This list doesn't clog my inbox, so, what the heck, unless people ask us
not to discuss CG and topic maps, whether XTM, RM or whatever, then,
I'll contribute where I can. Perhaps the largest problem will be to
understand just what constitutes conceptual graphs for any kind of graph
larger and more complicated than the toys we can find on the web. I
think it was Murray who suggested that the CG standard doesn't go far
enough. I'm not prepared to comment. Murray and I both follow the cg list.
My only comment here is simply a reiteration of what I've said on
the CG list. Conceptual Graphs are more than FOL, but in any and
every attempt I or others have made to gain a picture of the under-
lying model for CG we are answered that it is "FOL". CGs are
demonstrably higher level semantics than FOL. The questions that
need answering for the CG community are remarkably similar to those
we've seen in the Topic Maps community: absent a conceptual model,
a data model, a processing model, etc. there cannot be any real
implementations of CGs, only inventions. This is not bad in itself,
but it's not really CG. There is no metric for "really" CG.
Until there is a CG standard that provides a complete explication
of what exactly a Conceptual Graph *is*, we can only steal ideas
higgledy-piggledy, like picking the good parts out of a salad. I
and others have repeated asked for a more complete CG specification,
but in response I've seen only avoidance of the question. I have
some hope that the Common Logic project will provide a low-level
logical framework (that could inform CG and perhaps provide a
better underlying architecture), but the higher-level semantics
of CG still need detailed models in a form developers can use.
