| Therefore I need an interface which maps SQL-statements (the queries
| which retrieve information from the relational data) into a list of
| "statements which create a Topic Map View".

I guess the first thing you need is a conceptual description of how
this is going to work, and there are many possible approaches that
could be taken.

I think you need to first of all answer some questions like:

  a) how directly should the resulting topic map reflect the
     underlying RDBMS? (Ie: do you expect to do normalization or
     create a simplified view; do you want to do string processing on
     values in the database, etc?)

  b) are you looking for a procedural approach (do this, then do that,
     then do like this) or a declarative approach (this table is a
     topic type; this table an association type; ...)

  c) do you plan to produce generic software, a running solution, a
     paper, or some combination of these?

What do you say?
