Future of P3P Workshop

November 13, 2002

P3P: Next Steps

Thanks to everyone who participated for a great workshop! We had some very useful discussions and got a good sense of the areas where there is interest in additional work. Rough minutes will be sent to this list soon and a summary report should be ready in mid-December.

The following is the list of areas for future work that we identified and prioritized during the closing session. I have indicated the names of the people who volunteered to write up a 1 page proposal on each of these areas. Please include purpose, scope, resources, and time frame and send your proposals to this mailing list by Dec. 13.
