EVS is transitioning from using Apelon DTS software for terminology services to using the open-source LexBIG software, developed by the Mayo clinic. The DTS vocabularies are available through the deprecated caCORE 3.x api. The LexBIG vocabularies are available through the evsapi 4.x. Because of the different processing requirements and availability of import formats, the release versions of DTSRPC and LexBIG data will not always be parallel.

To remain consistent with our historical practice of running only the previous version of the EVS technology stack in deprecation, the EVS team will be retiring the EVS 3.x caCORE APIs and the EVS 3.x Grid Services at the release of EVS 5.0 (tentatively scheduled for 2^nd Quarter 2009).  The DTS Terminology Server and Metaphrase Server will be decommissioned as they are replaced by the LexBIG terminology server as the underlying terminology server for EVS.  Additionally the NCI Terminology Browser and NCI Metathesaurus Browsers will be decommissioned and replaced with the NCI BioPortal Browser.  If you have not done so already we encourage you to begin planning your migration path to utilize a version later than 3.x of the EVS APIs and Grid Service, at the minimum EVS 4.1.   Below is a list of EVS products that will be decommissioned at the release of EVS 5.0.

If you have questions or concerns about the retirement of the NCI Terminology Browser or NCI Metathesaurus Browser please email us at ncicb@pop.nci.nih.gov.
