Description

Detailed Description of the Invention

[0001]

[Industrial application] SGML (Standard G
generalized Markup Languag
e) and ODA (Open Document Arch)
The present invention relates to a document editing device for a structured document such as an image).

[0002]

2. Description of the Related Art Originally, in editing a structured document such as an ODA document, in addition to being able to edit the document contents (text data, raster data, graphic data, etc.), both the logical structure and the layout structure can be edited. It needs to be possible. Therefore, a document editor using an independent window for editing document contents is often used.

In the current situation, in structure editing, a structure editor using an independent window different from the document content editing window for editing is often used. Moreover, in structure editing, the tree structure is displayed as the main screen,
In many cases, the contents of the nodes and leaves in the tree structure are displayed in another window.

As described above, the general approach is to proceed with the editing of the structured document by opening a number of application windows on the operation screen.

[0005]

In the multi-window format in which the text structure and the edited text are assigned to one window and displayed as in the conventional editor, a plurality of windows are displayed on the display simultaneously and without overlapping. When trying to display, the characters in each window are displayed in a reduced size, and there is a problem in that the visibility becomes extremely poor.

It is possible to use a display having a large display area as one of the simple methods for solving this, but it is not practical because the display device itself becomes large and expensive.

Further, in the generally used multi-window format, a window manager manages each window, and this window manager can move the window on the screen and manage the hierarchical relationship of the windows.

As a result, the target window can be called and edited, and the window can be freely operated. However, when the number of windows on the screen increases, the management becomes complicated, and there is a problem that the user has many operations unrelated to the original editing work.

Further, in a general display, the maximum number of windows that can be displayed on the screen at the same time without overlapping is two windows. There is also a problem that it is difficult to edit while checking the windows at the same time.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention edits and manages the structure and attributes of a structured document and a content management unit that manages text editing and editing of images, tables and figures. The logical structure management section that performs the above and one application window are divided into several display areas, and the logical structure editing section and the document content editing section are assigned to each area to simplify the window operation, the same as a word processor. The editor is characterized by being able to input a document by such operations.

[0011]

The present invention is characterized in that the editing of the document contents can be handled with a feeling of use similar to that of a word processor, and the editing work of the logical structure can be performed while referring to the document contents. This editor is basically designed so that almost all work can be done in one window, and the window area is divided into several functional areas for use.

Here, one window is divided into five display sections as shown in FIG. 2A, and each area is divided into a logical structure editing display section, a document content editing display section, various command button display sections, Various conformer button displays,
It is then assigned to the document allocation display section.

In the present invention, among the above five display units, the logical structure editing display unit and the document content editing display unit are shown in FIG.
As shown in (b) and (c), the screen areas are overlapped and used together.

In the columns A and B, the tree structure corresponding to the logical structure is displayed for several layers with the logical root at the head, and in the columns C and D, the basic logical objects are displayed to display the document contents. The contents of are displayed as plain text according to the sequential order. There, the display of the document contents is changed in correspondence with the display contents of the logical structure.

In column I, commands relating to editing work such as a shift command to the layout display used during editing, a shift command to the editing work used during layout display, and a page turning command are arranged in icons.

The column M is used for displaying a confirmation button for executing a command relating to an edit menu such as deletion, movement, generation of an object issued during editing work, and an error display after execution.

[0017]

FIG. 1 shows the functional configuration of an embodiment of the present invention. Moreover, the screen configuration of the window is shown in FIGS. 2 (a), 2 (b) and 2 (c).

The structured document editing apparatus of the present invention has a management unit that manages each editing unit, and further has a document data management unit 1 that controls the management unit. Document data management unit 1
Controls requests from the input unit 6 such as a keyboard and a mouse and each management unit. For example, when the event from the input device is determined and assigned to which editing section, or when the change due to editing reaches another management section, the change is made through the document data management section 1. If the display is changed, a request is simultaneously issued to the display control unit 4.

Next, a detailed description of each management unit will be given.

The logical structure management unit 3 includes a logical structure editing unit 31.
And display control of the tree structure corresponding to the logical structure,
This is the part to be edited.

As shown in FIG. 2B, the column A of the display section is displayed.
A column B is a logical structure display area, and the tree structure of the structured document is edited through this area. In the initial state, the logical route is displayed in the column A, and the logical object corresponding to the child object is displayed in the column B. When any object displayed in the column B is selected, the display of the object moves to the column A, and the child object of the object newly displayed in the column A is displayed in the column B. Change to a state.

As described above, the column A represents the hierarchical relationship (depth) of browsing from the logical root, and the column B always refers to the currently displayed display object (hereinafter referred to as "current object") of the column A. You are displaying a child object.

As the editing function, object generation,
Delete, move, copy and check, change and set attribute values. And all these functions are basically column B
(Exception, column C can be deleted). The processing procedure of these functions is shown in FIGS. X in Figure 3
4 and X in FIG. 4, and Y in FIG. 3 and Y in FIG. 4 are connected to each other.

To generate an object, if a command for generating a command menu is issued after selecting an arbitrary object in column B, a further hierarchical menu is displayed. In this case, the class of the current object has Only the instantiation of a class that satisfies the condition of generator for subordinate (hereinafter referred to as GFS) is allowed.

Then, for the generated object, if it is a complex logical object, a basic logical object which must be hung down due to the nature of the class is also generated at one time.

For example, the GFS of class paragraph P
Is {option class TITLE, seq
uence class TEXT}, when an instance of this class paragraph P is generated, an instance of one class text hanging in the generated paragraph at the same time is generated, and on the document content editing section (column An object whose content part is empty is displayed in D). Of course, one icon indicating the text object is also generated in the column C.

In deleting an object, when an object to be deleted is selected and a delete command is issued, it is deleted after checking whether or not the object can be deleted in the logical structure, and at the same time, some icons in column C and the column The contents of D disappear from the screen.

In this case, the erased column C and column D objects are the column B that issued the delete command.
This corresponds to the basic logical object group which is also in the search state in the column C when that object is placed in the search state and the portion of the column D showing the content part thereof. If it cannot be deleted, the command execution is stopped.

In the above example, when the paragraph P is the current object and only one text object is displayed in the column B, this text object cannot be deleted, so the execution of the delete command is aborted. Will be.

In moving an object, when an object to be moved is selected and a move command is issued, it is checked whether the selected object can be deleted and can be moved to the destination, and then the object is moved. If either check fails, the move command is canceled.

In copying an object, when an object to be copied is selected and a copy command is issued, it is checked whether the selected object can be copied to the copy destination, and if it is possible, the copy is performed. If not possible, the copy command is canceled.

In this embodiment, the case where two columns are used has been described, but the complexity of the logical structure of the ODA document to be processed (meaning that the hierarchy of the tree structure becomes deep).
Accordingly, by increasing the number of columns having a function corresponding to the column B, it is possible to represent a larger number of tree structures than in the present example, which makes it easier to perform structure editing.

The content management unit 2 includes a text editing unit 21 and
It consists of a group of editing tools for editing figures and tables. The text editing unit 21 is a part for displaying and editing an object having a text attribute in the contents of the ODA document to be edited. Columns C and D are windows that provide the function of the text editing unit 21, and are functional blocks that realize the function of the text editing unit 21.

In text editing, the content parts of all the basic logical objects that are instances of class text are viewed as plain text of about 40 characters per line, and they are sequentially arranged according to the document sequential order. The entire document contents are displayed by arranging them.

That is, regardless of whether the text objects have the character contents assigned to the left side of the double-column display or the assigned results have the text contents of 20 characters per line, they are all the same. It is decided to treat it as plain text. This is because, considering that many of the basic logical objects are instances of class text, first of all, text editing is easy to do.

Further, the basic logical object is a figure (graphic,
In the case of an image) and a table, as shown in FIG. 5, an icon indicating the attribute is displayed in the column C, and an icon indicating that is displayed in the column D. Here, in order to display and edit the contents of those objects, various editors are called by selecting an icon. Separately, a new window is created, but these are also controlled so as not to go out of the application window area.

Column C has a pair of relationships with column D,
It is always displayed in sync on the edit screen. In column C, for each basic logical object, an icon is displayed to distinguish the attribute of the object, whether it is an instance of class text, a class figure, or a class table.

In column C, logical editing such as object deletion can be performed. This is because the editing operation of the logical structure editing unit 31 can only be performed by the text editing unit, and the deleting operation is the logical structure editing unit 31.
There is no difference. In column D, the text data contents can be directly edited (addition / deletion / copying, etc.).

"Current", "Noncurrent", and "Search" are used to express the logical structure of all the basic logical objects included in a document.
There are three "modes".

When considering a tree structure having the current object as a root, it is assumed that the basic logical objects corresponding to the leaves of the tree structure are a group of objects in the current state. Further, it is assumed that the other object groups are in a non-current state. For example, in FIG. 6, when considering a tree structure in which the object 330 is the root, a range 331 indicates an object group in the current state. The remaining objects are all in non-current state.

Then, the states of the icons displayed in the column C are changed to distinguish the objects in the different states. Further, when considering a tree structure in which any one of the objects displayed in the above-mentioned column B is set as a root, it is assumed that the basic logical object corresponding to the leaf of the tree structure is an object in the search state, and the current and The state of the column C, for example, the color and reverse display are changed so that the object can be distinguished from the non-current state object.

In particular, in the search state, not only the state of column C is changed by selecting the object of column B, but even if the object of column C is selected, the display state of the object of column B as well as column C is changed. As a result, it becomes possible to follow the logical structure from the content side.

That is, the search state is a state in which a more specific object is selected from the object group in the current state. It is applied to the objects in columns B and C, and the display is changed so that it can be distinguished from other objects in the current state in terms of display.

FIG. 7, FIG. 8 and FIG. 9 show flowcharts of the operation in each column.

As described above, by providing the three modes, the association between the document content and the logical structure can be visually intuitively provided, and a unique operation environment can be provided in the logical editing. Also, as described above, when the basic logical object is a figure (graphic, image) or table, various editors are called by selecting the icon of column D indicating that. is there.

Furthermore, a major feature of the content management unit 2 is that it can be linked with the layout display processing unit 5 (viewer). Documents are allotted and displayed by the viewer, but if you select the part for which you want to edit the content in that state, the display returns to the content edit display in Fig. 2 (b), and column D
Since the portion of the document previously selected in is displayed in the central portion of the column, it is possible to move to editing work without performing extra operations.

Further, as another contrivance regarding interlocking with the viewer, in the above-mentioned logical structure editing unit 31,
The current object has been described, but the page to which this current object is allocated is set to be the initial screen for viewer output.

That is, in the layout display of a document extending over several pages, every time the layout display image of the document is changed by editing the content or logical structure, it is displayed from the first page. If you want to check the page layout result of the page that contains the sentence and the page after the first page, it is thought that some page turning operation will be performed, and by omitting that operation, a simpler operating environment is provided. The purpose is to do.

From a WYSIWYG environment system, this may only switch the display screen and the edit screen, and may not be special. On the contrary, it is an editing work in a situation where the actual layout display image is unknown, and there may be some opinions that it is a drawback.

However, at present, there is no system that realizes WYSIWYG as a native system in the ODA editor. Considering that, I think that it has a great advantage as it is closer to the WYSIWYG operating environment.

In other words, as described above, the present invention is characterized in that document content editing can be handled with a feeling of use similar to that of a word processor. Further, by integrating an editor and a viewer, it is basically possible. It can be said that the work is carried out with one window open, and it is free from the troublesome window operation when considering the usage environment on a personal computer or the like.

Here, the reason (necessity) for dividing the function between the column C and the column D will be described.

As mentioned above, if the "mode" expression in column C is to be expressed only in column D, it is possible. This means that the number of columns will be reduced by one and the screen will be simpler and better.

As an example, it is possible to change the color of the sentence or icon character that displays the content part of the target object, or to change the background color of the character, or to display a border surrounding the entire content part. There are several possibilities, such as using something like this to change the color, but I found that the method of the invention was the best because it made it difficult for everyone to see the contents.

A column I is an area for displaying icons of commands for performing overall operations of the editor such as saving a document, calling a document, and ending the editor.

Finally, the column M will be briefly described.

With respect to the function of each editing unit as described above, this is a warning display at the time of misoperation when executing various commands, a display for confirming command execution, and a notification of command execution cancellation. It is used for warning display. In addition, when an object is created, if multiple objects that become parents of the created object match from the GFS relationship between the object that you want to be the parent and its sibling object, use it to display buttons for parent selection operations. ing.

Next, the operation of each management section described above will be described based on an example of editing operation.

FIG. 10 shows an initial screen in which the editor is started. Here, the document input in advance is called. The logical structure of this document is displayed in columns A and B. In columns D and C, icons indicating the content of the document and the attributes of the object are displayed. Therefore, suppose that the following example sentence is added.

(Example sentence) "Claim 3 Structured document editing apparatus according to claim 2, characterized in that the display area is divided into a plurality of portions so that the structured document can be edited in one application window." Here, if the user knows what kind of parent-child relationship the object [Claim] of the above example sentence has in the logical structure of the document being edited, it should be added through the logical structure editing unit (column B). Find the position.

The document to be edited has a logical structure as shown in FIG. Therefore, first, the object 301 displayed in column B on the screen of FIG. 10 is selected as the ancestor of the target object. The object 301 moves to the column A, and the child object of the object 301 is displayed in the column B.

At the same time, in column D, the object 301
Is displayed. The screen of FIG. Further, when the object 302 is selected, the object 302 is moved to the column A in the same manner, and the child object of the object 302 is displayed in the column B. The target object is displayed (FIG. 12). Here, the icon 303 indicates a non-current state.

Next, in order to insert the example sentence, an object called a claim is created. The screen of FIG.
Display a command menu 304 like 3 (a),
When the command 309 “generate” is selected, the object menu 305 is displayed as shown in FIG.

Further, the item 310 "Claims" is selected from the object menu 305. The menu 305 shows a list of objects that can be created and are described in GFS. That is, it is a list of objects that can be created as children of the object 302. As a result, a new object is created and the screen shown in FIG. 14 is displayed. The object 306 is a newly created object, and the icon 307 is an icon indicating the content part of the newly created object.

On the contrary, when the logical structure is not known, the screen is scrolled by the column D as in a general editor to find the insertion position. Here, if the icon 311 in the column C is selected, the screen becomes as shown in FIG. 12, and it is possible to know what kind of logical structure the object claim is. Create a new object as described above.

After that, when the above example sentence is input from the keyboard, the screen shown in FIG. 15 is displayed.

Here, when the command icon 316 in the column I is selected to see how the inserted sentence is printed, the screen shown in FIG. 16 is displayed. Thus, the part of interest is displayed on the allocation display screen. On the other hand, the place where you want to edit on the allocation display screen 31
If 5 is selected, the content edit screen of the target portion, FIG. 17, is displayed, and editing can be performed without performing extra operations.

The sentence inserted previously is deleted. After selecting the object to be deleted, the command menu 304 is displayed as in the insertion, and the command 308 Delete is selected. As shown in FIG. 18, a confirmation message and a button for confirming execution are displayed in the column M. Here, if button 313 "YES" is selected, it is deleted, and button 3
If 14 "NO" is selected, the deletion is canceled.

It can be seen that the editing is performed with such a feeling, and unnecessary operations on the window are eliminated as much as possible.

[0070]

The advantages of the present invention are the following four points.

(1) Regarding the display of the logical structure, the logical structure editing section 31 and the document content editing section 21 are provided with the concept of a current object and three modes (current, non-current, and search), and the logical structure of the document (tree Not only the logical structure of the document but also the part of the logical structure where the document content part itself is placed can be immediately displayed by displaying both the (structure) and the document content while expressing the change of the mode state. You will be able to know.

In addition to the representation of such a mode state, the contents of the basic logical object included in the current object are placed at the beginning of the document contents display unit of the document contents editing unit 21 so that the contents of the document contents editing unit 21 is reached. Depending on the display position of the display content, such as changing the display in
The device is designed to clarify the relationship between the logical structure and the content part.

(2) When editing the document contents, the contents of all the basic logical objects are displayed as plain text of about 40 characters per line, which means that the work is being carried out toward a word processor that is generally popular. You can work with almost the same feeling.

In addition, from the relationship with (1), in editing the logical structure, it is possible to confirm what kind of logical meaning the document contents have in the document on the screen displaying only the logical object. When logical editing (creating, deleting, moving, copying, etc. of an object) is performed, the work proceeds while immediately confirming how the result is reflected in the document contents.

(3) A viewer for allocating and displaying the ODA document is provided, and the output image of the edited document can be confirmed in the same display area. Moreover, on the image display screen, if you select the part to be edited next, after switching to the content edit screen,
The part to be edited (display of text data, etc.) is displayed in the center of the content editing screen, and it is possible to immediately proceed to editing work.

Therefore, in the case of content editing such as after confirming the layout display, extra window operation (not to mention switching of application windows, no matter what position the content section is displayed in the document content editing section). , Which means performing appropriate screen scrolling on the system side) is unnecessary, so-called WYSIWY
Realizes operability similar to G environment.

(4) The functions (1) to (3) described above are
It's all done in one application window. The current GUI (Graph)
In the user interface environment, it is possible to execute and confirm a plurality of applications by opening a number of windows.

However, although it is possible under a machine environment having a large display, a plurality of windows can be opened on a screen of a relatively small display area such as a personal computer which is widely used in general households, but those windows cannot be opened. The current situation is that the necessary screens are not displayed unless the window positions (up, down, left and right) are manipulated.

That is, various editor windows (logical structure editing, content editing, table editing, raster figure editing, geometric figure editing, etc.) and allocation result confirmation (viewer)
There is a window for and you can't proceed unless you show or hide them.

In this respect, according to the present invention, the editor and the viewer are integrated, and there is an effect that the work is advanced with only one application window opened, and the troublesome window operation is released. In particular, it has a very excellent effect when it is composed of a small-scale device such as a personal computer.
