I tried something similar a couple of years ago, though not specifically
with classes of XML document. I built some RDF schemas to allow me to map
data in flat files to EDIFACT EDI elements. The idea was to be able to
reduce to a minimum the amount of translation our software had to do when
processing files (just in time and just enough) which might or might not be
physically EDI. Mappings can be quite complex, it is often not enough to say
that field x is equivalent to element y, you quite often end up with things
like "sum of all field x within structure z is equivalent to element y", or
"if field n has value foo field x is equivalent to element y". You can even
end up with mappings which depend on the contents and structure of other
documents to establish equivalence. Context, be it local or global, is so
important.

All the best

This is an interesting idea. I've been pondering it over a few days
with a friend of mine, Damian Steer, who isn't on these lists. He
suggested that you might be able to use RDF to point into XML schema
documents and say things like thisTag is equivalent to
thisOtherTag. You could point into XML schemas in RDF using Xpointer (as
I know EARL are doing for XML instance documents). RDF schema itself
doesn't enable you to say that classes are equivalent, but the DAML work
extends RDF to be able to do this.
