Description

Expected behavior

Characterizations should utilize the vocab daimon as defined for a CDM source to obtain concept name info.

Actual behavior

Characterizations instead try using the concept table within the cdm daimon.

Steps to reproduce behavior

Have a CDM source where cdm daimon != vocab daimon. Keep the cdm schema's concept table empty. Then run characterization with a feature like Condition Occurrence Any Time Prior. You'll see "Unknown concept".

Research direction

Start by reproducing the characterization with a CDM source whose cdm daimon differs from its vocab daimon and whose concept table is empty, using a feature such as Condition Occurrence Any Time Prior. Trace the characterization path that produces “Unknown concept”; done means concept name information comes from the vocab daimon instead of the cdm daimon.
