Abstract

There is provided a document management server including a receiving unit that receives an access request and a first ID representing a document to be an object of the access request, an ID processing unit that issues, when an operation is performed on the document in response to the access request, a second ID corresponding to the operation, and records a derivation relationship having the second ID as a child of the first ID, an attribute recording unit that records attribute information relating to the operation by association with the first ID or the second ID, and a response data provider unit that provides, when the document is provided to the client in response to the access request, response data including attribute information associated with at least one ID appearing in a path from the received ID accompanying the access request to a root of a derivation relationship.

Claims

issuing, when an operation is performed on the document in response to the access request, a derivative ID, the derivative ID representing the document after the operation is performed;

adding a derivation relationship between the derivative ID and the received ID to the tree of derivation relationships wherein the added derivation relationship indicates that the derivative ID has a child relationship with respect to the received ID;

recording attribute information relating to the operation, the attribute information being associated with the received ID or the derivative ID; and

providing to the client, when the document is provided to the client in response to the access request, response data, the response data including attribute information associated with at least one ID appearing in a path associated with the added derivation relationship, the path being from the received ID accompanying the access request to the root ID of the tree of the derivation relationship but not including the received ID.

2. The method according to claim 1, further comprising:

recording control information that controls disclosure of the attribute information for each ID; and

wherein providing the response data to the client comprises controlling whether or not to include attribute information associated with at least one ID appearing in the path associated with the added derivation relationship into the response data in accordance with the control information.

3. The method according to claim 1, wherein:

the attribute information includes update information for the document or additional information added to the document; and

wherein providing the response data to the client comprises providing, in the response data, update information or additional information associated with at least one ID appearing in the path associated with the added derivation relationship and a document corresponding to the ID.

4. The method according to claim 1, wherein providing the response data to the client comprises obtaining a derived ID which is a descendant of an ID received together with the access request, and provides to the user response data including attribute information associated with at least one ID appearing in the path associated with the derived ID.

5. A document management server for managing document use comprising:

a receiving unit that receives an access request from a client and an ID representing a document to be an object of the access request, the received ID being a descendant of a root ID of a tree of derivation relationships;

an ID processing unit that issues, when an operation is performed on the document in response to the access request, a derivative ID, the derivative ID representing the document after the operation is performed;

said ID processing unit adding a derivation relationship between the derivative ID and the received ID to the tree of derivation relationships wherein the added derivation relationship indicates that the derivative ID has a child relationship with respect to the received ID;

an attribute recording unit that records attribute information relating to the operation, the attribute information being associated with the received ID or the derivative ID; and

a response data provider unit that provides to the client, when the document is provided to the client in response to the access request, response data, said response data including attribute information associated with at least one ID appearing in a path associated with the added derivation relationship, the path being from the received ID accompanying the access request to the root ID of the tree of the derivation relationship but not including the received ID.

6. The document management server according to claim 5, further comprising:

an information control unit that controls disclosure of the attribute information for each ID; and

wherein the response data provider unit controls whether or not to include attribute information associated with at least one ID appearing in the path associated with the added derivation relationship into the response data in accordance with the information control unit.

7. The document management server according to claim 6, wherein the information control unit specifies a disclosure condition for the attribute information recorded in association with the ID.

8. The document management server according to claim 6, wherein, the information control unit specifies a disclosure condition for attribute information recorded in association with a descendent ID in a path of a given ID.

9. The document management server according to claim 6, wherein the information control unit specifies a disclosure condition for attribute information recorded in association with at least one ID appearing in the path associated with the added derivation relationship.

10. The document management server according to claim 5, wherein:

the attribute information includes update information of the document or additional information that is appended to the document;

the response data provider unit provides response data that includes update information or additional information that has been associated with at least one ID appearing in the path associated with the added derivation relationship and a document corresponding to the ID.

11. The document management server according to claim 5 further comprising:

an information control unit that controls whether or not to permit an update or an addition of additional information to the document at an ID appearing in the path associated with the added derivation relationship; and

an update control unit that controls so as to prohibit an update or an addition of additional information to the document when there is an ID that prohibits the update or the addition of additional information to the document in the path associated with the added derivation relationship.

12. The document management server according to claim 5, wherein:

the attribute information that is associated and recorded with the ID includes document data of an updated version obtained as a result of an update operation on the document; and

the response data provider unit provides response data including document data of the updated version associated and recorded with an ID appearing in the path associated with the added derivation relationship.

13. The document management server according to claim 12 further comprising:

an information control unit that specifies which one of an original and at least one updated version of the document to be provided to the client in association with an ID in the derivation relationship; and

wherein the response data provider unit selects one of the original and at least one updated version of the document that has been associated with an ID appearing in the path associated with the added derivation relationship according to control by the information control unit, and incorporates the selected document into the response data in the response data.

14. The document management server according to claim 5, wherein:

the response data provider unit obtains a derived ID which is a descendant of an ID received together with the access request, and provides to the user response data including attribute information associated with at least one ID appearing in the path associated with the derived ID.

15. A non-transitory computer readable medium storing a program causing a computer to execute a process for document management, the process comprising:
