DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described.

FIG. 1 is a functional block diagram of a document search system 1 according to an embodiment of the present invention. The document search system 1 includes a document management server and a client connected to the document management server (neither is shown).

The contents of the document itself and information accompanying the document (such as document properties and folders) are collectively referred to as document information in this specification.

In the document management server, document information is managed hierarchically. Here, hierarchization has the following two meanings. -Position the document at the terminal node on the tree structure composed of folders. -It has a hierarchical structure such as version and element file as the internal structure of the document.

The document to be converted in the document search system 1 may be a document or a folder. In the case of a document, it is converted including its internal structure. In the case of a folder, all folders and documents below the folder are converted.

As shown in FIG. 1, the document management means 21
Manages document information that has version information inside the document.
The document management means 21 manages a document in three layers: a document, a version, and a stream.

[0038] Documents are further positioned in folders.
Since the folders have a tree structure, a parent folder exists except for the top-level folder. These data are managed as, for example, the following relational database.

The document serializing means 22 extracts necessary information from the document managing means 21 for a certain document or folder, and generates a serialized document text using the information.
If data is sent in binary format, the design of the data format is cumbersome and poorly extensible. Therefore, the document information is transmitted in a predetermined format in a text format. The conversion from the internal format of the document management means 21 of the document management server to the text in this predetermined format is called serialization. In this case, since program processing cannot be performed with simple text, data is expressed using XML (Extensible Markup Language).

FIG. 6 shows an example in which a folder having an ID of F002 is serialized when the document management means 23 has data as shown in FIGS.

In FIG. 6, <ListOfProp> and </ ListOfPr
The part between op> is the list of document properties. The name used for each property tag is
Equal to the field name in each table.

The part enclosed by <ListOfContent> and </ ListOfContent> is the element of the next hierarchy. A folder or a document is a folder, a version is a document, and a stream is a next layer in a version.

The part between <Stream> and </ Stream> contains a character string obtained by encoding the contents of the stream using Base 64 or the like.

The serialized document filing unit 25 generates directories and files on a file system based on the serialized documents. FIG. 7 shows an example in which the serialized document shown in FIG. 6 is converted into a file. The lower character string in each frame in FIG. 7 indicates the name of a directory or a file.

FIGS. 8 and 9 show processing procedures performed by the serialized document filing unit 25. FIG. That is, <Folder>, <Docume
<nt>, <Version>, <Stream>
The nt> element is associated with a file, and the parent-child relationship between directories matches the parent-child relationship of elements in the serialized document.
The name of the directory is used by concatenating the element name of the corresponding element and the value of the <ID> property. For example, a folder whose ID is F002 is named "Folder: F002". For the file name, use the value of the <Name> property of the <Stream> element. The properties of each element are stored in a file with a specific name (for example, '.properties', <ListOfP
rop> element is recorded as a character string.

By following the directory structure, the application can access a necessary part of the folder or the document. It is also possible to revise the contents of the document.

More specifically, as shown in FIG. 8, the serialized document is converted into an internal tree structure (step S1), and the highest node is set as the current node (step S2). Then, a node conversion process is performed (step S3).

The node conversion processing (step S3) is performed as follows. That is, as shown in FIG.
If it is not <Content> (N in step S11), a new directory is created in the current directory and set as the current directory (step S12). Then, the nodes under <PropList> are stored in the properties file as XML (step S13), and the first child node of the node conversion process <ListOfContent> is set as the current node (step S14). If the current node is <Content> (Y in step S11), a file in which the element content is decoded is created in the current directory (step S15).

After the processing in steps S14 and S15, if there is an unprocessed node of the same level (Y in step S16), that node is set as the current node (step S1).
7), and return to step S11. This is repeated until there is no unprocessed node at the same level (N in step S16).

The filed document serializing means 24 serializes the document developed on the file system in the reverse of the serialized document filing means 23. The procedure is shown in FIGS.
It is shown in FIG.

That is, since the name of a directory starts with one of 'Folder', 'Document', 'Version', and 'Stream', it can be determined which element of the serialized document the directory corresponds to. The hierarchical structure of the directory directly corresponds to the hierarchical structure of the elements in the serialized document. The file corresponds to the <Content> element of the serialized document. The file name is the "name" of its parent element (<Stream>)
Corresponds to the property.

Specifically, as shown in FIG. 10, the designated directory is set as the current directory (step S2).
1) Perform directory conversion processing (step S2)
2) Convert the internal tree structure to XML (step S2)
3).

Directory conversion processing (step S2)
2) is performed as follows. That is, as shown in FIG. 11, the current directory name starts with “Folder” (step S31) or starts with “Document” (step S3).
2) Start with 'Version' (step S33) or 'S
"Folder" node, "Document" node, and "Versio", respectively, depending on whether they start with "tream" (step S34).
Generate an 'n' node and a 'Stream' node (step S
35 to S38).

'Folder' node, 'Document' node,
When a 'Version' node is generated (step S35
To S37), read the '.properties' file immediately below, and generate a <ListOfProperty> node (step S3).
9) Generate a <ListOfContent> node (step S)
40). Then, the directory conversion process (step S22) is performed so that the first child of the current directory is set as the current directory (step S41).

When the 'Stream' node is generated (step S35), the '.properties' file immediately below is read, and a <ListOfProperty> node is generated (step S4).
2) Read a file other than '.properties' immediately below and generate a <Content> node (step S43).

After steps S41 and S43, if there is an unprocessed node of the same level (Y in step S44), the node is set as the current node (step S45), and the process returns to step S21. This is repeated until there is no unprocessed node at the same level (N in step S44).

The serialized document new registration means 25 is a means for registering a serialized document as a new document in the document management server. All IDs in the serialized document may be used in existing documents, so a new ID needs to be assigned.

Therefore, unused IDs are obtained for all the <ID> elements and recorded in the ID conversion table. That is, each <Folder>, <Document>, <Version>, <
For <Stream> element, extract properties required for record creation from <ListOfProp> child element and insert a new record in the corresponding table. At this time, the property whose value is ID is converted into a corresponding unused value using the ID conversion table.

The serialized document re-registering means 26 is a means for updating the corresponding original document using the serialized document.

That is, the record in the database is updated using the ID in the serialized document as a key. And each <Folder>, <Document>, <Version>, <Stream>
For the element, fetch the value of <ID> element from <ListOfProp> of the child element and search for records using it as a key. The field value of the record can be obtained by extracting necessary properties from the <ListOfProp> of the child element.

FIG. 12 is a block diagram schematically showing a hardware configuration of the document management system 1. As shown in FIG. 12, the document management system 1 shows the configuration of the client, and has a function of controlling each unit.
