Policy Aware Web Meeting, Day 2

Day two of the Policy Aware Web face-to-face meeting ended up about as I expected. Over the last year, we have been able to show that policies and logical proofs can effectively be used to control access to Web resources between two parties. This year, we are moving on to the more interesting three- and four-party scenarios.

In short, we want to allow a policy to allow very non-technical Web users to be given access where their relationship to the content is proven by a logical proof constructed of elements from other, more technical, sites. We have to allow everyone's grandmother to play.

I'll have the new use case up shortly, but for now it is given in the meeting notes.

Tim Berners-Lee showed off his Tabulator at the PAW meeting, proving once again that he is not only smarter than the rest of us, he is also more productive. The Tabulator is very, very cool. It is a 100% javascript application to navigate and display Web-based RDF content to the point where it grounds in the traditional Web. It also allows searches within multiple identified RDF sources. Tim's vision of the Semantic Web is simply more clear than mine and it continues to impress me.
