What about XML Schema?

One of the things I was thinking about for XMLForms for Webware was a means of
mapping data model descriptions to RDBMS tables. Having worked on the task of
getting "normal" database systems to act like "multivalued" database systems in
recent years, I can say that the theory of mapping the models is fairly
straightforward; the killer in that work was getting queries working generally,
but that isn't a concern with MiddleKit.

I think that DbDOM is just RDBMS-based persistent storage of document trees; if
it is, then that really isn't so interesting, especially if you then want to
issue SQL queries on the database to find meaningful patterns of information.
I'll take a look at the link, though.
