SNOMED CT Snapshot OWL Ontology Reference Set

$179 / year

This dataset is an OWL (Ontology Web Language) 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 OWL ontology reference set enables the use of prefixes in the ontology.

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.

In addition to 623 new concepts specific for the US, the September 2018 SNOMED CT US Edition also contains all of the content from the July 2018 SNOMED CT International Edition. Approximately 543 requests for terminology additions and updates were submitted via the US Content Request System (US CRS) to support US clinical health information data exchange. This latest version of the US Edition also includes the SNOMED CT to ICD-10-CM reference set, with over 123,000 SNOMED CT source concepts mapped to ICD-10-CM targets.

NameDescriptionTypeConstraints
Reference_Set_Member_IdA field, uniquely identifying this reference set member. Different versions of a reference set member share the same ID but have different Effective_Date. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.stringrequired : 1
Effective_DateThe inclusive date at which this version of the identified reference set member became the current version.daterequired : 1
Is_ActiveThe state of the identified reference set member as at the specified Effective_Date. If active= true, the reference set member is part of the current version of the set, if active=false, the reference set member is not part of the current version of the set.booleanrequired : 1
Module_IdIdentifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date.integerrequired : 1 level : Nominal
Refset_IdIdentifies the reference set to which this reference set member belongs.integerrequired : 1 level : Nominal
Referenced_Component_IdThe identifier of the source component of the association. The concept to which the OWL expression applies. In the case of the 733073007 |OWL axiom reference set (foundation metadata concept)|, the axiom contributes to the definition of the identified concept.integerrequired : 1 level : Nominal
OWL_ExpressionRepresent essential information about an ontology. This information includes namespaces, ontology URI, ontology version URI, and import statements.stringrequired : 1
