What's New in LexEVS 6.1 (Includes CTS2 Compliant API)

CTS2 Compliance

Standards for terminology service interoperability have long been a goal of standards organizations. With Common Terminology Services Release 2, two standards organizations, Health Level 7 and the Object Management Group have jointly released both a comprehensive standard and a specification and done so under a structured operating agreement designed to provide workable standards to the community of users. At the same time, as a single Java API, LexEVS has become perhaps the most comprehensive terminology service API in the ontology world. This release of LexEVS focuses on wrapping a CTS2 compliant REST service over the LexEVS API. This CTS2 compliant wrapper provides core support of the Common Terminology Service - Release 2
