tables of a common database image to form a multi-tenant database system (MTS).
- MTS multi-tenant database system
- “on-demand database service 16 ” and “system 16 ” will be used interchangeably herein.
- a database image may include one or more database objects.
- Application platform 18 may be a framework that allows the applications of system 16 to run, such as the hardware and/or software, e.g., the operating system.
- on-demand database service 16 may include an application platform 18 that enables creation, managing and executing one or more applications developed by the provider of the on-demand database service, users accessing the on-demand database service via user systems 12 , or third party application developers accessing the on-demand database service via user systems 12 .
- the users of user systems 12 may differ in their respective capacities, and the capacity of a particular user system 12 might be entirely determined by permissions (permission levels) for the current user. For example, where a salesperson is using a particular user system 12 to interact with system 16 , that user system has the capacities allotted to that salesperson. However, while an administrator is using that user system to interact with system 16 , that user system has the capacities allotted to that administrator.
- users at one permission level may have access to applications, data, and database information accessible by a lower permission level user, but may not have access to certain applications, database information, and data accessible by a user at a higher permission level. Thus, different users will have different capabilities with regard to accessing and modifying application and database information, depending on a user's security or permission level.
- Network 14 is any network or combination of networks of devices that communicate with one another.
- network 14 can be any one or any combination of a LAN (local area network), WAN (wide area network), telephone network, wireless network, point-to-point network, star network, token ring network, hub network, or other appropriate configuration.

- HTTP HyperText Transfer Protocol
- user system 12 might include an HTTP client commonly referred to as a “browser” for sending and receiving HTTP messages to and from an HTTP server at system 16 .
- HTTP server might be implemented as the sole network interface between system 16 and network 14 , but other techniques might be used as well or instead.
- the interface between system 16 and network 14 includes load sharing functionality, such as round-robin HTTP request distributors to balance loads and distribute incoming HTTP requests evenly over a plurality of servers. At least as for the users that are accessing that server, each of the plurality of servers has access to the MTS' data; however, other alternative configurations may be used instead.
- system 16 implements a web-based customer relationship management (CRM) system.
- system 16 includes application servers configured to implement and execute CRM software applications (application processes) as well as provide related data, code, forms, web pages and other information to and from user systems 12 and to store to, and retrieve from, a database system related data, objects, and Webpage content.
- CRM software applications application processes
- data for multiple tenants may be stored in the same physical database object, however, tenant data typically is arranged so that data of one tenant is kept logically separate from that of other tenants so that one tenant does not have access to another tenant's data, unless such data is expressly shared.
- system 16 implements applications other than, or in addition to, a CRM application.
- system 16 may provide tenant access to multiple hosted (standard and custom) applications, including a CRM application.
- User (or third party developer) applications which may or may not include CRM, may be supported by the application platform 18 , which manages creation, storage of the applications into one or more database objects and executing of the applications in a virtual machine in the process space of the system 16 .

- another application server 100 N might be coupled by yet a different network connection.
- Transfer Control Protocol and Internet Protocol TCP/IP are typical protocols for communicating between application servers 100 and the database system.
- TCP/IP Transfer Control Protocol and Internet Protocol
- each application server 100 is configured to handle requests for any user associated with any organization that is a tenant. Because it is desirable to be able to add and remove application servers from the server pool at any time for any reason, there is preferably no server affinity for a user and/or organization to a specific application server 100 .
- an interface system implementing a load balancing function e.g., an F5 Big-IP load balancer
- the load balancer uses a least connections algorithm to route user requests to the application servers 100 .
- Other examples of load balancing algorithms such as round robin and observed response time, also can be used.
- system 16 is multi-tenant, wherein system 16 handles storage of, and access to, different objects, data and applications across disparate users and organizations.
- one tenant might be a company that employs a sales force where each salesperson uses system 16 to manage their sales process.
- a user might maintain contact data, leads data, customer follow-up data, performance data, goals and progress data, etc., all applicable to that user's personal sales process (e.g., in tenant data storage 22 ).
- tenant data storage 22 e.g., in tenant data storage 22 .
- the user can manage his or her sales efforts and cycles from any of many different user systems. For example, if a salesperson is visiting a customer and the customer has Internet access in their lobby, the salesperson can obtain critical updates as to that customer while waiting for the customer to arrive in the lobby.
- user systems 12 (which may be client systems) communicate with application servers 100 to request and update system-level and tenant-level data from system 16 that may require sending one or more queries to tenant data storage 22 and/or system data storage 24 .
- System 16 e.g., an application server 100 in system 16
- System data storage 24 may generate query plans to access the requested data from the database.
- a table generally contains one or more data categories logically arranged as columns or fields in a viewable schema. Each row or record of a table contains an instance of data for each category defined by the fields.
- a CRM database may include a table that describes a customer with fields for basic contact information such as name, address, phone number, fax number, etc.
- Another table might describe a purchase order, including fields for information such as customer, product, sale price, date, etc.
- Yet another table or object might describe an Opportunity, including fields such as organization, period, forecast type, user, territory, etc.
- tenants may be allowed to create and store custom objects, or they may be allowed to customize standard entities or objects, for example by creating custom fields for standard objects, including custom index fields.
- U.S. patent application Ser. No. 10/817,161, filed Apr. 2, 2004, entitled “Custom Entities and Fields in a Multi-Tenant Database System”, and which is hereby incorporated herein by reference, teaches systems and methods for creating custom objects as well as customizing standard objects in a multi-tenant database system.
- a system works across any document type by providing visual overlays on top of a document without modifying the original document.
- Multiple, alternative annotations can exist together or independently.
- any drawing on an overlay can be immediately shared with other users. Since overlays are transparent, multiple overlays may be shown at the same time. These overlays could be from one or more users. If multiple overlays are created, a display order is maintained in one embodiment. Initially, this can be the order in which they were created, but it is possible to override this default manually. By maintaining an overlay order it is possible to annotate an existing overlay.
- FIG. 3 illustrates a method 300 of creating and sharing document annotations according to one embodiment.
- a document is created or accessed or retrieved and displayed on a graphical user interface.
- a user may create a document to be shared for collaboration using any of a variety of document creation applications, or the user may retrieve a document from storage, or a user may receive a document from another user or source.
- Examples of document types include text-based documents, image-based documents, video-based documents, or any other document type viewable on a graphical user interface. Specific examples include Word documents, PowerPoint documents, Visio document, Flash-based images or videos, and Excel spreadsheets, however one skilled in the art will understand that any document type may be created or accessed using any document creation or editing application.
- a document overlay window is displayed over the document, for example in response to a user request to provide annotations to the displayed document.
- the user request may be by way of accessing a specific application (e.g., a stand-alone application) designed to generate the document overlay, or using functionality included and integrated with a document editing tool.
- document annotations are input by a user using a user input device, and the annotations are displayed in the overlay window in step 340 .
- FIG. 4 a illustrates a graphical user interface display 400 including a document 410 displayed therein. As shown, the document 410 represents a text based (e.g., a Word document).
- FIG. 4 b illustrates an overlay window 420 displayed over document 410 in display 400 .
- the overlay window 420 includes annotations provided by a user; specifically the annotations shown include two handwritten “circle” marks and some text: “xxxxx”, as input by the user.
- the boundary of the overlay window is larger than the document, however, the boundary may be configurable such that the user can make the boundary smaller or larger than the document, e.g., by selecting an icon on or by the overlay and adjusting the size/dimensions thereby.
- FIGS. 6 and 7 show example of smaller overlays displayed over a document. Also, controls are provided to a user to change the positioning of the displayed overlay relative to the document, e.g., by selecting the overlay and dragging to a new position.
- User input may include handwritten or typed text, or pasting of documents, icons or images selected from the user's system.
- an overlay includes a transparent work area which aligns with the document, a border indicator to show the bounds of the overlay, and overlay controls.
- the overlay window within the border indicator is transparent, in certain aspects, to allow unfettered viewing of the document contents.
- the user can use standard controls to create annotations, e.g., by drawing or typing on top of an overlay, using any user input device, such as a mouse, keyboard, pen or stylus, touch-screen or touch pad, etc. The user's input will appear as if it is located (e.g., written) on top of the underlying document.
- drawing controls include lines, standard shapes, useful icons, text and images.
- annotation information is stored to the system, e.g., local system memory, or persisted to a remote memory such as a database system or application server.
- the stored information includes the annotations provided by the user as well as positioning information such as the position(s) of annotations within the overlay window, and positioning information of the overlay window relative to the document.
- positioning information might include the document size/resolution, the document zoom, and the document position. Using this information an overlay can be scaled for a different interface such that it closely matches its original position relative to the document on a different interface.
- the annotation information is shared with another user.
- the user that creates the annotations allows access to the annotations to a second user.
- this includes sending the annotation information to the second user (e.g., the second user's computer system) by way of a network connection, such as a VPN, WAN, LAN, Internet, etc.
- this includes enabling the second user to retrieve the annotation information, e.g., from memory or a server system, such as by sending a link to the annotation information, or otherwise alerting the second user that the annotation information may be accessed.
- the document may also be sent with, or retrieved with, the annotation information. For example, if the second user already has access to the document, only the annotation information need be enabled for access. This may occur where the second user is the creator of the document, or where the second user may have already accessed the document and asked the first user for comments/annotations.
- the annotation information accessed or received by the second user is used to generate an overlay on the document on the second users system.
- the overlay window is displayed with the first user's annotations on the second user's graphical user interface, the second user is able to see the annotations overlaying the document.
- FIG. 5 a illustrates a graphical user interface display 500 on the second user's system where the resolution is the same as on the first user's system, e.g., overlay window 420 is displayed over document 410 in the same resolution as shown in FIG. 4 b .
- FIG. 5 b illustrates a situation where the second user's system has a different resolution and/or aspect ratio than the first user's system.
- the graphical user interface 550 (with a different aspect ratio for example), includes the displayed document (now 560 to indicate a different document aspect ratio or size).
- the positioning information associated with the overlay is used to appropriately scale the overlay 570 so that the sizing and positions of the displayed annotations relative to the document contents closely match that in the original system.
- FIG. 6 illustrates an example of an overlay floating over a document. As shown annotations by a user are displayed in the overlay over the document (underlined “the” and an arrow pointing to Sample 2 ).
- the first user may create a second overlay for the document 410 and allow access to the second user.
- the second user may access and display the second overlay over the document in addition to the first overlay, or as a replacement for the first overlay.
- a third user may create a separate overlay for the document and allow access to other users, including the second user.
- the second user may access and display the third user's overlay (and annotations) over the document in addition to the first user's overlay, or as a replacement for the first user's overlay.
- a visual indicator may be displayed to indicate the number of available overlays for the document and/or to allow the viewing user to select from among the available overlays.
- the viewing user may select one, more than one, or all of the available overlays to be simultaneously displayed over the document being viewed.
- the overlays may be color-coded according to creating user, or otherwise distinguished based on user.
- FIG. 7 illustrates two different overlays displayed over a document. As shown, overlay 1 is positioned over a different portion of the document than overlay 2 . In the situation where overlay 1 and overlay 2 were created by different users, they may be displayed in different colors or shadings to help the viewing user distinguish the source. Alternatively or additionally, a user indicator such as an icon or text can be displayed with the overlay to identify the source.
- overlays can be shared in real-time, or in near real time, as the overlay is being created.
- annotations being input by a user on one system can be transmitted to systems of other users partaking in the collaborative effort as the annotations are being created, or just after the annotations have been created (and the creating user indicates acceptance, for example).
- a user is able to integrate annotations provided in an overlay into the underlying document. For example, a user may be able select or indicate 0, 1, or a number of the overlays and flatten or permanently integrate them into the underlying document. In FIG. 3 this is represented as step 380 , where the selected overlays are considered to be ‘approved’ and therefore are incorporated into the final document.
- various overlay controls are provided for use by a user.
- useful overlay controls include controls to create a new overlay, to save or delete an overlay, to control display parameters of an overlay.
- one or more of the following user controls are provided:
- This control allows a user to save an overlay or a set of overlays, along with information relevant to the overlays and the documents (e.g., overlay size/resolution, document name, document page(s), document zoom, display order, etc.)
- Overlay notes This control allows a user to add additional notes to an overlay which do not actually appear on the overlay (these notes are not annotations of the document).
- One purpose of these notes may be to provide context or background information.
- Overlay display control This control allows a user to display an individual overlay or sets of overlays. If sets of overlays are shown, the display order is respected, by default.
- Overlay default color control To help with discrimination when multiple overlays are shown, this control allows a user to set the default color for an overlay. For instance, different users could use different colors, making it possible, even when all overlays are shown, to determine who specified what.
- a tool to ‘hide’ sections of the underlying document is provided. While this will not actually delete material from the underlying document (nor cause it to reflow), it will hide that section while the overlay is displayed.
- the position information includes a percentage of the current screen resolution. For example, if the vertical position is indicated as extending from 20% to 80% from the top to the bottom of the document (and similarly the horizontal position as extending from x % to y % from left to right) this can be used to scale the overlay over a different resolution. The pixel count can change between documents, but the percentage would remain the same.
Abstract
Systems and methods for sharing document annotations. A document is displayed on a graphical user interface and first annotation information for the document is created by a first user, the annotation information including first annotations and positioning information for positioning a first overlay window relative to the document. The first overlay window with the first annotations is displayed over the document wherein the document is visible through the first overlay window. The annotation information is sharable with other users, whereby a different user is able to display the overlay with annotations made by the first user over the document on a different system, and the annotations do not modify the underlying document.
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 61/346,844, filed May 20, 2010, the disclosure of which is incorporated herein by reference in its entirety.
- A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
- The present generally relates to sharing documents, and more particularly to sharing one or multiple graphical annotations of a document using overlays.
- Often when collaborating on a document there is a desire to annotate the document and consider a variety of information and approaches. For many document types, certain annotation tools already exist (for instance, change tracking in MS Word, or comment balloons in PDF files). These tools either support the direct manipulation of the document or allow users to annotate the documents, share the annotations and eventually coalesce the annotations into one and only one set. It can be cumbersome, however, using existing technologies to remove changes that are part of the document and/or wade through the various changes or comments made by various users when multiple users are commenting on, or modifying a document
- There is therefore a need for improved systems and methods that overcome the above problems and that provide improved document collaboration capabilities.
- The present invention generally relates to document sharing and collaboration, and more particularly to providing graphical annotations of documents using overlays. The techniques are applicable for use in an on-demand database and/or application service or any environment or environments in which electronic documents are shared or exchanged.
- According to one embodiment, a computer-implemented method is provided for sharing document annotations. The method typically includes displaying a document on a first graphical user interface, displaying a document overlay window over the document, wherein the document is visible through the overlay window, and receiving annotations from a first user via a user-input device. The input device may include a mouse or keyboard, or a touch screen (e.g., user gestures on a touch-screen, such as a tablet computer, touch-screen peripheral, iPad, or mobile cell phone device such as a Blackberry or an iPhone). The method also typically includes displaying the annotations in the overlay window, storing annotation information, the annotation information including the annotations and positioning information for the overlay window relative to the document, and allowing access to the document and the annotation information to a second user. The method further typically includes displaying the document and the overlay window with the annotations on a second graphical user interface, whereby the second user is able to see the annotations overlaying the document when the overlay window is displayed on the second graphical user interface. In certain aspects, allowing access to the document and the annotation information includes either a) sending to the second user the annotation information and the document, or b) storing the annotation information and the document to a server system, whereby the second user retrieves the stored annotation information and the document from the server system. In certain aspects, the positioning information is used to facilitate the alignment of the overlay on devices or systems having a different or alternate resolution interfaces. In certain aspects, the first graphical user interface has a first resolution and the second graphical user interface has a second resolution different than the first resolution, wherein displaying the document and the overlay window with the annotations on the second graphical user interface includes scaling the size of the displayed overlay window and annotations to match the second resolution based on the annotation information.
- According to another embodiment, a computer-implemented method is provided for sharing document annotations. The method typically includes displaying a document on a graphical user interface, receiving first annotation information for the document created by a first user, the annotation information including first annotations and positioning information for positioning a first overlay window relative to the document; and displaying the first overlay window with the first annotations over the document wherein the document is visible through the first overlay window.
- According to yet another embodiment, a tangible computer-readable medium is provided that stores code which, when executed by one or more processors, causes the processor(s) to display a document on a graphical user interface, to receive first annotation information for the document created by a first user, the annotation information including first annotations and positioning information for positioning a first overlay window relative to the document, and to display the first overlay window with the first annotations over the document wherein the document is visible through the first overlay window.
- According to still another embodiment, a tangible computer-readable medium is provided that stores code for enabling sharing of document annotations. The code typically includes instructions that when executed by one or more processor cause the processor(s) to display a document on a first graphical user interface, to display a document overlay window over the document, wherein the document is visible through the overlay window, and to receive annotations from a first user via a user-input device. The code also typically includes instructions to display the annotations in the overlay window, to store annotation information, the annotation information including the annotations and positioning information for the overlay window relative to the document, and to allow access to the document and the annotation information to a second user. The code further typically includes instructions to display the document and the overlay window with the annotations on a second graphical user interface, whereby the second user is able to see the annotations overlaying the document when the overlay window is displayed on the second graphical user interface. In certain aspects, the code to allow access includes either: a) code to send to the second user the annotation information and the document, or b) code to enable the second user to retrieve the annotation information and the document from a server system.
- According to yet a further embodiment, a document sharing system is provided that typically includes a display device for displaying a graphical user interface, and a processor configured to display a document on the graphical user interface, to receive first annotation information for the document created by a first user, the annotation information including first annotations and positioning information for positioning a first overlay window relative to the document, and to display the first overlay window with the first annotations over the document wherein the document is visible through the first overlay window.
- According to still a further embodiment, a document sharing system is provided that typically includes a first computer system having a display device for displaying a first graphical user interface, and a first processor configured to display a document on the graphical user interface, to display a document overlay window over the document, wherein the document is visible through the overlay window, to receive annotations from a first user via a user-input device, and to display the annotations in the overlay window. The first processor is also typically configured to store annotation information, the annotation information including the annotations and positioning information for the overlay window relative to the document, and to allow access to the document and the annotation information to a second user. The system also typically includes a second computer system, communicably coupled with the first computer system over a network, the second computer system having a display device for displaying a second graphical user interface, and a second processor configured to display the document and the overlay window with the annotations on the second graphical user interface, whereby the second user is able to see the annotations overlaying the document when the overlay window is displayed on the second graphical user interface. In certain aspects, the first processor allows access to the document and the annotation information by a) sending to the second computer system the annotation information and the document, or b) storing the annotation information and the document to a server system, whereby the second computer system retrieves the stored annotation information and the document from the server system.

The various embodiments are useful in an on-demand multi-tenant database and/or application service or any system or systems in which electronic documents are shared or exchanged.
- As used herein, the term multi-tenant database system refers to those systems in which various elements of hardware and software of the database system may be shared by one or more customers. For example, a given application server (e.g. running an application process) may simultaneously process requests for a great number of customers, and a given database table may store rows for a potentially much greater number of customers.
-
FIG. 1 illustrates a block diagram of anenvironment 10 wherein an on-demand database service might be used.Environment 10 may includeuser systems 12,network 14,system 16,processor system 17,application platform 18,network interface 20,tenant data storage 22,system data storage 24,program code 26, andprocess space 28. In other embodiments,environment 10 may not have all of the components listed and/or may have other elements instead of, or in addition to, those listed above. -
Environment 10 is an environment in which an on-demand database service exists.User system 12 may be any machine or system that is used by a user to access a database user system. For example, any ofuser systems 12 can be a handheld computing device, a mobile phone, a laptop computer, a work station, and/or a network of computing devices. As illustrated inFIG. 1 (and in more detail inFIG. 2 )user systems 12 might interact via anetwork 14 with an on-demand database service, which issystem 16. - An on-demand database service, such as
system 16, is a database system that is made available to outside users that do not need to necessarily be concerned with building and/or maintaining the database system, but instead may be available for their use when the users need the database system (e.g., on the demand of the users). Some on-demand database services may store information from one or more tenants stored into tables of a common database image to form a multi-tenant database system (MTS). Accordingly, “on-demand database service 16” and “system 16” will be used interchangeably herein. A database image may include one or more database objects. A relational database management system (RDMS) or the equivalent may execute storage and retrieval of information against the database object(s).Application platform 18 may be a framework that allows the applications ofsystem 16 to run, such as the hardware and/or software, e.g., the operating system. In an embodiment, on-demand database service 16 may include anapplication platform 18 that enables creation, managing and executing one or more applications developed by the provider of the on-demand database service, users accessing the on-demand database service viauser systems 12, or third party application developers accessing the on-demand database service viauser systems 12. - The users of
user systems 12 may differ in their respective capacities, and the capacity of aparticular user system 12 might be entirely determined by permissions (permission levels) for the current user. For example, where a salesperson is using aparticular user system 12 to interact withsystem 16, that user system has the capacities allotted to that salesperson. However, while an administrator is using that user system to interact withsystem 16, that user system has the capacities allotted to that administrator. In systems with a hierarchical role model, users at one permission level may have access to applications, data, and database information accessible by a lower permission level user, but may not have access to certain applications, database information, and data accessible by a user at a higher permission level. Thus, different users will have different capabilities with regard to accessing and modifying application and database information, depending on a user's security or permission level. -
Network 14 is any network or combination of networks of devices that communicate with one another. For example,network 14 can be any one or any combination of a LAN (local area network), WAN (wide area network), telephone network, wireless network, point-to-point network, star network, token ring network, hub network, or other appropriate configuration. As the most common type of computer network in current use is a TCP/IP (Transfer Control Protocol and Internet Protocol) network, such as the global internetwork of networks often referred to as the “Internet” with a capital “I,” that network will be used in many of the examples herein. However, it should be understood that the networks that the present invention might use are not so limited, although TCP/IP is a frequently implemented protocol. -
User systems 12 might communicate withsystem 16 using TCP/IP and, at a higher network level, use other common Internet protocols to communicate, such as HTTP, FTP, AFS, WAP, etc. In an example where HTTP is used,user system 12 might include an HTTP client commonly referred to as a “browser” for sending and receiving HTTP messages to and from an HTTP server atsystem 16. Such an HTTP server might be implemented as the sole network interface betweensystem 16 andnetwork 14, but other techniques might be used as well or instead. In some implementations, the interface betweensystem 16 andnetwork 14 includes load sharing functionality, such as round-robin HTTP request distributors to balance loads and distribute incoming HTTP requests evenly over a plurality of servers. At least as for the users that are accessing that server, each of the plurality of servers has access to the MTS' data; however, other alternative configurations may be used instead. - In one embodiment,
system 16, shown inFIG. 1 , implements a web-based customer relationship management (CRM) system. For example, in one embodiment,system 16 includes application servers configured to implement and execute CRM software applications (application processes) as well as provide related data, code, forms, web pages and other information to and fromuser systems 12 and to store to, and retrieve from, a database system related data, objects, and Webpage content. With a multi-tenant system, data for multiple tenants may be stored in the same physical database object, however, tenant data typically is arranged so that data of one tenant is kept logically separate from that of other tenants so that one tenant does not have access to another tenant's data, unless such data is expressly shared. In certain embodiments,system 16 implements applications other than, or in addition to, a CRM application. For example,system 16 may provide tenant access to multiple hosted (standard and custom) applications, including a CRM application. User (or third party developer) applications, which may or may not include CRM, may be supported by theapplication platform 18, which manages creation, storage of the applications into one or more database objects and executing of the applications in a virtual machine in the process space of thesystem 16. - One arrangement for elements of
system 16 is shown inFIG. 1 , including anetwork interface 20,application platform 18,tenant data storage 22 fortenant data 23,system data storage 24 forsystem data 25 accessible tosystem 16 and possibly multiple tenants,program code 26 for implementing various functions ofsystem 16, and aprocess space 28 for executing MTS system processes and tenant-specific processes, such as running applications as part of an application hosting service. Additional processes that may execute onsystem 16 include database indexing processes. - Several elements in the system shown in
FIG. 1 include conventional, well-known elements that are explained only briefly here. For example, eachuser system 12 could include a desktop personal computer, workstation, laptop, PDA, cell phone, or any wireless access protocol (WAP) enabled device or any other computing device capable of interfacing directly or indirectly to the Internet or other network connection.User system 12 typically runs an HTTP client, e.g., a browsing program, such as Microsoft's Internet Explorer browser, Netscape's Navigator browser, Opera's browser, or a WAP-enabled browser in the case of a cell phone, PDA or other wireless device, or the like, allowing a user (e.g., subscriber of the multi-tenant database system) ofuser system 12 to access, process and view information, pages and applications available to it fromsystem 16 overnetwork 14. Eachuser system 12 also typically includes one or more user interface devices, such as a keyboard, a mouse, trackball, touch pad, touch screen, pen or the like, for interacting with a graphical user interface (GUI) provided by the browser on a display (e.g., a monitor screen, LCD display, etc.) in conjunction with pages, forms, applications and other information provided bysystem 16 or other systems or servers. For example, the user interface device can be used to access data and applications hosted bysystem 16, such as documents and annotation overlays as discussed below, and to perform searches on stored data, and otherwise allow a user to interact with various GUI pages that may be presented to a user. As discussed above, embodiments are suitable for use with the Internet, which refers to a specific global internetwork of networks. However, it should be understood that other networks can be used instead of the Internet, such as an intranet, an extranet, a virtual private network (VPN), a non-TCP/IP based network, any LAN or WAN or the like. - According to one embodiment, each
user system 12 and all of its components are operator configurable using applications (such as a browser application, a document viewer or editing application, etc.) including computer code run using a central processing unit such as an Intel Pentium® processor or the like. Similarly, system 16 (and additional instances of an MTS, where more than one is present) and all of their components might be operator configurable using application(s) including computer code to run using a central processing unit such asprocessor system 17, which may include an Intel Pentium® processor or the like, and/or multiple processor units. A computer program product embodiment includes a machine-readable storage medium (media) having instructions stored thereon/in which can be used to program a computer to perform any of the processes of the embodiments described herein. Computer code for operating and configuringsystem 16 to intercommunicate and to process web pages, applications and other data and media content as described herein are preferably downloaded and stored on a hard disk, but the entire program code, or portions thereof, may also be stored in any other volatile or non-volatile memory medium or device as is well known, such as a ROM or RAM, or provided on any media capable of storing program code, such as any type of rotating media including floppy disks, optical discs, digital versatile disk (DVD), compact disk (CD), microdrive, and magneto-optical disks, and magnetic or optical cards, nanosystems (including molecular memory ICs), or any type of media or device suitable for storing instructions and/or data. Additionally, the entire program code, or portions thereof, may be transmitted and downloaded from a software source over a transmission medium, e.g., over the Internet, or from another server, as is well known, or transmitted over any other conventional network connection as is well known (e.g., extranet, VPN, LAN, etc.) using any communication medium and protocols (e.g., TCP/IP, HTTP, HTTPS, Ethernet, etc.) as are well known. It will also be appreciated that computer code for implementing embodiments of the present invention can be implemented in any programming language that can be executed on a client system and/or server or server system such as, for example, C, C++, HTML, any other markup language, Java™, JavaScript, ActiveX, any other scripting language, such as VBScript, and many other programming languages as are well known may be used. (Java™ is a trademark of Sun Microsystems, Inc.). - According to one embodiment, each
system 16 is configured to provide web pages, forms, applications, data and media content to user (client)systems 12 to support the access byuser systems 12 as tenants ofsystem 16. As such,system 16 provides security mechanisms to keep each tenant's data separate unless the data is shared. If more than one MTS is used, they may be located in close proximity to one another (e.g., in a server farm located in a single building or campus), or they may be distributed at locations remote from one another (e.g., one or more servers located in city A and one or more servers located in city B). As used herein, each MTS could include one or more logically and/or physically connected servers distributed locally or across one or more geographic locations. Additionally, the term “server” is meant to include a computer system, including processing hardware and process space(s), and an associated storage system and database application (e.g., OODBMS or RDBMS) as is well known in the art. It should also be understood that “server system” and “server” are often used interchangeably herein. Similarly, the database object described herein can be implemented as single databases, a distributed database, a collection of distributed databases, a database with redundant online or offline backups or other redundancies, etc., and might include a distributed database or storage network and associated processing intelligence. -
FIG. 2 also illustratesenvironment 10. However, inFIG. 2 elements ofsystem 16 and various interconnections in an embodiment are further illustrated.FIG. 2 shows thatuser system 12 may includeprocessor system 12A,memory system 12B,input system 12C, andoutput system 12D.FIG. 2 showsnetwork 14 andsystem 16.FIG. 2 also shows thatsystem 16 may includetenant data storage 22,tenant data 23,system data storage 24,system data 25, User Interface (UI) 30, Application Program Interface (API) 32, PL/SOQL 34, saveroutines 36,application setup mechanism 38, applications servers 100 1-100 N,system process space 102,tenant process spaces 104, tenantmanagement process space 110,tenant storage area 112,user storage 114, andapplication metadata 116. In other embodiments,environment 10 may not have the same elements as those listed above and/or may have other elements instead of, or in addition to, those listed above. -
User system 12,network 14,system 16,tenant data storage 22, andsystem data storage 24 were discussed above inFIG. 1 . Regardinguser system 12,processor system 12A may be any combination of one or more processors.Memory system 12B may be any combination of one or more memory devices, short term, and/or long term memory.Input system 12C may be any combination of input devices, such as one or more keyboards, mice, trackballs, scanners, cameras, and/or interfaces to networks.Output system 12D may be any combination of output devices, such as one or more monitors, printers, and/or interfaces to networks. As shown byFIG. 2 ,system 16 may include a network interface 20 (ofFIG. 1 ) implemented as a set of HTTP application servers 100, anapplication platform 18,tenant data storage 22, andsystem data storage 24. Also shown issystem process space 102, including individualtenant process spaces 104 and a tenantmanagement process space 110. Each application server 100 may be configured to tenantdata storage 22 and thetenant data 23 therein, andsystem data storage 24 and thesystem data 25 therein to serve requests ofuser systems 12. Thetenant data 23 might be divided into individualtenant storage areas 112, which can be either a physical arrangement and/or a logical arrangement of data. Within eachtenant storage area 112,user storage 114 andapplication metadata 116 might be similarly allocated for each user. For example, a copy of a user's most recently used (MRU) items might be stored touser storage 114. Similarly, a copy of MRU items for an entire organization that is a tenant might be stored to tenantstorage area 112. AUI 30 provides a user interface and anAPI 32 provides an application programmer interface tosystem 16 resident processes to users and/or developers atuser systems 12. The tenant data and the system data may be stored in various databases, such as one or more Oracle™ databases. -
Application platform 18 includes anapplication setup mechanism 38 that supports application developers' creation and management of applications, which may be saved as metadata intotenant data storage 22 by saveroutines 36 for execution by subscribers as one or moretenant process spaces 104 managed bytenant management process 110 for example. Invocations to such applications may be coded using PL/SOQL 34 that provides a programming language style interface extension toAPI 32. A detailed description of some PL/SOQL language embodiments is discussed in commonly owned co-pending U.S. Provisional Patent Application 60/828,192 entitled, PROGRAMMING LANGUAGE METHOD AND SYSTEM FOR EXTENDING APIS TO EXECUTE IN CONJUNCTION WITH DATABASE APIS, by Craig Weissman, filed Oct. 4, 2006, which is incorporated in its entirety herein for all purposes. Invocations to applications may be detected by one or more system processes, which manages retrievingapplication metadata 116 for the subscriber making the invocation and executing the metadata as an application in a virtual machine. - Each application server 100 may be communicably coupled to database systems, e.g., having access to
system data 25 andtenant data 23, via a different network connection. For example, one application server 100 1 might be coupled via the network 14 (e.g., the Internet), another application server 100 N-1 might be coupled via a direct network link, and another application server 100 N might be coupled by yet a different network connection. Transfer Control Protocol and Internet Protocol (TCP/IP) are typical protocols for communicating between application servers 100 and the database system. However, it will be apparent to one skilled in the art that other transport protocols may be used to optimize the system depending on the network interconnect used. - In certain embodiments, each application server 100 is configured to handle requests for any user associated with any organization that is a tenant. Because it is desirable to be able to add and remove application servers from the server pool at any time for any reason, there is preferably no server affinity for a user and/or organization to a specific application server 100. In one embodiment, therefore, an interface system implementing a load balancing function (e.g., an F5 Big-IP load balancer) is communicably coupled between the application servers 100 and the
user systems 12 to distribute requests to the application servers 100. In one embodiment, the load balancer uses a least connections algorithm to route user requests to the application servers 100. Other examples of load balancing algorithms, such as round robin and observed response time, also can be used. For example, in certain embodiments, three consecutive requests from the same user could hit three different application servers 100, and three requests from different users could hit the same application server 100. In this manner,system 16 is multi-tenant, whereinsystem 16 handles storage of, and access to, different objects, data and applications across disparate users and organizations. - As an example of storage, one tenant might be a company that employs a sales force where each salesperson uses
system 16 to manage their sales process. Thus, a user might maintain contact data, leads data, customer follow-up data, performance data, goals and progress data, etc., all applicable to that user's personal sales process (e.g., in tenant data storage 22). In an example of a MTS arrangement, since all of the data and the applications to access, view, modify, report, transmit, calculate, etc., can be maintained and accessed by a user system having nothing more than network access, the user can manage his or her sales efforts and cycles from any of many different user systems. For example, if a salesperson is visiting a customer and the customer has Internet access in their lobby, the salesperson can obtain critical updates as to that customer while waiting for the customer to arrive in the lobby. - While each user's data might be separate from other users' data regardless of the employers of each user, some data might be organization-wide data shared or accessible by a plurality of users or all of the users for a given organization that is a tenant. Thus, there might be some data structures managed by
system 16 that are allocated at the tenant level while other data structures might be managed at the user level. Because an MTS might support multiple tenants including possible competitors, the MTS should have security protocols that keep data, applications, and application use separate. Also, because many tenants may opt for access to an MTS rather than maintain their own system, redundancy, up-time, and backup are additional functions that may be implemented in the MTS. In addition to user-specific data and tenant-specific data,system 16 might also maintain system level data usable by multiple tenants or other data. Such system level data might include industry reports, news, postings, and the like that are sharable among tenants. - In certain embodiments, user systems 12 (which may be client systems) communicate with application servers 100 to request and update system-level and tenant-level data from
system 16 that may require sending one or more queries to tenantdata storage 22 and/orsystem data storage 24. System 16 (e.g., an application server 100 in system 16) automatically generates one or more SQL statements (e.g., one or more SQL queries) that are designed to access the desired information.System data storage 24 may generate query plans to access the requested data from the database. - A table generally contains one or more data categories logically arranged as columns or fields in a viewable schema. Each row or record of a table contains an instance of data for each category defined by the fields. For example, a CRM database may include a table that describes a customer with fields for basic contact information such as name, address, phone number, fax number, etc. Another table might describe a purchase order, including fields for information such as customer, product, sale price, date, etc. Yet another table or object might describe an Opportunity, including fields such as organization, period, forecast type, user, territory, etc.
- In some multi-tenant database systems, tenants may be allowed to create and store custom objects, or they may be allowed to customize standard entities or objects, for example by creating custom fields for standard objects, including custom index fields. U.S. patent application Ser. No. 10/817,161, filed Apr. 2, 2004, entitled “Custom Entities and Fields in a Multi-Tenant Database System”, and which is hereby incorporated herein by reference, teaches systems and methods for creating custom objects as well as customizing standard objects in a multi-tenant database system.
- Often when collaborating on a document there is a desire to annotate the document and consider a variety of information and approaches. This is true whether the document under discussion is primarily text, image, graphical design, video or some other document type. The collaboration can include a single user or multiple users proposing changes or modifications either offline, or in a live, online setting. For most specific document types, certain annotation tools already exist (for instance, change tracking in MS Word, or comment balloons in PDF files). These tools either support the direct manipulation of the document or allow users to annotate the documents, share the annotations and eventually coalesce the annotations into one and only one set.
- According to one embodiment, a system is provided that works across any document type by providing visual overlays on top of a document without modifying the original document. Multiple, alternative annotations can exist together or independently.
- In an interactive online environment, any drawing on an overlay can be immediately shared with other users. Since overlays are transparent, multiple overlays may be shown at the same time. These overlays could be from one or more users. If multiple overlays are created, a display order is maintained in one embodiment. Initially, this can be the order in which they were created, but it is possible to override this default manually. By maintaining an overlay order it is possible to annotate an existing overlay.

FIG. 3 illustrates amethod 300 of creating and sharing document annotations according to one embodiment. Instep 310, a document is created or accessed or retrieved and displayed on a graphical user interface. For example, a user may create a document to be shared for collaboration using any of a variety of document creation applications, or the user may retrieve a document from storage, or a user may receive a document from another user or source. Examples of document types include text-based documents, image-based documents, video-based documents, or any other document type viewable on a graphical user interface. Specific examples include Word documents, PowerPoint documents, Visio document, Flash-based images or videos, and Excel spreadsheets, however one skilled in the art will understand that any document type may be created or accessed using any document creation or editing application. - In
step 320, a document overlay window is displayed over the document, for example in response to a user request to provide annotations to the displayed document. The user request may be by way of accessing a specific application (e.g., a stand-alone application) designed to generate the document overlay, or using functionality included and integrated with a document editing tool. Instep 330, document annotations are input by a user using a user input device, and the annotations are displayed in the overlay window instep 340.FIG. 4 a illustrates a graphicaluser interface display 400 including adocument 410 displayed therein. As shown, thedocument 410 represents a text based (e.g., a Word document).FIG. 4 b illustrates anoverlay window 420 displayed overdocument 410 indisplay 400. As shown inFIG. 4 b, theoverlay window 420 includes annotations provided by a user; specifically the annotations shown include two handwritten “circle” marks and some text: “xxxxx”, as input by the user. Also as shown, the boundary of the overlay window is larger than the document, however, the boundary may be configurable such that the user can make the boundary smaller or larger than the document, e.g., by selecting an icon on or by the overlay and adjusting the size/dimensions thereby.FIGS. 6 and 7 show example of smaller overlays displayed over a document. Also, controls are provided to a user to change the positioning of the displayed overlay relative to the document, e.g., by selecting the overlay and dragging to a new position. - User input may include handwritten or typed text, or pasting of documents, icons or images selected from the user's system. In one embodiment, an overlay includes a transparent work area which aligns with the document, a border indicator to show the bounds of the overlay, and overlay controls. The overlay window within the border indicator is transparent, in certain aspects, to allow unfettered viewing of the document contents. The user can use standard controls to create annotations, e.g., by drawing or typing on top of an overlay, using any user input device, such as a mouse, keyboard, pen or stylus, touch-screen or touch pad, etc. The user's input will appear as if it is located (e.g., written) on top of the underlying document. In certain aspects, drawing controls include lines, standard shapes, useful icons, text and images.
- In
step 350, annotation information is stored to the system, e.g., local system memory, or persisted to a remote memory such as a database system or application server. The stored information includes the annotations provided by the user as well as positioning information such as the position(s) of annotations within the overlay window, and positioning information of the overlay window relative to the document. To facilitate the alignment of the overlay relative to the document on devices or systems having a different or alternate resolution interfaces such positioning information might include the document size/resolution, the document zoom, and the document position. Using this information an overlay can be scaled for a different interface such that it closely matches its original position relative to the document on a different interface. - In
step 360, the annotation information is shared with another user. For example, in one embodiment, the user that creates the annotations allows access to the annotations to a second user. In one embodiment, this includes sending the annotation information to the second user (e.g., the second user's computer system) by way of a network connection, such as a VPN, WAN, LAN, Internet, etc. In another embodiment, this includes enabling the second user to retrieve the annotation information, e.g., from memory or a server system, such as by sending a link to the annotation information, or otherwise alerting the second user that the annotation information may be accessed. In certain embodiments, the document may also be sent with, or retrieved with, the annotation information. For example, if the second user already has access to the document, only the annotation information need be enabled for access. This may occur where the second user is the creator of the document, or where the second user may have already accessed the document and asked the first user for comments/annotations. - In
step 370, the annotation information accessed or received by the second user is used to generate an overlay on the document on the second users system. When the overlay window is displayed with the first user's annotations on the second user's graphical user interface, the second user is able to see the annotations overlaying the document.FIG. 5 a illustrates a graphicaluser interface display 500 on the second user's system where the resolution is the same as on the first user's system, e.g.,overlay window 420 is displayed overdocument 410 in the same resolution as shown inFIG. 4 b.FIG. 5 b illustrates a situation where the second user's system has a different resolution and/or aspect ratio than the first user's system. Here the graphical user interface 550 (with a different aspect ratio for example), includes the displayed document (now 560 to indicate a different document aspect ratio or size). The positioning information associated with the overlay is used to appropriately scale theoverlay 570 so that the sizing and positions of the displayed annotations relative to the document contents closely match that in the original system. -
FIG. 6 illustrates an example of an overlay floating over a document. As shown annotations by a user are displayed in the overlay over the document (underlined “the” and an arrow pointing to Sample 2). - The first user may create a second overlay for the
document 410 and allow access to the second user. The second user may access and display the second overlay over the document in addition to the first overlay, or as a replacement for the first overlay. Similarly, a third user may create a separate overlay for the document and allow access to other users, including the second user. The second user may access and display the third user's overlay (and annotations) over the document in addition to the first user's overlay, or as a replacement for the first user's overlay. For example, in one embodiment, when multiple overlays are available for display over a document (whether created by the same user or multiple users) a visual indicator may be displayed to indicate the number of available overlays for the document and/or to allow the viewing user to select from among the available overlays. For example, the viewing user may select one, more than one, or all of the available overlays to be simultaneously displayed over the document being viewed. In certain aspects, where multiple overlays are available for display, the overlays may be color-coded according to creating user, or otherwise distinguished based on user.FIG. 7 illustrates two different overlays displayed over a document. As shown,overlay 1 is positioned over a different portion of the document thanoverlay 2. In the situation whereoverlay 1 andoverlay 2 were created by different users, they may be displayed in different colors or shadings to help the viewing user distinguish the source. Alternatively or additionally, a user indicator such as an icon or text can be displayed with the overlay to identify the source. - It should be appreciated that overlays can be shared in real-time, or in near real time, as the overlay is being created. For example, in an on-line interactive collaboration session, annotations being input by a user on one system can be transmitted to systems of other users partaking in the collaborative effort as the annotations are being created, or just after the annotations have been created (and the creating user indicates acceptance, for example).
- In one embodiment, a user is able to integrate annotations provided in an overlay into the underlying document. For example, a user may be able select or indicate 0, 1, or a number of the overlays and flatten or permanently integrate them into the underlying document. In
FIG. 3 this is represented asstep 380, where the selected overlays are considered to be ‘approved’ and therefore are incorporated into the final document. - According to one embodiment, various overlay controls are provided for use by a user. Examples of useful overlay controls include controls to create a new overlay, to save or delete an overlay, to control display parameters of an overlay. In one embodiment, one or more of the following user controls are provided:
- 1) Create new overlay. This control allows a user to create a new overlay for a document, or page of a document. Note that support for more than one overlay is useful as it allows for alternate annotations.
- 2) Save overlays. This control allows a user to save an overlay or a set of overlays, along with information relevant to the overlays and the documents (e.g., overlay size/resolution, document name, document page(s), document zoom, display order, etc.)
- 3) Delete overlays. This control allows a user to delete specific overlays or sets of overlays which are no longer needed.
- 4) Overlay notes. This control allows a user to add additional notes to an overlay which do not actually appear on the overlay (these notes are not annotations of the document). One purpose of these notes may be to provide context or background information.
- 5) Overlay display control. This control allows a user to display an individual overlay or sets of overlays. If sets of overlays are shown, the display order is respected, by default.
- 6) Overlay default color control. To help with discrimination when multiple overlays are shown, this control allows a user to set the default color for an overlay. For instance, different users could use different colors, making it possible, even when all overlays are shown, to determine who specified what.
- In one embodiment, a tool to ‘hide’ sections of the underlying document is provided. While this will not actually delete material from the underlying document (nor cause it to reflow), it will hide that section while the overlay is displayed.
- In one embodiment, to properly show an overlay across different systems or in different viewings of a document, certain pieces of information are persisted with each overlay set: the document size/resolution, the document zoom, and the document position. Using this information it is possible to scale the overlays such that they closely match their original position. In one embodiment, the position information includes a percentage of the current screen resolution. For example, if the vertical position is indicated as extending from 20% to 80% from the top to the bottom of the document (and similarly the horizontal position as extending from x % to y % from left to right) this can be used to scale the overlay over a different resolution. The pixel count can change between documents, but the percentage would remain the same.
- While the invention has been described by way of example and in terms of the specific embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
