But the initial question regarded a project where the implementation has been prototyped as a relational database. The tables thus far are not complex so any database implementation would do job currently. However, one of the project members expressed an interest in using XML and potentially topic maps. Since the schedule is tight and members wish to present at a winter conference, I have suggested that they continue working with the relational model and inquire as to the feasibility of exporting topic maps at a later time. If the topic map concepts are truly generalized, then exporting the properties and values of the relational tables, relationships, queries and scripting logic should enable such. Steve brings up the point that I do wish would be looked at seriously by other language communities: the potential of using property set/grove concepts to create information standards that are independent of lexical/syntax representation and implementation. As the VRML community is debating the concepts for the next generation of that language there is much discussion of a change towards context-free grammars and prototype based nodes (eg, the Balaguer paper). XML has been cited as an example to emulate. There exists an opportunity for different language communities to converge on common solutions. The cycles for creating or ammending standards are long enough and Internet Time cannot change that. Furthermore, the period that the W3C can be counted on to provide a stable base of languages given the current proliferation of consortia and interests is passing. If there is an opportunity to put the web language standards on common ground and open up the technical frameworks for a more competitive development environment, it should not pass without serious consideration.
