Subject: Re: [emergency] GJXDM vs EDXL Distribution isses


Just to add my $.02 a bit further, I don't think there is much chance 
of us adopting a "not-invented-here" parochialism. Since a few of us 
are trudging through the entire GJXDM to discover what and where the 
differences are with the work we've done so far, I suspect that we 
will most likely recommend best practices for implementors to use the 
appropriate namespaced term.  To do that we must first do the 
diligence of comprehensive comparison so  we can then look at 
similarities, duplications and differences and make our 
recommendations.

And just to add a bit more, while I am keeping my mind open to 
alternatives, I suspect we will end up settling on the use of an 
ontological approach to making our recommendations: for uses in 
inontology/taxonomy x, use schema a, for uses in ontology/taxonomy y, 
use b, etc. I am personally in favor of using existing work whereever 
it doesn't require too many extensions to cover the requirements we 
have scoped for the particular piece of work.

Ciao,
Rex..
