Non RDF-based semantics

I am new to this thread.

I would like to know if there exists at least one w3c group [hence has a forum] currently working on non-RDF representations / implementations of a semantic web.

No offense to people who follow the XML-based data/information representation, but I have set up an [universal?] ontology, corresponding vocabulary, syntax/syntagm and semantics that allow describing anything - in any language, and that might be an alternative. At the same time I would want to write RFC(s)

Could anyone aware of such effort provide pointers, etc.

Thank you very much.
