| Similar conversions let XTM express Conceptual Graphs.  This page

| Your paper, Lars, contributed to my belief that the PSIs of CTM let
| compliant instances of Conceptual Graphs be expressed in *either*
| XTM or in RDF, with equivalent (PSI-defined) semantics.
| 
| Although the PSI pages themselves are not yet finalized, does this
| belief seem in principle to be correct?

I have to admit that my knowledge of Conceptual Graphs is very
limited, but your first 7-topic example would certainly be
translatable into topic maps directly, without benefit of any mapping
at all, since the structure matches that of topic maps.

If the 'Agnt' and 'Dest' concepts are predefined with a particular
meaning in CGs then I agree with you that defining PSIs for these let
this meaning be preserved in topic maps, and is part of what is
necessary to do a CG-to-TM conversion.

Have you tried actually writing a converter from a CG format? It would
be interesting to see if this could be made to work.
