Mappings to SNOMEDCT_US_2023_06_30
Term Type | Origin |
---|---|
FN | An "FN" atom is created for each line of
UMLS_MEDCIN_CONCEPTSyyyy-mm-dd.TXT, as follows: CODE = MEDCINID STR = CONCEPT_DESCRIPTION SCUI = MEDCIN ID |
PT | A "PT" atom is created for each line of
UMLS_MEDCIN_DESCRIPTIONSyyyy-mm-dd.TXT having PREF_FLAG_ID=1, as
follows: CODE = MEDCIN ID STR = DESCRIPTION SCUI = MEDCIN ID |
SY | An "SY" atom is created for each line of
UMLS_MEDCIN_DESCRIPTIONSyyyy-mm-dd.TXT having PREF_FLAG_ID=0, as
follows: CODE = MEDCIN ID STR = DESCRIPTION SCUI = MEDCIN ID |
XM | One"XM"(cross mapping set) atom is generated, as follows: CODE = "MTHU000001" STR = "MEDCIN3_yyyy_mm_dd to SNOMEDCT_US_yyyy_mm_dd Mappings" SCUI = "" (blank) This data is added during Metathesaurus source processing. |
Attribute Name | STYPE | Origin |

PREF_FLAG_ID | AUI | PREF_FLAG_ID from UMLS_MEDCIN_DESCRIPTIONSyyyy-mm-dd.TXT |

CHD PAR |
(blank) | Hierarchical relationships derived from the "NODEKEY" values in UMLS_MEDCIN_HIERARCHYyyyy-mm-dd.TXT. The final two-character token is removed from each concept's "NODEKEY" to produce the "NODEKEY" of the concept's parent. These two concepts are then linked by a pair of "PAR/CHD" relationships. |
RB RN RO SY |
(many RELA values) | Relationships are created for the MEDCIN-to-SNOMEDCT mappings in UMLS_MEDCIN_SNOMEDyyyy-mm-dd.TXT. The "REL" and "RELA" are set corresponding to the "RELATIONSHIPTYPE" field. |
One map set ("XM" atom, along with associated attributes and mappings) is included for MEDCIN. Mappings are extracted from the file "UMLS_MEDCIN_SNOMEDyy-mm-dd.TXT. Mappings are created for entries where the RELATIONSHIPTYPE = "168666000" (same_as).
