Abstract

A structured document management system for managing a structured document is disclosed, the system including: an element registration unit for registering attribute information and content information about each of elements in the structured document as element information; a structural information registration unit for registering relations between the elements in the structured document as binary format structural information; and an information retaining unit for retaining the element information registered by the element registration unit as records of a relational database while preserving the binary format structural information registered by the structural information registration unit.

Claims

1. A structured document management system for managing a structured document, comprising:

an element registration part that registers attribute information and content information about each of elements in the structured document as element information;

a structural information registration part that registers a relation between the elements in the structured document as binary format structural information; and

an information retaining part that retains the element information registered by the element registration part as a record of a relational database while preserving the binary format structural information registered by the structural information registration part.

2. The structured document management system according to claim 1, wherein the information retaining part retains the structural information as a binary format file in the relational database.

3. The structured document management system according to claim 1, further comprising a decomposing part that decomposes an inputted structured document into plural partial structures according to predetermined settings while causing the information retaining part to register a relation between the partial structures as binary format structural information,

wherein the element registration part and the structural information registration part cause the information retaining part to register element information and structural information about each of the partial structures decomposed by the decomposing part.

4. The structured document management system according to claim 1, further comprising a difference analyzing part that analyzes a difference between each of the elements in an unedited structured document previously retained by the information retaining part on the one hand, and each of the elements in the newly edited and inputted structured document as a result of editing the unedited structured document on the other hand,

wherein the element registration part registers element information about any difference analyzed by the difference analyzing part;

and

wherein the structural information registration part generates and registers structural information including the difference.

5. The structured document management system according to claim 4, wherein the element registration part, if finding any element deleted by the difference analyzing part upon difference analysis, furnishes a record corresponding to the deleted element with version information in effect prior to the editing while generating an index reflecting the version information to arrange the element with no prior version information attached thereto to make up the most recent structured document available for a search.

6. A structured document management method for managing a structured document, comprising the steps of:

retaining attribute information and content information about each of elements in the structured document as a record in a relational database; and

retaining a relation between the elements in the structured document as binary format structural information.

7. The structured document management method according to claim 6, further comprising the step of retaining the structural information as a binary format file in the relational database.

8. The structured document management method according to claim 6, further comprising the steps of:

decomposing an inputted structured document into plural partial structures according to predetermined settings;

retaining a relation between the partial structures as binary format structural information; and

retaining element information and structural information about each of the partial structures decomposed in the decomposing step.

9. The structured document management method according to claim 6, further comprising the steps of:

analyzing a difference between each of the elements in an unedited structured document previously retained on the one hand, and each of the elements in the newly edited and inputted structured document as a result of editing the unedited structured document on the other hand; and

retaining element information about any difference analyzed in the analyzing step while generating and registering structural information including the difference.

10. The structured document management method according to claim 9, further comprising the steps of:

if finding any element deleted in the analyzing step, then furnishing a record corresponding to the deleted element with version information in effect prior to the editing while generating an index reflecting the version information to arrange the element with no prior version information attached thereto to make up the most recent structured document available for a search.
