Semantic Web using Magritte

I was wondering if anyone tried to do any kind of XML mapping using Magritte. I have the requirement to generate RDF from my business objects, so I was thinking of ways to simplify this. My idea was to add something in the Magritte descriptions for each object that pointed to the appropriate URI and schema. This may be more trouble than its worth. I suppose anyone who has done anything with generating XML from Magritte could maybe provide some insight on any hurdles they faced, design ideas, etc. I also am looking at Magritte for simplifying XML serialization in general. My problem overall is that I have to generate all these formats (XML for web service, RSS, ATOM, RDF) and I do not want to have to write a complex parser to even do this 1/2 way dynamically. Are there any other libraries out there that do this already? For instance, I did notice that there is that library (name escapes me) that lets you port your objects between Smalltalk versions by dumping to XML files, so that is somewhat close to what I need to do. I am thinking since I already have a large number of Magritte descriptions, I might as well expand upon that. This will also let me do things like change a schema dynamically and provide easy access memento objects to do things like create a preview of whatever format I am trying to produce. Thoughts?
