A 762676003 |OWL (Ontology Web Language) expression type reference set| associates description logic statements with SNOMED CT concept in the OWL functional syntax. The SNOMED CT International Release contains two reference sets that follow the 762676003 |OWL expression type reference set| pattern:
– The 733073007 |OWL axiom reference set (foundation metadata concept)|, in which the OWL expressions represent and axioms that form part of the definition of the concept identified by the referencedComponentId.
– The 762103008 |OWL ontology reference set (foundation metadata concept)|, in which the OWL expressions represent essential information about an ontology. This information includes namespaces, ontology URI (Uniform Resource Identifier), ontology version URI, and import statements. The 762103008 |OWL ontology reference set (foundation metadata concept)| enables the use of prefixes in the ontology.
SNOMED CT (SNOMED Clinical Terminology) provides a common language that assists with the electronic exchange of clinical health information. It enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care. SNOMED CT Can be mapped to other coding systems, such as ICD-10, which helps facilitate semantic interoperability.
A Snapshot release contains the most recent version of every component released up to the time of the snapshot. The version of each component contained in a snapshot is the most recent version of that component at the release time. The ‘Snapshot’ release is useful for a simple installation but does not provide a history or retrospective view of the terminology. There are valid use cases for each Release Type. Each International release will incorporate all three of these Release Types, allowing users to choose the most appropriate format.
