Hi Sergey, 

you might be interested in the XML Metadata Interchange (XMI)
to adopt the names for your RDF-classes and -properties describing
an UML model. 

- http://www.oasis-open.org/cover/xmi.html
- ftp://ftp.omg.org/pub/docs/ad/98-10-16.txt


XMI 1.1 RTF Main revised document - OMG XMI 1.1 RTF. 25 October 1999.
OMG XMI v. 1.1: Revisions and Recommendations Summary. By: OMG XMI
Revision Task Force. OMG Document ad/99-10-02, 284 pages. "The main   
purpose of XMI is to enable easy interchange of metadata between
modeling tools(based on the OMG UML) and metadata repositories (OMG MOF
based) in distributed heterogeneous environments. XMI integrates three
key industry standards: (1) XML - eXtensible Markup Language, a W3C
standard; (2) UML - Unified Modeling Language, an OMG modeling standard;
(3) MOF - Meta Object Facility, an OMG metamodeling and metadata
repository standard. The integration of these three standards into XMI
marries the best of OMG and W3C metadata and modeling technologies,
allowing developers of distributed systems to share object models and
other metadata over the Internet."
