titleEVS Vocabulary Processing

EVS licenses and serves third party terminology as needed to meet NCI and caBIG requirements. These vocabularies come to EVS from a variety of sources and in a variety of formats. Though the LexBIG application is able to import most of these formats directly, a few terminologies require further processing before they can be loaded. Details on terminology sources, formats and processing are provided on this page.

External vocabularies published by EVS

EVS makes available a number of terminologies through the NCI Browser and API that are produced by sources outside the NCI.

UMLS subsets published by EVS
