FWIW, I recently surveyed [1] papers from the last two iTrust [2] conferences on Trust Management in Open Systems [3,4]. The data is still very raw, basically N3, but the namespace prefixes and other header info aren't defined yet, but may be of some interest. Currently, there is a (quite low) level of semantic web awareness in this community, judging from the papers alone. [1] http://www.ninebynine.org/iTrust/iTrust-survey.n3 [2] http://www.itrust.uoc.gr/ [3] http://www.itrust.uoc.gr/conf2/ [4] http://www.trustmanagement.clrc.ac.uk/ The EU SECURE project [5] is also doing some very interesting work in this space -- they have a framework that maps a very theoretical logical framework to running code, all developed within the project. [5] http://secure.dsg.cs.tcd.ie/ I hope to post some notes of my own about this work in the not-too-distant future. I note they have also done some work on proof carrying assertions #g -- At 20:54 22/09/04 -0400, charles@w3.org wrote: >Josh wrote > > > ...There are many types of > > assurance -- some people might trust something based on the source > > domain name, others might require a PGP signature, and so on.
