In the long run, I want Nexist to be based on open standards. If you want a topic map from it, you get it in XTM. If you want an ontology, you get that in DAML/OIL. There exists, however, an open question: is there some canonical way to represent everything in the database such that it can come out any way you want it? The idea being that you apply some transcoding scheme (i.e. XSLT) to some canonical "document" (Douglas Engelbart calls this an "iFile") to get the representation you want. Cheers, Jack |
