Hi, All,
There's serious discussions going on concerning the IETF language tag subtag
registry and the ISO implementations of the 639 family of codes, so I think
it makes sense to coordinate any efforts in this direction with the folks
working on those two sets of standards. IETF 4647 spells out means for
matching codes, but it would make things a lot simpler if we have a more or
less standard format for representing them in rdf.
Bye for now
Sue Ellen
