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 Appendix B3 for a list of all term type abbreviations and their full names.
• See Appendix B.5 for a list of sources and their associated term types, listed in default order of precedence.
• See Section 2.7.1.3.14 of UMLS Documentation for more information on MRCONSO.RRF.
