The software is not yet documented or released (but will be soon, I hope). Some notes are at [1]. - one is based on ideas from Ian's paper. All test cases from [1] have been passed (except that I take a different approach to cardinality constraints). - the other is based on adding a "variable binding modifier" to conventional Horn-like rule. So far, my intuition is that Ian's GeneralRestriction class approach integrates more smoothly with general RDF -- the datatypes can be built into the software, and accessed/used within the RDF syntactic framework. I've yet to see how this plays out in a real application. #g -- [1] http://www.ninebynine.org/RDFNotes/RDF-Datatype-inference.html ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
