Syncro - Concurrent Editing Library for Google Wave
The web accelerated the way people collaborate globally distributed. With Google Wave, a rich and extensible real-time collaboration platform is becoming available to a large audience. Google implements an operational transformation (OT) approach to resolve conflicting concurrent edits. However, the OT interface is not available for developers of Wave feature extensions, such as collaborative model editors. Therefore, programmers have to implement their own conflict management solution.
This paper presents our lightweight library called syncro. Syncro addresses the problem in a general fashion and can be used for Wave gadget programming as well as for other collaboration platforms that need to maintain a common distributed state.
