Apache Wave

Google Wave is the core of the former Wave project discontinued by Google.

Once taken offline from Google's services, the project was donated by the Google staff to the Apache Foundation, where development has continued since.

The Apache Wave project continued the work not only on the Google Wave Federation Protocol itself, but also provided a basic prototype server, complete with adjacent Web-based and console clients.

Just like the original Google Wave service, applications developed on Apache Wave work in near real-time, on distributed infrastructures and are ideal for group collaboration and chat applications.
