Field # Field Name Description Representation
1 MEDCINID MEDCIN concept ID MRHIER.CUI populated by the Metathesaurus CUI corresponding to MEDCINID.
2 NODEKEY Hierarchical identifier Used to construct the hierarchical tree position, MRHIER.PTR, for this concept. The "NODEKEY" value is a series of two-character tokens (some of which include a space character), e.g., " CDA D P" breaks down as "<space>C", "DA", "<space>D", and "<space>P", and removing the last token (yielding " CDA D", in this example) produces the "NODEKEY" value of this concept's hierarchical parent.
Also used to populate MRHIER.HCD.  Note that leading space characters have not been removed from the HCD value.

Field # Field Name Description Representation
1 MEDCINID MEDCIN concept ID MRREL.CUI1 populated by the Metathesaurus CUI corresponding to MEDCINID
2 RELATIONSHIPTYPE The SNOMEDCT CONCEPTID indicating the type of this relationship Mapped to corresponding values in MRREL.REL and MRREL.RELA. E.g., the "RELATIONSHIPTYPE" 123005000, which is the SNOMEDCT CONCEPTID for "Part of (attribute)", is mapped to REL = "RN" (narrower relationship) and RELA = "part_of".

If RELATIONSHIPTYPE = "168666000" (same_as), MRMAP.RRF and MRSMAP.RRF entries are also created.
3 SCT_CONCEPTID The SNOMEDCT CONCEPTID of the concept having the specified type of relationship to the concept indicated by MEDCINID MRREL.CUI2 populated by the Metathesaurus CUI corresponding to SCT_CONCEPTID
4 PREF_FLAG_ID 1=preferred, 0=non-preferred MRSAT.ATN = "PREF_FLAG_ID" (STYPE = "RUI")
