Similar conversions let XTM express Conceptual Graphs.  This page
from my CTM ontology shows a simple illustration:

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?
