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 |
