A set of one or more axioms that partially or sufficiently specify the meaning of a SNOMED CT concept.
- Concept definitions are represented in two ways in SNOMED CT release files:
- Concept definitions include two distinct elements
- Prior to July 2018 the stated view of concept definitions were represented by relationships in the Stated Relationships file. During a transitional period between July 2018 and July 2019 the OWL reference sets were introduced. Since the end of that transitional period in July 2019, the stated relationship file is no longer maintained or distributed. More information on the earlier representation of the stated view is provided in a historical note on Representation of the Logical Model - Before July 2018.
