Kingsley, the OWL representation of the VistA schema is one of a number of
steps needed to round out FMQL - there's a rough list:
http://www.caregraf.org/semanticvista/fmql-specification#Profile

Right now, I need advise on the best way to demonstrate linkage such as the
above - a VistA data dictionary linked to standard dictionaries, VistA
Vitals -> SNOMED equivalents. VistA immunizations to CVX etc.

Are such standard datasets (SNOMED, RxNORM) in public end points already?
Where's a good list of what's available? I want to minimize local "mirrors"
- I've played with a few at http://www.caregraf.org/datasets and I could put
SNOMED etc in there but want to avoid any and all duplication.
