When mapping to reference terminologies (e.g., SNOMED, LOINC, ICD10, etc) we often just have the code within that reference terminology. For example, the Acute pain concept is mapped to SNOMED-CT 274663001
(name & description from SNOMED-CT is not copied into the mapping).
I don’t know what you mean by a concept reference term type. Reference terms are links to codes within external (often standardized/reference) terminologies. We link to the reference term by its code, but do not try to represent full detail of the reference term within OpenMRS (just reference it).
