Subject: Re: [PartyId "type" negotiation]
Prasad Yendluri said "If one party uses arbitrary partyId 'type' (for their own partyId), the receiving party may not have the framework to verify the Id to be a valid one per the 'type' (say DUNS)." Why would you need to validate the DUNS of your potential trading partner at all? Wouldn't the registry have done that when the CPP was registered? For example, why would a registry knowingly allow someone to use General Motors' DUNS in a CPP unless the registrant were known to be General Motors? You should be able to trust the CPP belongs to whom it purports to belong to, and the registry has a vested interest in ensuring so. Assuming I trust the registry, I should be able to trust the CPPs contained within it. If a "registry" of the decrepit old EDI model - say, Sterling Commerce - tells me that Roadway Express is accessible on their network using either SCAC "RDWY" or DUNS "006998397", then I can trust them. If my ISA says send this EDI interchange to whomever has the SCAC of "RDWY" I want that data only to go to Roadway Express in Akron, Ohio. Can't ebXML do the same? William J.
