The question is a little ambiguous but what I understand is - you have a citygml file containing an example city that you have exported to rdf. - an ontology (say owl format) for CityGML standard.
If you want to link the two, simply add both to a model or tdb database. It will auto link. If however you want to create an ontology, then possibly look at http://cui.unige.ch/isi/onto//citygml2.0.owl which is one example I found from Google.
