Don't think so... No, there is not. However, Pat Hayes, at a semantic web interest group meeting in Cambridge a few months ago, talked about drafting a spec for a new version of RDF. And I think TimBL -- though I may be mistaken about who made the suggestion -- suggested that there be a way to indicate directly that two URIs name the same node of an RDF graph, which sounds like what you are looking for.
