<description
value="The OMOP concepts for each column of the DMv1.2 visit table, from the DM → FHIR → OMOP crosswalk. Each target's comment names the OMOP CDM field it fills. `equivalent`: the column's own concept; `narrower`: one of several concepts the column's values map to; `relatedto`: a value, unit or qualifier concept. Concept IDs of 2000000000 and above are PROTECT-CHILD custom concepts (CodeSystem ProtectChildOmopVocabulary)."/>
