SYNCHRONIZING ONLINE DOCUMENT EDITS

Online documents services are provided by application servers for editing by users. Documents are stored in component based structures in an application server's local memory to provide granularity in coauthoring and conflict resolution. Component level locking is utilized to minimize simultaneous user edit based conflicts and also to show presence of other users. Component based structure revisions are stored to capture component edits and synchronize upon document save actions. When edits are saved by one or more clients to the server, they can be saved to the current version of the server document, even if that document has changed from the version used to create the current representation on the client.
