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.
