In principle, if not properly resolved, the two alternatives produce different kinds of errors for http clients. The first would produce "Address not found" and the other "File not found". If one of those provides more robust error management at either resolver or client(e.g. reporting, tracking down the correct GUID, etc.), that one would be preferable. Not that I can see any relevant difference...I just offer a criterion that might affect choice.

And if we prefer a central service, should we just use DNS and assign subdomains for the individual services, e.g. http://rbgk13.tdwg.id/543-544-cfjf3f667 or assign paths within the URL to services, e.g. http://guid.tdwg.org/rbgk13/543-544-cfjf3f667 ?
