Definitions

• the present invention is directed towards the problem of constructing, organizing, accessing and linking documents on a computer.
• documents may contain text, graphic images, geometric figures, or numerical spreadsheets, or may be compound documents made up of nested or embedded sub-documents.
• Objects within these "containers” can be arranged in any pattern with no structuring supported within the container, except further containment or nesting. Indeed, many previous systems support commands to "Clean up the window” or "Arrange icons”. Often objects may be displayed as a list of titles sorted by name, size, date, or type but the user has no way to impose his arbitrary order on the list.
• program & file intrudes in a number of ways.
• a third approach is to simply provide a window in the parent document in which the program controlling the sub-document displays its output.
• both application programs must be executing. This implies some form of multi-tasking operating system. Such an approach is taken by the current invention.
• a major difference between these existing application programs and the current invention is that their notebooks are static objects contained within a single application program.
• the number of pages, page contents, buttons, tabs, and index entries were laid out by the designer of the application, and do not change in normal operation.
• the notebook in the present invention is designed to control an indefinite number of documents created by a variety of diverse application programs such as word processors, numeric spreadsheets, drawing programs, address lists, FAX viewers, and computerized forms.
• a notebook contains an arbitrary and changeable number of these documents, one per page, which need have no knowledge that they are embedded in a notebook.
• the notebook in the present invention acts as the "job control language" for a collection of programs and their associated files. The contents of the table of contents and index change as documents are created, moved or deleted.
• the visible bookmarks or tabs can be enabled on a document-by-document basis.
• any number of pages in the present invention can be "removed” from their home position and “floated” over another page and then sent home. No known work in the prior art exhibits this set of features. Or, to state it another way, although the present invention could be used to build something much like "HyperCard", the converse is definitely not true.
• the present invention includes methods and apparatus for controlling a computer.
• the computer presents the behavior of a multi-page notebook that resides on a bookshelf containing other notebooks and accessories.
• Features include visible numbered pages, page-turn effects, tabbed bookmarks along one or more edge, "floating" pages temporarily removed from their notebook location, a table of contents, contents of sub-sections, and an index.
• a "Document Model" is presented to the user in which the existence of an underlying computer program implementing the behavior of a document is hidden.
• Each page in the notebook contains one document which may contain arbitrary amounts of data.
• These pages are analogous to the combination of data files and application programs in other computers, and may be compound documents containing different types of documents such as text, drawings, FAX images, or specialized forms.
• the user has complete control over the ordering of his documents by placing them where he wishes in the notebook.
• arbitrary linkages may be made between documents by easily-created "link buttons" placed in one document and tied to an object in another. When such a button is selected, the page of its target is turned to.
• the construction of compound documents is supported and implemented by the computer's operating system, and does not require an application program to contain any special code to support sub-documents or to be a sub-document.
• the notebook metaphor presents a virtual object which everyone is familiar with and can use: a book. Components such as the table of contents, page numbers, and page tabs are instantly recognizable and can be manipulated by a novice user. The match to a real-world object is even stronger when this metaphor is implemented on a "note pad"-style computer which uses a stylus as a pointing device directly on the screen.
• the notebook of the present invention allows the user to impose a variety of structures on his documents.
• the structure can be as simple as a list, or divided into sections, or even a large hierarchy with nested sections. This structure itself can help the user remember where documents are, and can place related documents together, and also supports a variety of retrieval paths.
• the user can flip from page to page, or turn to a specific page by selecting its tab or entry in a table of contents or index.
• the table of contents and index provide complementary browsing mechanisms, one ordered by page and one by name.
• the entries in the table of contents and index along with page tabs are all forms of link buttons.
• the bookshelf, notebooks, table of contents and documents are all independent programs embedded one within the other. This support for embedding is built of robust, well isolated operating system- level objects such as independent tasks, file directories, and display windows.
• the present invention implements an Operating System and a Graphical User Interface (GUI) on a computer's graphical display.
• GUI Graphical User Interface
• the computer presents a simplified simulation of some portion of the real world.
• Objects within the computer such as files, directories and programs are represent on the display as small pictures or icons. These icons are selected or moved around the screen by using some pointing device such as a mouse or electronic stylus.
• the goal is to provide the user with an intuitive feel for the behavior of the objects stored by the computer. This is done by allowing for their direct manipulation with the pointing device.
• Objects may be "opened”, “closed”, or “dragged” onto/into other objects.
• the most common pointing device is a mouse with one to three buttons. A cursor on the screen tracks the movement of the mouse.
• Commands are issued by moving the cursor over some area of the screen and pressing one of title mouse buttons. Pressing and releasing a button is a "click" which can be extended to double and triple clicking. Holding a button down and moving the mouse generally is used to drag the object beneath the cursor.
• An electronic stylus whose position is sensed by a digitizer can also be used as a pointing device.
• the stylus adds gestures. For example an object can be deleted by drawing an 'X' over it. If the digitizer is integrated with the display, then the cursor may be dispensed with, because the stylus can point directly to displayed objects.
• the present invention can thus be used with a mouse, stylus or other pointing devices.
• GUI software can be based on any one of many prior inventions. Information in this area can be found in Inside Macintosh, Fundamentals of Interactive Computer Graphics, SmallTalk-80, The language and Its Implementation (all from Addison- Wesley Publishing Co.), "The X Window System” (ACM Transactions on Graphics, Vol. 5, No. 2, April 1086, pp. 79-109) or “Andrew: A Distributed Personal Computing Environment” (Communications of the ACM, March 1986).

• Figure 40 shows a link button 1380 on the bookshelf tied to a word 1390 on a frequently-referenced page in the Hdp notebook 1400. When the button is pressed, the Help notebook will open and turn to the linked page.
• link buttons may either cause the target document (such as document 1370 in Figure 39) to be displayed in a second document display region, i.e. one that does not predsely coindde with the first document display region, in which the linking document is displayed.
• utilizing the link button may cause the target document to be turned to, i.e. displayed in the first document display region, repladng the contents of the first document.
• Embedding is a fundamental concept in the implementation of the present invention.
• embedding can be defined as the construction of compound documents by the nesting of autonomous documents within another document. This nesting can be carried out to any levd.
• a simple example of this is in Figure 42, showing the construction of a document containing some text 1470 and 1480 and a diagram 1490.
• This document is construded by embedding a drawing document into a text document. Without support for the embedding of independent disparate documents, the underlying text editor program would need to support the functions of a drawing program.
• a user can construct compound documents from any available document, where each document may indude an independently ordered sequence of pages.
• the embedding document may be created by one application, while the embedded document is created by a second, different application.
• the notebook takes this structure to its logical end: the entire system is built as one all-encompassing document.
• the root document is the bookshelf. All objects on the bookshelf are embedded in the bookshelf, induding the main notebook.
• the sole document directly embedded in the main notebook is the table of contents document.
• the documents embedded in the table of contents are chosen by the user. They may be of any type of documents, including multiple documents, compound documents or section documents which contain other documents.
• the embedded document is preferably displayed in its position as embedded in the embedding document in the document display region, or an icon of the embedded document may be displayed there instead.
• the text surrounding the embedded document or its icon preferably flows or wraps around it, filling in the surrounding area in the document display region.
• the notebook metaphor hides the existence of the computer programs which implement its behavior and that of the different types of documents.
• Other, earlier systems use a model in which a program is executed and can load, modify, and save data files of an acceptable format.
• all the user needs to see are documents.
• the execution of the corred program and the loading of a spedfic data file normally occurs when a document is turned-to, floated or opened from an icon.
• an embedded document may be displayed and modified by floating it in a display region above the display region in which the main
• a document may be floated over an underlying document appearing in the document display region in at least two manners: first, such that the floated document remains in its own display region when the user turns away from the underlying document (such as to yet another, i.e. third, document); and second, such that, when the user turns away from the underlying document (i.e. to a third document), the floated document ceases to be displayed.
• An identifier that uniquely identifies the type of the document is saved with the document's filed data when it is created or suspended. This identifier is used to select the appropriate program code to execute when the document is made active again.
• the present invention implements embedding as part of the main operating system software, making embedding available to all application programs that execute within this "application framework".
• An application program need contain no code to deal with accepting embedded documents or bang embedded itself.
• the application framework provides default behavior for embedded documents, but programs can override this default if desired.
• the application framework is implemented on top of a preemptive, multi-tasking operating system which supports shared code, a tree-structured file system and a windowed graphics system.
• the support for embedding is built from the common "Operating System”-level objects.
• a non-compound (or simple) document is a separate task executing the shared code for that type of document.
• the task When the user turns away from a document's page or closes its window, the task is suspended and its state is saved in a sub-diredory whose position in the directory tree corresponds to the position of the document's nesting within the bookshelf.
• This filed copy of the task's state indudes more than just the data that makes up the document. Enough information is saved such that when the task is re-started, the displayed page or window will appear exactly as it did when it last was displayed. To do this, the state of the window is also filed with the state of the document.
• the application program displays its output and accepts pointing- device input through a window whose location and size are controlled by its parent application or (by default) the application framework.
• the application framework isolates an application program within its own task, diredory and window. This isolation builds a very robust system without burdening the user with an arcane command language.
• the user can locate, execute, combine, suspend, and destroy multiple tasks by simply manipulating pages in a notebook.
• the bookshelf and its nested documents are constructed of standard components commonly found in tree-structured file systems, such as files and directories.
• the operations performed on these components are also available in all functional file systems. Because of this, it is easy to map the structure of the present invention onto a foreign file system. If this external file system can be shared by multiple machines, then a number of machines implementing the present invention can share and exchange entire notebooks through the shared medium.
• FIG 41 shows how these documents are stored in the file system of the present invention.
• Each enclosing document is represented by a directory 1420, which contains its sub-documents 1410.
• a file called “docstate.res” holds the state of the document when it is inactive.
• the text document "Org Chart” 1420 is embedded in a sedion document 1430 called “Widget Inc.” which is, in turn, embedded in the table of contents document 1440.
• the table of contents is the sole top-level embedded document within the main notebook 1450. At the highest level the main notebook is embedded in the book shelf 1460.
• the drawing 1490 is not merely a static image, but is a window or ("edit region") into a drawing document controlled by an actively executing program.
• "Tom Keating" 1510 decides to be known by his middle name (see Figure 42)
• his "box” 1500 could be re-sized and his name edited in the edit box 1520 directly in the displayed compound document (where, in this case, the embedded document is created by a different application than the embedding document), to produce the revised version shown in Figure 44.
• the embedded document here, the organization chart
• the embedded document is automatically opened in an edit region at which it can be edited, using its own application (i.e. the drawing application, as opposed to the text application of the embedding document).
• the modification of the embedded document takes place by means of alterations made with the embedded document in place within the embedding document.
• other actions may be performed on the embedding document which are also automatically executed on the embedded document, such as printing, copying, deleting, dosing (i.e. ceasing display) and saving, and so on.
• an embedded document may be printed by itself by selecting "Print” from the embedded document's "Document” menu, or the entire embedding document may be printed along with the embedded document by selecting "Print All Contents” from the embedding document's Print Setup option sheet.
• Yet another alternative is to print the embedding document only with so much of the embedded document as is displayed on screen. In each case, the print action is executed with respect to the embedded document automatically when the embedding document is printed.
• the application framework allows applications to tell the embedded objects when to file their data. This is done automatically, without the user's specific command; thus, when a user turns away from a page, the application framework tdls the application to save its instance data, which indudes any data in an embedded document.
• the larger (i.e. embedding) document is printed, copied, deleted or turned away from, the same action is automatically taken on the embedded document.
• the displayed portion of the embedded document is also printed.
• the entire embedded document may be automatically printed along with the embedding document, by selecting Print All Contents from the Print Setup options sheet.
• the application framework provides default behavior for embedded documents, parent applications can override these defaults.
• the bookshelf supports its embedded documents in two states: first, as icons 120 (see Figure 1) arranged from left to right, bottom to top; and second, as floating windows, as the "help" notebook 790 shows in Figure 19.
• a notebook causes its "children" to appear as a stacked series of numbered pages with a current page and any number of floating pages visible.
• a section document presents its children as an indented list 940, as in Figure 22.
• a text document places its embedded document 1530 in-line with the text, as in Figure 45. Opening or re-sizing the in-line document 1530 causes the surrounding text 1540 to "flow" (or “wrap around") to fill in to best fit the embedded document.
• the "Access" option card 1558 shown in Figure 47 is opened by using the "About" command from the "Document" menu 1580.
• Some embedded objects do not need the full capabilities of a document. Such “components” allow for simpler objects with less overhead.
• a link button is an example of a component. It contains three pieces of information which, taken together, uniquely identifies the target of the link. First is the unique ID of the parent document that contains the target. Second is the ID of the component or sub-document that contains the target. Third is a unique token assigned by the immediate container to the target object when the link button was created. For example, within text this unique ID is simply the offset of the target charader from the start of the text.
• the operating system uses the document ID to cause the targeted document to be visible, and passes the other two IDs to the document's underlying application program. The application program in turn ensures that the target is visible within the document's current window.
• the normal behavior for an application is to be suspended when its window is dosed or not visible. This default can be overridden by the application when necessary.
• the "out box" is a form of device output queue manager.
• the out box task executes without displaying a window, moving queued data to devices such as printers and modems.
• An application can also start its own hidden sub-tasks. For example a spreadsheet could run a task to recalculate in the background while the main task handled user interface events.
• the nested structure of documents and background execution can also be exploited by spedalized "traversal" tasks whidi need to "walk” through branches of the tree to process all the simple documents in a compound document. Examples of operations performed by sud ⁇ tasks are "seardi and replace", “bulk spell checking", and printing. These invisible tasks will start a sub-task for each sub-directory in-turn and issue spedalized requests to the executing application code.
