- An advantage of this arrangement of information on the display 48 is that it provides an integrated document development system which allows simultaneously displaying a document being developed, detailed changes made thereto, as well as a brief history of the changes made during the development process. Further, an unedited version of the document being developed may be accessed at any stage during the development.
- the document file 92 includes data defining the document being developed, and the content of the message file 94 typically includes data corresponding to at least a portion of the viewable information associated with the document file 92. For example, a subportion of the viewable information of document file 92 is enclosed by a rectangle employing the tool palette 91 , defining an annotation 98 which is discussed more fully below.
- the content of the message file 94 is related to the annotation 98.
- the message file 94 recites "I do have a question about the door at the circular bridge connects . . . . "
- the document file 92 shows a visual depiction of information associated with the content of the message file 94.
- each message header 96 provides a summary of the content of a message file 94.
- a plurality of message headers 96 are provided, each corresponding to a different message file 94 and having an icon 96a and a line of text 96b disposed adjacent thereto. With the plurality of message headers 96 being displayed in region 82, a brief history of the message files 94 associated with the document file 92 is provided.
- the message header 96 corresponding to the message file 94 being displayed has a background 96c which optically contrasts with the background associated with the remaining message headers 96, i.e., the message header 96 is "highlighted".
- the highlighted message header 96 recites “Scheme Approval” .
- the message file 94 associated therewith recites "I do have a question about the door at the circular bridge connects . . . . " With this arrangement, the message file 94 and the message header 96 both provide a description of a subportion of the viewable information, typically the subportion corresponding to the annotation 98.
- the tool palette 91 has one or more tool-defining regions, shown as 92a-92j and is employed to create the annotation 98.
- Each of the tool-defining region 92a-92i specifies a predetermined operation that modifies a subportion of the viewable information of the document file 92, defining an annotation 98.
- An example of an annotation 98 is shown as an oval, however, the annotation 98 can be of any shape desired and may include alphanumeric characters, depending upon the tool-defining regions of the tool palette 91 , as well as the file format of the document file 92.
- the document file 92 will be discussed as being a vector- based file commonly associated with computer aided design programs and systems.
- part of the viewable information is defined by view parameters, such as magnification, rotation, layer, window coordinates.
- view parameters such as magnification, rotation, layer, window coordinates.
- the tool palette 91 provides tool-defining regions which support, inter alia, operations associated with aforementioned view parameters. Examples of such tool defining regions are a pointer tool 92a employed to select areas of the document file 92 to be modified, such as by deletion.
- a hand tool 92b may be employed to pan the viewable information associated with the document file 92 along any direction in the plane of the region 86.
- a zoom tool 92c may be employed to increase or decrease the resolution of the viewable information.
- a box tool 92d- facilitates surrounding an area of the viewable information with a rectangle or other polyhedron, and a filled box tool 92e makes the viewable information within the area opaque.
- Other shapes may be provided to achieve the same results by providing an oval tool 92f and a filled oval tool 92g.
- Other shape tools may be user defined with an irregular object tool 92h.
- An arrow tool 92i allows pointing to a particular section of the viewable information, and an arc tool 92j is employed to create arcuate lines.
- the virtual buttons 88a and 88b are provided. Specifically, to post a new message file, virtual button 88a is activated by execution of a cursor event proximate thereto. This produces a message file, in a window 95, having no content associated therewith, and the document file 92 corresponding thereto is in an original state. In this example, an original state is defined as being at minimum magnification, with no annotation 98 present therein. Thus, viewable information corresponding to a project is displayed in region 86. To produce the information associated with Fig. 8, a user would activate tool-region 92c and magnify the document file 92 to the desired resolution providing the detail necessary to clearly provide a visual depiction of the message file 94, generating modified view parameters that are associated with the viewable information.
- Locating a desired position in the document file 92 may be achieved by employing the hand tool, associated with tool-defining region 92b. To precisely delineate the area of the viewable information of the document file 92 being described, tool-region 92e is activated and the cursor 60 is placed on the region shown therein, producing annotation 98. After the portion of the viewable information of document file 92 has been located, the content of the message file 94 corresponding thereto is entered by placing the cursor 60 over the window 95 and initiating a cursor event. Text is entered using a standard QWERTY keyboard.
- a graphics file or an audio file may be entered into the message file 94, such as graphics file 89, shown in Fig. 10.
- the message is sent to the ReviewIt TM server 10a via initiating a cursor event occur proximate to virtual button 97.
- the message is saved on the ReviewIt TM server 10a with the view parameters.
- the icon 96a of the same is located to the left side of the region 82. This produces a message header 96 in region 82 which corresponds to the newly created message file 94 in region 82.
- the modified viewable information associated with the document file 92 is displayed as it appeared in region 86 when the message file 94 was sent, i.e, the same magnification and identical annotation 98 in the area of the document file 92 displayed. This is referred to as context preservation and is discussed more fully below. However, all of the viewable information associated with the document file 92 is accessible. This allows a user to manipulate the viewable information associated therewith so as to display a completely different area of the document file 92 at a completely different magnification. Upon exiting and retrieving the same message file 94, the modified view parameters are restored along with the modified viewable information.
- Accessing a particular message file 94 may be achieved employing either the message headers 96 or annotations 98 on a document file 92. For example, highlighting a particular message header 96 and initiating a cursor event displays a message file 94 with content summarized by the highlighted message header 96. Were a document file 92 displayed to have multiple annotations 98 present thereon, the cursor 60 may be positioned to highlight the desired annotation 98. Thereafter a cursor event would display the message file 94 associated with the annotation 98, referred to as graphical indexing. Moreover, a boolean search technique may be employed by highlighting virtual button 88c and initiating a cursor event.
- a dialog window (not shown) would appear in the window 80 and provide an area to enter search terms, as is well known in the prior art.
- virtual button 88b is activated by initiating a cursor event proximate thereto.
- analogous steps are taken to post a reply as is necessitated to post a new message, except that the message header 96 corresponding to the reply message is positioned below the selected message to which a reply is being posted, offset from the left side of the region 82.
- the plurality of message headers 96 provide a historical summary of the message files corresponding thereto, but they also describe the sequence of communications between users posting the same.
- the spatial position of each message header 96 is dependent upon a position of the communication, corresponding thereto, amongst the sequence communications. In this manner, the ReviewIt TM server 10a provides an entire history of the development of a document in a centralized location.
- a creator of a project may be sent an e-mail each time a project is accessed by a user.
- Various information may be supplied to the creator, including the project and files accessed, the duration of the access, any message files 94 posted and the modifications, if any, recited therein.
- the cost implication of modifications to a project may be modeled.
- authenticity and authorization of modifications to a project may be controlled by implementation of electronic signature techniques. This could be implemented to reduce cost overruns, particularly useful in public sector civil engineering contracts. Referring again to Fig.
- an important aspect of the present invention is to provide high-speed data communication between the client terminals 12 and the ReviewltTM server 10a while providing the full flexibility of the integrated system.
- the ReviewIt TM server 10a bifurcates the data transmitted to a client terminal 12, concerning a document under development, into single and multiple server call data.
- the single server call data is transmitted to the client terminals 12 as soon as a project is opened.
- the multiple server call data is transmitted after an additional server call has been transmitted by the client terminals 12 after a project has been opened.
- Examples of single server call data are the message headers 96 and the annotations 98.
- Examples of multiple server call data is the message content and the view parameters.
- a client terminal 12 Upon initializing a server call, a client terminal 12 immediately receives the message header 96 and the annotations 98 associated with a document file 92. This provides the information necessary for a user to quickly view the history of message files 94 concerning a document file and determine which message is desired.
- a user Upon finding the requisite message header 96, a user initiates a cursor event, thereby taking advantage of message context preservation, as discussed above. Specifically, the contents of the message file 94 are displayed, as well as, the document file 92, with the document file 92 being displayed in accordance with the view parameters previously modified. Alternatively, a message file 94 could be displayed employing the graphical indexing technique discussed above. In this fashion, a user would place the cursor 60 on an annotation 98 desired and initiate a cursor event. This generates a server call over the network, retrieving the content information of the message file 94 associated therewith, along with the view parameters, if any.
- the code employed to implement the present invention is object based, such as C+ + .
- the objects are divided into a plurality of classes.
- the classes include a message explorer class 202, a document viewer class 204, a node view class 206, a coordinator core class 208, a document class 210, and a message node class 212.
- Each of the objects in a class includes data and methods.
- the data and methods concerning the content of the message files 94 and the view parameters of the document file 92 associated therewith are encapsulated in objects of the message node class 212.
- Data and methods concerning the document file 92 are encapsulated in objects of the document class 210.
- Coordinator core class 208 entitled CoordinatorCore::post_message() which retrieves annotation data, document file data and the view parameters, at step 302.
- the aforementioned information is retrieved from the Document Viewer class of objects employing the member method of that class entitled the DocumentViewerCore: :get_annotation().
- DocumentViewerCore::get_annotation() method retrieves data members of the Document class 210. Specifically, the DocumentViewerCore::get_annotation() method retrieves the serialized annotations employing the serialize_annotation_data() method, as well as the view parameters employing the CubusDocument::get_document_specific_data() method. The aforementioned data members are then associated with the MessageNode class 212, at step 304, allowing the same to be immediately available for subsequent requests. Thereafter, at step 306, the CoordinatorCore: :post_message() method continues processing the data members associated with the Message Node class 212 which are then transmitted to the server 10 for long term storage and subsequent retrieval.
- a user selects a message, at step 400, in the threaded message view by highlighting the same as discussed above.
- Control passes from the client terminal 12 to the ReviewIt TM server 10a by implementing the SftTreeNodeView: :on_selchange() method associated with the objects of the Node View class 206.
- the data members associated with the message file 94 are retrieved, at step 402.
- the data members of an object generated by the message being retrieved in the Message Node class 212 contains all the information to that particular message. This information includes, inter alia, view parameters and message content data.
- the resulting Message Node's select() method is then called.
- the Coordinator Class' select_message() is called, passing the previously retrieved Message Node class 212 data members to determine if the desired message is already cached in the client terminal 12, at step 404. This is achieved by testing the values of the cache, in this case, specified addresses in RAM 98, to determine whether a null is present. If the values are not null, then the data is retrieved therefrom at step 406. If a null is present, a request is sent to the server to retrieve the desired information via the request_message() method of the Coordinator class 208, at step 408. The data is then transmitted to the client terminal 12 employing the process mrspO method of the Coordinator class 208, at step 410. The message is implemented in the select_message() method of the
- This method retrieves the view parameters employing the get_field() method associated with the Message Node class, which is then passed to the current document file 92 via the document's set_document_specific_info() method associated with the Document class 210, at step 412.
- the Message Node class 212 data members are then passed to the
- the Message Explorer class in the update_preview() method.
- the Message Explorer object get the message content from the data members associated with the Message Node class employing the node's get_field() method. Thereafter, the resulting buffer is passed to the set_formatted_text() method to display it, at step 414.
- the end result is that the document viewer changes its display to restore the view to the original author was looking at when the message was created.
- the document file 92 could be a text based file, such as a common wordprocessor file.
- view parameters associated therewith could include character attributes, e.g. , italics, bold, underline and the like, as well as text and graphic boxes.
- the above embodiment illustrates use of the present invention in a CAD environment. It should be understood that the embodiments of the present invention can also be applied to other situations in which collaboration is required.
