Hello, we are implementing a C# RDFa parser available as webservice http://rdfa.informatik.uni-freiburg.de/parse?url= (running under Mono 1.9 which seems to have problems with threads, so it serves only one request a time). As it is work in progress the library is not yet online but is going to be published. We're also working on a Semantic Wiki with RDFa, everything is linked on <http://rdfa.informatik.uni-freiburg.de>. To test our parser, you can use a modified test harness which allows a one-by-one testing due to the abovementioned mono problems.
