Source and Term Types: Default Order of Precedence and Suppressibility - 2015AA 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.

Effective with the 2015AA release, MTH|MM is no longer assigned to Metathesaurus strings with multiple meanings and has been deleted from this list. Ambiguous strings are identified in the AMBIGLUI.RRF (AMBIG.LUI in ORF) and AMBIGSUI.RRF (AMBIG.SUI in ORF) files.

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 (Section 6) to change the selection of preferred names or to alter suppressibility.
