Is there any overlap between FIXML and the W3 orgs work on a Resource Definition Framework (RDF)? How are the 2 related?

FIXML is the XML vocabulary based on the FIX Protocol. I’m no expert but as far as I understand it, RDF is the W3C recommendation called Resource Description Framework which addresses the issue of metadata (information about information) interoperability on the web. Its syntax looks something like:

There is also something called RDF-Schema which specifies information about classes in a schema. This has some simularities to something called XMI which allows you to express UML models in XML.
The effort we are most interested in is from the W3C’s XML Schema Working Group which introduces support for data typing in schemas.
For futher information on RDF, XMI, XML Schema, and any other XML buzzword I might have dropped, please consult the Robin Cover’s OASIS SGML/XML web page.
