Dear all, compact policies in P3P 1.0 were added in the last minute. They were very controversial but still made it into the 1.0 Recommendation. Now we have the new discussion about the compact format. This new discussion war triggered by feedback from web-site implementers and by feedback from 2 P3P workshops. In fact, by aggregating the whole rather complex structure of a full P3P Policy into a set of simple tokens with no relationship to each other, the assertion made by compact policies can get inaccurate from blurry to heavy overstatements. We discussed and offered to discuss the performance implications many times. With known-hosts we make asynchronus evaluation even easier. We offered to work on enhancing the compact format to give it at least 'some' structure, but there was no interest. Now the time has come to deprecate compact policies and to throw that burden over board. This means, Web-sites can still put up some tokens to make some P3P 1.0 agents happy, but the basis for semi-automatic decision-making in P3P 1.1 will be only based on the full XML format. At least, this is my suggestion. Best, -- Rigo Wenning W3C/ERCIM Policy Analyst Privacy Activity Lead mail:rigo@w3.org 2004, Routes des Lucioles http://www.w3.org/ F-06902 Sophia Antipolis
