26. Namespace Naming Convention Proposal • Namespace URI:= BaseURI/SourceName/CMDate/SpecIDName • Namespace URI would be translated by a Namespace Resolver Service to translate • Down to a pointer to a registry interface to find resources or point down to a server. • Base URI:= (tbd)uncefact.org or uncefact.ebxml.org or ebxml.org or uncefact-oasis.org • Source Name:= (uncefact, (“/”,(UNBaseWG), “/”)| (oasis, (“/”, (OasisBaseWG), “/”) • UNBaseWG:= (TWG |ATG | Legal) • OasisBaseWG:= (MHS | RR | CPP) • CMdate:=yyyy-mm • SpecIDName:= (UnSubWGname | OasisSubTCname) • UNSubWGname:= (UMM, BPCMC, BPIMES, BRIM, BET, BCP, UEB, CBPC,…) • OasisSubTCname :=(tbd) • Unique ID:= Namespace URI + FilePath/FileName • A filepath and file name could lead to the location of resources. Or a Registry Object ID could allow discovery of the object from repository or provide URL to resource. • Namespace URI and “filepath and filename” are 2 distinct “thangs” which need XML mechanisms or registry mechanisms to help resolve to support discovery and use.
