LexEVS and its data model LexGrid comprise a full function terminology service meeting a wide range of requirements. The Common Terminology Service 2 is a comprehensive standard defined by a broad range of community interests.

  • The LexEVS 6.5.1 implementation updates internal framework to include asserted value sets when querying for resolved value sets.

The URI Resolver

Given the RESTful nature of CTS2 along with the possibility of distributed queries over multiple terminology nodes, the need for canonical naming conventions around URI, IRI or URL becomes paramount.  To serve this purpose a URI resolving service has been built for CTS2 over LexEVS.  This service attempts to provide a canonical name in the form of a URI based on curated convention and dependent upon the comprehensive storage of know other URIs known for a given terminology.   As such this service provides some securely robust resolution of a given resource despite it's possible use of an alternative URI.
