[topicmapmail] Conceptual Graphs are Step 6

Thanks for the kind comments, Dan.

It does seem to me that a discussion of such a specific topic as 
conceptual graphs in the context of topic maps is, at once, appropriate, 
and out of scope for this list. Go figure. I suspect this list is best 
served by thinking through implementations, applications, and so forth 
of just topic maps. OTOH, conceptual graphs are only slightly north of 
"just topic maps" as applications go. Bernard Vatant spoke at XML 2004 
on the marriage of topic maps and ontologies. I suspect we should be 
discussing that here too. It's really hard to tell what to do here. But...

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.

The black belts of the RM are pretty well nailed to the wall with a 
schedule that calls for finalizing the contribution the RM, in whatever 
final form it may take, to the topic map standards effort. That's all 
slated to happen in a workshop in Montreal associated with Extreme 
Markup 2004. I'd love to be there, but that's unlikely. The result of 
that workshop will be presented to the world, as I understand it, at XML 
2004 in Washington D.C. I am presently planning on presenting and being 
at that conference. Until we see the final form, it will be easier just 
to understand the nature of the conceptual graph architecture and sort 
out how topic maps and cg graphs blend.

Cheers,
Jack
