An Application Programming Interface (API) specification that is intended to describe the basic functionality that needed by healthcare software implementations to query and access terminological content. CTS2 defines the functional requirements of a set of service interfaces to allow the representation, access, and maintenance of terminology content either locally, or across a federation of terminology service nodes.
- CTS2 is specified as an API rather than a set of data structures to enable a wide variety of terminological content to be integrated within a common framework without the need for significant migration or rewrite.
- CTS2 was developed from the original the [see HL7 CTS specification] and is now a joint initiative between HL7 and the [see Object Management Group (OMG) ].
