Google earlier decided to discontinue the Google wave service Google to Stop Google Wave. Later Google decided to make it a separate application "Wave in a Box". The product includes the following
an application bundle including a server and web client supporting real-time collaboration using the same structured conversations as the Google Wave system
a fast and fully-featured wave panel in the web client with complete support for threaded conversations
a persistent wave store and search implementation for the server (building on contributed patches to implement a MongoDB store)
refinements to the client-server protocols
gadget, robot and data API support
support for importing wave data from wave.google.com
the ability to federate across other Wave in a Box instances, with some additional configuration
Google is hosting a Wave Protocol Summit in San Francisco, November 8 – 12, 2010
The summit will be targeted towards technical people interested in using, contributing to, or building on Wave technology. Content will include:
technical talks on specific aspects of Wave technology,
problem solving around open technical issues,
discussions about project organisation and governance, and
group coding sessions (fun!).
The summit will be three days of talks and discussion (November 8 – 10) followed by two days of coding (November 11 – 12) on Wave in a Box and federation.
