[om-list] The Semantic Web

[Luke Call]

These are both very interestint. After an admittedly quick look I 
decided they both might serve as a useful data collection resource for 
OM if it gets off the ground. But they can't *be* OM, since as far as I 
can tell they can't meet all our requirements. While they might be able 
to represent the data, I want to represent it in a form that a program 
can basically traverse without having to load the whole thing at 
once--allowing simulations, etc. etc as the requirements suggest. 
Correct me freely...
