Controlled vocabularies (also known as code systems or terminologies) are common information artefacts in healthcare. They allow for univocally and precisely referencing of concepts and are core foundation of any semantic processing of health data. In particular all electronic communication in healthcare relies on coded concepts for semantic interoperability and automated data processing.

The Object Management Group's Common Terminology Services Version 2 (CTS2) standard defines an accepted industry standard service interface to share, query and maintain value sets and other terminology artifacts. The CTS2 specification is structured within a platform independent model that provides two profiles:

1. Structural profiles define how code systems, associations, or value sets are organized;
2. Functional profiles define fundamental operations of persistent storage (CRUD) in an information system that change these structures.

One method to achieve compliance with the structural profiles of CTS2 is to use semantic web technologies that are widely used for vocabularies. In this way, CTS2 artifacts such as code systems, code system elements (i.e., codes and their designations), associations and value sets (i.e., sets of code system elements) can be processed with reasoning engines including code member validations. CTS2-LE follows that foundation. It relies on the Resource Description Framework Schema (RDFS) in conjunction with a schema vocabulary oriented towards the Frame Logic. So-called RDF signatures, based on this schema vocabulary, describe structural constraints according to the CTS2 information model. Likewise, arbitrary object graphs can be processed and stored with these RDF signatures.
