HL7 international Provider Registry material

The HL7 international Provider Registry material was submitted for ballot in 2005, but is currently only has Draft for Comment status.

Comments that might be provided:
1. That the choice of which classes/attributes are tagged for updatemode and audit attributes looks arbitrary -- which it is, because the mapping was only intended to support the PRS object model. The model needs to be generalized.

2. More class and attribute level documentation is needed. We have raised the bar higher since this model was designed and should expect, at a minimum, to see a description and rationale for every single component.

3. The query models should be rationalized. The identifier search should be much leaner. The detail search should be tightened to require an Identifier - no fishing.

4. I suspect there are datatypes that need to be tightened up.

5. I would complain about the publication, which fails to supply a single xml or xsd example of the use of the extended attributes. (This was a publishing glitch that never got fixed.)
