This material seeks to establish an international framework for the development of an application programming interface (API) that can be used by messaging software when accessing terminological content. It is not intended to be a complete terminology service in and of itself. Health Level Seven (HL7) Version 3 (XML-based) standards are based on a reference information model (RIM) which is flexible and general in structure. Representation of information within this model is dependent on the availability of terminological resources which can be used to populate the properties of the model with appropriate semantic content. Whenever possible, the HL7 Version 3 standard references existing terminological resources instead of attempting to create a new resource within the standard itself. Because exernal terminological resources can vary considerably in both content and structure, the CTS identifies the common functional characteristics that an external terminology must be able to provide. As an example, an HL7 compliant terminology service will need to be able to determine whether a given concept code is valid within the particular resource. Instead of describing a table keyed by the resource identifier and concept code, the CTS specification describes an application programming interface (API) call that takes a resource identifier and concept code as input and returns a true/false value. Each terminology developer is free to implement this API call in whatever way is most appropriate for them.
