Hell All!    (01)

Thanks very much for the stimulating reading! I was in meetings most of 
yesterday, but just spent some time with my morning coffee pondering the 
many deep thoughts to be found in this thread.    (02)

I have more research to do, but you have certainly given me quite a bit to 
start with. I will say that most modern taxonomies are not strictly 
hierarchical, but use facets that allow property sets to be defined that 
can be applied to information objects (at least in my world). Although the 
facets have typical thesauri relationships (Broader Than, Narrower Than, 
Related To, etc), the taxonomy as a whole does not need to have a strict 
hierarchical tree structure. Thus, no facet is "more important" or nested 
under another.    (03)

As an example of this, see the NASA taxonomy  http://nasataxonomy.jpl.nasa.gov    (04)

Although the taxonomy is very broad in nature, it is meant to act as a top 
level brokering layer, and as such, has functioned very well for us as we 
develop Center vocabularies that are domain specific, but need to be 
integrated into a larger point of view.    (05)

Once again, thanks very much to you all. I will continue to listen and 
learn from all of you.    (06)
