An association between a source concept and a destination concept.
Notes
- Each relationship is represented by a separate row in the relationship file.
Each relationship has a unique identifier and contains columns identifying the relationship type and the concepts that are related (sourceId and destinationId).
- Each relationship provides defining information about the source concept.
- Following enhancements to SNOMED CT during 2019, the authoritative stated representation of this defining information will be OWL axioms distributed in OWL Expression Reference Sets. Relationships will continue to be distributed to represent the necessary normal form.
Example
- The source, type and destination of one of the relationships for the concept 74400008 | Appendicitis (disorder)| are as follows:
sourceId | typeId | destinationId |
---|---|---|
