Abstract:
1. A method for managing document use in a system including a document management server that manages documents and a client that uses documents, the method comprising: receiving 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; 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.
