Response from the Jini Community

Bill Venners: What response have you received from the community about the license model change?

Jim Hurley: The response from the Jini Community has really been fantastic. I'd characterize it as—excitement and anticipation. A couple notes to our users list have expressed this:

The screams of joy and acclamation are still echoing in my head and through the hallways.


Thanks to Sun for listening to your Jini team ;-), and congratulations to us all. That this may mark a new era for the Jini Technology and community!

The part I like best about the last one is "congratulations to us all!" It illustrates how the community was part of the overall process in determining the license change.

Bob Scheifler: That was definitely a critical part of this whole thing, openly working within the community to forge the right path forward. There was a lot of great debate and dialogue, and in the end, I think the entire community is psyched about the direction and possibilities.

Jim Hurley: We've made some important steps to enable this change, but there is still much to do. We've got to align our Jini Community Decision Process (JDP) [8], update our site [9] to make it an open source-style site, re-license Sun's other contributions (for example, Surrogate, Rio, etc) under the Apache 2 license, help projects who want to re-license their works, etc. This is all going to going to take a little time to work through, so stay tuned.

Bob Scheifler: Overall, we're very happy with the license model change. Freedom and choice win in the end, and we're really excited by the prospects of growth and technical advancement this brings to the Jini Community.

Talk back!
