I have been looking into utilization of UCUM to indicate units within N3C. I read many of the entries here on the forum, looked at Athena, and the OMOP specification. As such I was aware that UCUM was being used, not cached / downloaded and there were some maps for Medications in Athena. it was not until this am when I located this resource:
That my many questions about implementing UCUM on OMOP were answered. However, I do have a couple of unanswered questions based on my UCUM Odyssey…
- Do or how do other OMOP implementations store conversion(s) from source data to an set of implementation-specific canonical UoMs?
- What (if any) bearing do the CIEL maps to UCUM have for the N3C implementation? Is this related at all to my question (1) above?
- How do OMOP implementations resolve the curly braces? Is this done on a per implementation basis?
Many thanks in advance for your assistance!
