From the Google Wave Developer Blog:
To kickoff Federation Day, we open sourced two components: 1) the Operational Transform (OT) code and the underlying wave model, and 2) a basic client/server prototype that uses the wave protocol. The OT code is the heart and soul of the collaborative experience in Google Wave and we plan that code will evolve into the production-quality reference implementation.
The prototype is intended primarily as a simple “hello, world” implementation, to encourage experimentation using the Google Wave Federation Protocol. All of this code — nearly 40,000 lines of Java code — is available under the Apache 2.0 license, and we’ll be open sourcing more code as wave evolves. Check out the source code and get started with the introductory documentation.
