Well, along these lines I hope to publish at least two topic maps. I
have already completed the first:

  1. a topic map containing all of the Cyc upper ontology, with 
     subject indicators pointing to the Cyc online web pages.
  2. a topic map representing the Cyc upper ontology relationships
     intact. This is significantly more ambitious than #1. I'm about
     75% complete on this one, but have hit a few problems (such as
     how to represent Cyc variables). I'm working with Cycorp on
     this and other problems. 

I hope to be able to publish both topic maps via TopicMaps.Org as a 
White Paper or Technical Report later this Spring.

I'm also working toward publishing a US Library of Congress subject
headings topic map. This would provide over 320,000 subjects as 
according to a particular publication date of the US LoC listings
(which evolve over time). This latter project will follow on after
the Cyc project.
