RDF is _NOT_ built on top of XML. Thinking that it is causes a lot of trouble in the architecture of big RDF projects. RDF is a data model, not a serialisation. The data model is also a graph (more than XML can cope with) and can span multiple documents. It's only RDF/XML that's the serialisation of RDF into XML and good architectures start from thinking about the RDF data model, not this RDF/XML serialisation. As to RDF handling, then the usual toolset is Jena (in Java) and Redland has a Python binding although Redland is fairly aged now. I'm unfamiliar with XMP and won't have a chance to look at it until Monday. However if XMP is strongly "XML like" despite claiming to be RDF, then you might find that handling a pure XMP problem is quite easily done with XML tools. Famously RDF/XML is unprocessable with XSLT if it's sophisticated, but quite easy if it's restricted to only a simple XML-like RDF model. XMP could well be similar. -- http://mail.python.org/mailman/listinfo/python-list
