]> I know how I’m going to support these multiple extensions in my own code. I’ll have the RDF model internally and map to it (XSLT for now), taking advantage of subclass/subproperty inference for dealing with the semantic differences between the different formats (as Suzan suggests). SPARQL will allow me to query across the diffferent properties out of the box. Best of luck to everyone else. 2005-06-29 Danny Ayers, Raw Blog - RSS extensions
