We’re building some ETL tools and one of our developers asked the question if concept_id values in the concept table were consistent between iterations of the CDM Vocabularies. That is, for the same concept code, in different releases of the CDM vocabularies, is the same concept_id primary key value re-used?
Yes, a CONCEPT_ID in this release of the VOCAB will continue to be the same item in future VOCABs. They are not reused for other source codes.
