I think it does, since we have a very simple set of rules to extend the 
input RDF. However, I guess it depends on what we (or rather you, as 
you're doing all the hard work ;-) want the format for the base document 
of the thesaurus to be. If it's easier to work with a simple text file, 
and then post-process that to create the RDF version, then it may be 
better to make these additions at that stage - ie go from

   simple text document
   -> simple text document + automatic clean up
   -> RDF, N3, HTML, ...

An advantage to the cwm approach is that we don't need to worry about 
parsing, we can just concentrate on the logic. Some disadvantages are 
that cwm can be painful to install, the syntax for the rules is not 
standardized, and it can be awkward to do what appears to be simple 
operations.
