A set of software functions that interface with and provide effective access to the content and features of one or more SNOMED CT editions.

Notes

• Each terminology service is a software function that interfaces with and provides access to information from one or more representations of a terminology.

• The software application that provides SNOMED CT terminology services is known as a SNOMED CT terminology server.
• While terminology services are applicable to several different terminologies, applications that provide SNOMED CT terminology services, should support access to the specific design features of SNOMED CT. These include the <i>subtype hierarchy</i>, <i>description logic</i> <i>concept definitions</i>, <i>reference sets</i> and <i>expression constraints</i>.

Examples

• Find a <i>concept</i> based on a set of search criteria. The criteria may include text to be matched against terms associated with the concept and constraints requiring a concept to be a subtype of an identified concept or a member of an identified <i>reference set</i>.
• Show the <i>preferred term</i> associated with an identified concept.
