306 | SNOMED CT Release Format 1 (RF1) Guide July 2012 4.3.1. Access to release information Terminology servers should enable client applications and users to access the current SNOMED CT release version information (3.2.8.4). 4.3.2. Access to components 4.3.2.1. Access to concepts A terminology server should enable client applications to rapidly find any Concept by any of the following criteria: • ConceptId; • SNOMEDID • CTV3ID Once a Concept has been found, the client application should be able to read the values. Any of the properties of that Concept included in the Concepts Table should be accessible. 4.3.2.2. Access to Descriptions A terminology server should enable client applications to rapidly find any Description or set of Descriptions by any of the following criteria: • DescriptionId; • ConceptId; • ConceptIdand DescriptionType Once a Description has been found the client application should be able to read the values of any of the properties of that Description included in the Descriptions Table. 4.3.2.3. Access to Relationships A terminology server should enable a client application to rapidly find any Relationship or set of Relationships by any of the following criteria: • ConceptId1; • ConceptId1, CharacteristicType and RelationshipType; • ConceptId1, CharacteristicType, Relationship group and RelationshipType; • ConceptId2; • ConceptId2, CharacteristicType, and RelationshipType. Once a Relationship has been found the client application should be able to read the values of any of the properties of that Relationship included in the Relationships Table. 4.3.3. Access to essential concept Identifiers Terminology servers should provide efficient access to the Identifiers that represent concepts with structurally significant Roles within the terminology. Table 236 lists the concepts that have the most clear-cut structurally significant Roles. A terminology server should enable access to these Identifiers by an easy to use name of enumeration. In addition a terminology server should provide a service that rapidly determines whether a given concept is a subtype of any of these concepts. It is also useful to for the terminology server to extend similar functionality to all direct subtypes of the root concept ( | SNOMED CT Concept |) and to subtype descendants of | concept model attribute |. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434

All other active concepts are subtypes of this concept. All active metadata concepts are subtypes of this concept. All enumerated values applicable to core components are subtypes of this concept. All reference sets and all reference set-related metadata concept are subtypes of this concept. All reference sets are subtypes of this concept. The Attribute used to specify the subtype Relationship between concepts. All Attribute (relationship type) concepts are subtypes of this concept. With the exception of the subtype Relationship (see above) all relationship types that are used in the SNOMED CT Concept Model are subtypes of this concept. Each subtype of this concept represents an extension namespaces allocated by the IHTSDO. Subtypes of this concept to provide nodes in navigation hierarchies. They act as grouper categories that do not have any semantic meaning and thus do not appear elsewhere in the SNOMED CT hierarchy. © 2002-2012 International Health Terminology Standards Development Organisation CVR #: 30363434
