I would recommend to use developed and used already industrial 
standards to describe relational schema
In particular CWM (Common Warehouse Model) from OMG which is built on 
top of MOF
I had been using  it (my own implementation) for a few years in my 
relational DBMS <-> RDF ETL tool.
CWM is quite powerful to extend a wide set relational, OO, and XML 
schema (support of datatypes, integrity constraints, etc)
and quite flexible to extend it if you need features which are not 
included into the current version of CWM/
As far as I remember it is supported by (or they intended to support) 
Oracle products, IBM, Unisys, and other key players
