Loading from UMLS RRF (Rich Resource Format) Files
The Unified Medical Language System regularly releases a set of terminologies in a large set of files referred to as the UMLS Metathesaurus. LexEVS can load individual files from this file set using the LexEVS UMLS Batch loader.
We briefly mention the UMLS Metathesaurus tools on this page. Since all documentation for these is maintained at the website linked to below we won't repeat it here. As well LexEVS has a special purpose RRF loader which loads an NCI version of an entire MetaThesaurus. This is dealt with in the documentation for the NCI loaders and we won't repeat it's use here.
