Property/Qualifier(s) Description Representation
concept name Concept preferred name MRCONSO.STR
TTY = PT
CODE = concept/code
concept code UMDNS Code MRCONSO.CODE,SDUI for associated "PT", "ET", "SY" and "HT" atoms.
Synonym
Association to synonymous term MRCONSO.STR
TTY = SY
CODE = concept code
Entry Term
Association to entry term MRCONSO.STR
TTY = ET where Term Device Type = "Device is a SEE reference."
TTY = RT where Term Device Type = "Device is a USE MORE SPECIFIC TERM entry."
CODE = concept code for TTY = ET
For TTY = RT, CODE values were imported from an external value.
MRREL.REL
An RO relationship is created between same-code ETs and PTs
An "RN/RB" relationship is created from an RT to each related concept
DEVICE_TYPE DEVICE_TYPE value is used to assign TTY; original value is also represented as an attribute CATEGORY EXPANDED BELOW entry with SEE ALSO references: TTY = PT
CATEGORY EXPANDED BELOW entry: TTY = PT
Device has SEE ALSO references: TTY = PT
Hierarchical Term: TTY = HT
Main Device Term: TTY = PT
NIR entry: TTY = PT

MRSAT.ATN = DEVTYPE (STYPE = SDUI)
Term Device Type Term Device Type value is used to assign TTY for Entry Terms; original value is also represented as an attribute Device is a SEE reference: TTY = ET
Device is a USE MORE SPECIFIC TERM entry: TTY = RT

MRSAT.ATN = DEVTYPE (STYPE = AUI)
DEFINITION
Definition_Status
The "DEFINITION" property contains the UMDNS definition value.
The Definition_Status qualifier qualifies the "DEFINITION" property.
MRDEF.DEF. Only definitions with the status "Releasable" are included in the UMLS Metathesaurus.
RELATED_DEVICE Relationships between concepts MRREL.REL
REL = "RO"
defining_concept "Parent" concept Used to build hierarchy (MRHIER.RRF)
Term Code in Source Code of Term MRSAT.ATN = TERM_CODE
