Hi Heath, Just analysing OIDs vs. URIs:
Usage: OIDs are in use in health informatics and other areas. URIs are in use everywhere in form of URLs Procesing: OIDs lack internal processing URIs can be processed Compatibility with actual identifiers: Inside archetypes, each node can be identified by a path, so if we use URIs to identify an archetype, just appending the path to the URI we get a valid URI to identify a node inside the archetyp. I go with URIs. -- Kind regards, Ing.
