Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus which manages a plurality of documents including a plurality of document elements.

[0002]

2. Description of the Related Art Conventionally, cut-and-paste has been performed as a method of defining the contents of a document as the contents of another document. For example, consider the case where there are several papers and an abstract is created. FIG. 2 shows the article-type document data, and FIG. 3 shows the abstract-type document data.
These follow the SGML description method, and the document element starts with the document element start symbol “<xxx>” and ends with the document element end symbol “</ xxx>”. Here, the character string “xxx” includes the document element name of the document element. The character string between the document element start symbol and the document element end symbol is the document element content. Hereinafter, in the present invention, the document element is assumed to be composed of the document element name and the document element content. However, it does not matter if other secondary information is included. Here, if the content of the document element <abstract> of the thesis-type document of FIG. 2 is to be directly brought to the content of the document element <itemparamgraph> of the abstract-type document of FIG. 3, first, the document element <ite
The content of “maragraph>” was deleted, and the content of the document element <abstruct> was cut and pasted and pasted at that location.

Alternatively, there is an example such as hypertext. This is realized by linking the contents of other document data. For example, a button 47 is embedded at the place where the link is made, as shown in FIG. The button 4
When 7 is clicked, another window appears and the contents of other linked document data are displayed.

[0004]

However, in the cut-and-paste method, when the common part is corrected in one of the paper and the abstract, the other must be corrected again. This is not efficient and has the drawback that if you forget to correct it, the paper and abstract will be inconsistent.

Although a method of attaching a link solves the above problems, in order to display document data on the screen,
Since the button is clicked and displayed in another window, there is a drawback that the number of windows becomes large and the screen becomes complicated when shared in multiple.

In addition, since the document data including the layout is shared, the layout cannot be changed and displayed for each document, and a layout suitable for the context of the document cannot be obtained. .

[0007]

In order to solve the above-mentioned problems, according to the present invention, a document processing apparatus for managing a plurality of documents including a plurality of document elements is provided with a plurality of document elements of a first document. Designating means for designating a document element having content to be shared with the second document, separating means for separating the content of the document element designated by the designating means from the first document, and separating by the separating means. First defining means for defining the content of the specified document element so as to be referred to from the first document as the content of the designated document element, and the content of the document element separated by the separating means is the first Second definition means for defining the content of a predetermined document element of the second document so that the second document refers to the content.

According to another aspect of the present invention, a document processing apparatus that manages a plurality of documents, each document including a plurality of document elements, by setting management information in each document, stores the first document Designating means for designating a document element having a content to be shared with the second document from a plurality of document elements; setting means for setting new management information for the document element designated by the designating means; In the first document, control means for controlling the document element designated by the designating means to be managed by the management information set by the setting means instead of the management information for the first document element, As the content of the designated document element, the first definition means that defines the management content of the management information set by the setting means, and the content of a predetermined document element in the second document And a second definition means for defining as referring to the management contents of the management information set by the setting unit.

According to another aspect of the present invention, in a document processing apparatus that manages a plurality of documents including a plurality of document elements, the plurality of document elements of the first document should be shared with the second document. A document element having content is designated, the content of the designated document element is separated from the first document, and the content of the separated document element is used as the content of the designated document element. A method of processing a document, wherein the content of the separated document element is defined to be referred to from a document, and the content of the separated document element is defined to be referred to from the second document as the content of a predetermined document element of the second document. And

According to another aspect of the present invention, in a document processing apparatus that manages a plurality of documents, each document including a plurality of document elements, by setting management information in each document, A document element having a content to be shared with the second document is designated from a plurality of document elements, new management information is set for the designated document element, and the designated document element is set to the first document element. Instead of the management information for one document element, control is performed so that the management is performed by the set management information, and the set management information is managed as the content of the designated document element in the first document. The document processing method is characterized in that the content is defined so as to be referred to, and that the management content of the set management information is defined as the content of a predetermined document element in the second document.

【Example】

(Embodiment 1) Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the basic arrangement of a document processing apparatus according to an embodiment of the present invention. In the figure, 1 is a keyboard for inputting characters and commands, 2 is a mouse for designating a display range and selecting a menu,
Reference numeral 3 is a CPU for executing various controls and processes according to programs, and 4 is a CRT for displaying data.
Reference numeral 10 is a storage device for storing a program to be executed by the CPU 3 and various data, and 20 is an auxiliary storage device for permanently holding the program and data, which are connected to each other via a bus 9. . The storage device 10 and the auxiliary storage device 20 may be used as a program / data holding storage device without distinguishing between them.

The storage device 10 stores a shared content independence program for making the contents to be shared by a plurality of document elements independent. The auxiliary storage device 20 stores article data 21 and abstract data 22. Here, the paper data 21 has a file name "art",
It is assumed that the abstract data 22 is stored under the file name "abst".

The operation procedure of this embodiment will be described below with reference to the flowchart of FIG. First, step S501
Then, the documents on the src side and the dst side are displayed on the window 41. A document is selected by inputting a file name or the like. Here, the file name "a
It is assumed that documents "rt" and "abst" are selected.

FIG. 7 shows a display example of the CRT 4 when sharing is performed. In the figure, 42 is a sharing button displayed for instructing sharing, and 43 is a mouse cursor. Documents on the src side and the dst side are displayed in one window 41. For example, in the upper part of the window 41, the document of FIG. 2 which is the src side document and in the lower part of the window 41 which is the dst side document.
Is displayed. Next, in step S502, the document element on the src side selected by the user is detected, and in step S
In step 503, the document element on the dst side selected by the user is detected. This selects the document element on the dst side and the document element on the src side by dragging with the mouse 2. FIG. 8 shows a display example when the document element contents on the src side are selected by dragging. The shaded area in the figure is selected and displayed in a shaded manner. The processing up to this point can be realized by a conventional technique such as an SGML document editor on a multi-window system.

Next, when the share button 42 is clicked, the shared content independent process is started in step S504. This shared content independent processing will be described with reference to the flowchart of FIG. First, in step S601, sr
See if the content of the document element selected on the c side is already shared, ie is a reference to other data. If the document elements are not shared, the data itself is the article data 21, so
Since it is “no”, the process proceeds to step S602. Also, if this content has already been shared, the description will refer to the data to be shared by the processing described below, so
In that case, the process proceeds to step S604.

In step S602, the content of the document element selected on the src side is cut out, the shared data 23 is newly allocated to the auxiliary storage device 20 as a storage location, and the shared data 23 is stored therein. In this example, “Irohanihohet, Chirinuruwo” is stored as the shared data 23. Also, the file name of the shared data 23 is generated. For example, sr
A number is added to the end of the document file name "art" on the c side to make "art01".

In step S603, the description of the shared partial data 23 is changed to the content of the document element selected on the src side. For example, in SGML, there is a description method called entity reference. In the document type declaration part, the entity "art01" is the file "art01"
The content of the file referred to here can be handled as document data by describing that the content of the above is used and describing "&art01;" instead of the content of the document element. Specifically, the file "a
The part of "Irohanihohet, chirinuruwo." of the article data stored in "rt" is rewritten as "&art01;".

In step S604, the contents of the selected document element are changed on the dst side similarly to the src side.
The description refers to the shared part data 23. Specifically, the part of "Wakayotareso." Of the article data stored in the file "abst" is rewritten as "&art01;".

As described above, the content of the document element on the dst side and the content of the document element on the src side are shared by referring to the same content stored separately. After that, when the documents on the src side and the dst side are re-displayed on the window 41, both refer to the contents of the shared data 23. Therefore, as shown in FIG. Is performed. Then, on the src side, when “Irohanihoheto, Chirinuruwo.” Shared with the dst side is rewritten as “Irohanihoheto, scatter,” the content of the shared data 23 is actually changed to “Irohanihohet, scatter,”. . Therefore, when the document is re-displayed on the dst side, the changed contents of the shared data 23 are referred to, so that the first item of the bulleted item is changed to “[ABC] Irohanihohet, scatter through”.

(Embodiment 2) In the first embodiment, the shared portion is simultaneously selected on the src side and the dst side, and the shared content independence process is executed at the timing when the sharing instruction is given.

In this embodiment, in the document on the src side,
The first half of the shared content independence process is operated at the timing at which the sharing target is selected and it is instructed to provide the shared data. This timing may be set, for example, when an "offer" button for instructing provision is prepared and this button is pressed.

In this case, steps S601 to S603 of the flowchart of FIG. 6 are executed. Then, a reference destination (for example, a file name of shared data) is stored in a share buffer (not shown) in the storage device 20. Then, in the document on the dst side, a place where the content is desired to be the same as the shared data is selected, and the latter half of the shared content independence process is operated at the timing when sharing with the designated data is instructed. In this case, step S604 of the flowchart of FIG. 6 is executed. However, the reference destination is the one stored in the share buffer (not shown) in the storage device 20.

According to this embodiment, when sharing the contents of many document elements with the contents of one document element, if the sharing permission declaration is made, the pointer of the contents of the document element is stored in the share buffer. After that, it is only necessary to detect the document element on the dst side. Therefore, each time, sr
It is efficient because it is not necessary to display both documents on the c side and the dst side and select both document elements with the mouse.

In addition, when the sharing permission is declared, the shared document provider can specify the sharable portion, so that there is an advantage that it is not shared unnecessarily by another person.

(Third Embodiment) In the above-described embodiment, the document data is described in the text format and stored in the file.
On the other hand, in the present embodiment, a case will be described in which persistent data is stored as a memory image in an object database or the like.

FIG. 10 shows the article data 21 and the abstract data 22 managed in the object database. The processing of this embodiment will be described by taking these data as examples.

The article data 21 and the abstract data 22 are allocated to different segments 51 and 52 in terms of management. Each document element data has its identification code. The data that is the root of the document is "DOCUM
It has an identification code "ENT" and an element name indicating the document type. In the article data, "article"
Element name. Also, it has a pointer to the content of the document, and the pointer points to the document element which is the first content element.

The document element includes a compound document element having contents inside and a character element at the end. The former is "NO
It has an identification code of "DE" and the latter has an identification code of "CHAR". The compound document element has a pointer to the next element, an element name indicating the type of the element, and a pointer to the content of the element. The element name of the first document element is "tit
"le", which has a pointer to the compound document element having the document element name "abtract" as the next element and a character pointer as the content. The character element has a pointer to the next element and a character code. The chain of pointers ends when the value of the pointer is "0". The processing procedure of this embodiment basically follows the flowcharts of FIGS. 5 and 6 shown in the first embodiment. However, the method of referring to and changing the storage destination is different from that in FIG.

In the step S601, whether or not the data has been referred to is checked to determine that the data is in the same segment before it is referred to, and when it is in the data of a different segment, it is determined to be already referenced. If it is not yet referenced, the process proceeds to step S602. In the separate storage here, a segment 53 is newly allocated, and the contents of the document element selected on the src side are transcribed therein. FIG. 11 shows a transient data storage state of the database at this time.

In step S603, on the src side, the pointer of the document element content is replaced with the data in the newly allocated segment 53. Also in step S604,
The pointer of the content of the document element selected on the dst side is replaced with the data in the newly allocated segment 53. FIG. 12 shows the storage state of the database thus replaced. If it is determined in step S601 that the reference has been completed, the process directly proceeds to step S604, and the pointer of the document content on the dst side is replaced. According to the present embodiment, there is an effect that the processing speed is improved by replacing the file with the memory image without using the file.

(Fourth Embodiment) In the third embodiment, an example in which each document is stored in a different segment and managed is described. However, even if the storage location is not changed in this way, the management information is stored at the beginning of each data. You may manage it by putting it on.

FIG. 13 shows a data storage form in which the management information 61 and 62 are added to the head of a set of data.

The processing procedure in this case is basically the same as that of the above-described embodiment. In the shared content independence process, instead of allocating a new segment, the management information 63 is generated, the shared content is reconnected here, and the src side and d
The document element on the st side may be pointed to the management information 63. The result is shown in FIG. In the present embodiment, there is no need to change the data storage location, and since sharing can be achieved by simply changing the pointers, the processing speed is further improved.

[0037]

As described above, according to the present invention,
Since the content of the document element is shared, if the shared part is changed in one document, the shared part in another document is also changed, so that the content can be changed while maintaining the consistency of the document.
