Re: [Fwd: Language Ontology]

Hi Misha,

We are very aware of it, and have been following the work, but I failed 
to mention it in the email.  I should say that our ontology was 
developed for offline use in an internal system, as an initial 
requirement.  Having said that, if you look at the RFCs, they only 
describe tags, not an RDF vocabulary or OWL ontology.  Our approach is 
compatible with the RFCs but adds capabilities that support co-reference 
resolution, for example, in target application.

Best,

Elisa
