Dear Ed, (01)
EB> Matthew's idea that an organization should be the authority for terms

the

MW: Well in the Process Industry ISO TC184/SC4 is trying to do this through
the ISO 15926 Reference Data Library (RDL), where industry level classes are
identified, defined, and given URIs.

an

> mature enough to have an authoritative version of either. (03)
MW: Whilst ISO is where the standardisation takes place, it is of course
industry associations that develop the RDL. (04)
