Sorry - I just flushed all of the Concepts right through without thinking about it (I'm interested in the tokens, not the relationships). It was no problem to throw out Concepts which are somebody's NT, now reduced from 2790 (!!) to 991 (!). Are "TopConcepts" really so important? I confess I stuck them in only because Norman had in his documents and I could just as easily leave them out. Presumably, your OWL tools determine top-edness automatically.

Don't speak OWL, so If someone will suggest a complete and standard OWL syntax for the entries, I'd be happy to automatically produce an OWL version / include OWL elements as well, as appropriate.

Good idea - memory is cheap but bandwidth is still limited.
Thanks for the this round of corrections. Any more?
