Source and Term Types: Default Order of Precedence and Suppressibility - 2023AB Release

This Appendix displays the default order of Source|Term Types and suppressibility as set by NLM and distributed in the Metathesaurus® in MRRANK.RRF or MRRANK in ORF.

Users are encouraged to change the order of Source|Term Type precedence and suppressibility to suit their requirements. The default settings will not be suitable for all applications. The highest ranking Source|Term Type within a concept determines the preferred name for that concept. Use MetamorphoSys to change the selection of preferred names or to alter suppressibility.
