UCUM terminology subset in OMOP-is this a valid construct?

This is a valid idea, and it has been discussed. @Vojtech_Huser has a proposal along that line. We just have to execute and implement it.

Exactly. That’s missing. The other missing piece is to collect the right unit(s) for all applicable Measurement concepts. Before we can do that, we need to clean up the Measurement concepts.

If this all sounds like a lot of work - it is. :frowning:

Yes please.
