[Tm4j-developers] Graph presentation

[Jack P. <jac...@th...>]

It may be that this group is familiar with 
http://touchgraph.sourceforge.net. (Apache)
Another one I just discovered (though others may be familiar with it) is 
http://jgraph.sourceforge.net (LGPL)

An interesting point about jGraph is that it exports to GXL (Graph Exchange 
Language) http://www.gupro.de/GXL/

Which brings to mind an interesting set of issues.

For instance: the world seems to be awash in ontology expression languages, 
like DAML+OIL, OWL (just getting started), CG, RDF, XTM, and so forth 
(assuming you'll allow me to group XTM into that cluster).

One wonders if the persistence layer of any knowledge product ought not to 
consist of something a bit more "universal" (whatever that means) than 
XTM.  GXL comes to mind, and Murray Altheim seems to be heading in that 
direction. It may be that the GooseWorks package is going in that direction 
as well, but I'm not sure yet.

This would imply that the next generation of TM4J could be a wrapper/mapper 
for a GXL backside.  From the same backside, we could wrap/map to 
Conceptual Graphs, DAML+OIL, OWL, and who knows what else.

Your thoughts on the notion of going in the direction of a universal, 
graph-theoretic backside with wrapper/mappers?

Cheers
Jack
