are you familiar with



http://www-db.stanford.edu/~melnik/rdf/fusion.html ?

The idea of interpreting arbitrary XML documents semantically is at
least as old as RDF exists, I think. Unfortunately, quoting Brian on
this, "there ain't no free lunch". Assigning "meaning" to random XML
will often produce conterintuitive interpretations, unless the author of
the document cooperates and uses XML markup judiciously. The above links
suggest some ways of "adorning" XML documents (even as non-intrusively
as by simple DTD modifications) so that the corresponding documents have
well-defined RDF mappings. A reference implementation exists since 1999.
