Zusammenfassung:One embodiment of the present invention provides a system that controls accesses to revisions of documents in the presence of a multi-user permissions and ownership model. During operation, the system receives a request to on behalf of a user to access a revision of a document. If the request is directed to a most-recent revision of an existing document, the system uses the multi-user permissions and ownership model to control access to the revision. Otherwise, if the request is directed to a previous revision of the document, the system grants access to the revision only if the user was the owner of the document at the time of the revision.
