Notes

  • A term type indicates the role an atom plays in its source
  • An atom is the smallest unit of naming in a source; that is, a specific string with specific code values and identifiers from a specific source.
  • Every atom has a separate row in MRCONSO.RRF. Every atom is assigned a term type.
  • Term types are assigned based on source documentation or NLM understanding of the source.
  • Sample data are provided for every term type in the source (see below).
  • See Metathesaurus Documentation for a list of all term type abbreviations and their full names.
  • See Metathesaurus Documentation for a list of sources and their associated term types, listed in default order of precedence.
  • See Section 2.3 of the UMLS Reference Manual for more information on terms and term types in the UMLS Metathesaurus.
