LANGUAGECODE	SNOMED CT string identifying a language and, if appropriate, a dialect in which this description is valid.	1144323
CONCEPTSTATUS	SNOMED CT status which indicates whether a concept is in active use and, if not, indicates the reason it is inactive.	386965

SNOMEDID	SNOMED RT identifier for a SNOMED CT concept	386965
AQ	SNOMED CT "allowable qualifier" attribute for representing certain relationships (those having a characteristic type of "Qualifier" and a refinability of "Mandatory") which indicate one of several allowable types of qualifiers, such as laterality or severity, that a concept may have	301505
UMLSREL	The UMLS Metathesaurus REL relationship (SY, CHD, NT, BT, RT) assigned to SNOMED CT relationship identifiers.	65

SUBSETCONTEXTID	SNOMED CT identifier of a subset	2
SUBSETLANGUAGECODE	SNOMED CT identifier of a language and, if appropriate, a dialect to which a subset applies.	2
SUBSETORIGINALID	SNOMED CT identifier for the first version of the subset on which this subset is based.	2
SUBSETREALMID	"Realm" or context in which a SNOMED CT subset is used, e.g., nation, speciality, institution, etc. to which it applies. A four-character ISO6523 identifier followed by an optional series of concatenated subdivisions codes defined by the registered organization.	2
SUBSETTYPE	Single digit integer indicating the nature of a SNOMED CT subset and the type of SNOMED CT component that may be a member of the subset. The meaning of the non-zero values can be found in the SNOMED CT documentation; a value of 0 is not defined as a type.	2

MAPSETNAME	Official name of a map set	1
MAPSETREALMID	Identifier of a "Realm" to which a source is mapped, within which this cross mapping table is applicable. Used in cases where Realm specific business rules or guidelines alter the acceptable mappings. Realm is the same as used in SNOMED CT subsets. It includes a four character ISO6523 identifier followed by an optional series of concatenated subdivision codes defined by the registered organization.	1
MAPSETRSAB	Root source abbreviation for a map set	1
MAPSETRULETYPE	Indicates the types of rules used in a map set and cross map targets to which a source is mapped.	1
MAPSETSCHEMEID	Standard identifier for the scheme to which a map set belongs. This may be an International Coding Scheme Identifier (ISO7826) or an Object Identifier (OID) used as specified by HL7.	1
MAPSETSCHEMENAME	Full name of the target scheme in a map set.	1
MAPSETSCHEMEVERSION	Version number of the target scheme (as published by the issuing organization) in a map set.	1
MAPSETSEPARATORCODE	XML entity code (for example, "&#7c;" to represent the vertical-bar character) for the character used as a separator between the individual codes in the target codes field in a map set.	1
MAPSETSID	Source asserted identifier for a map set	1
MAPSETTYPE	Indicates the nature of a map set. Its value is map set specific. It can be used to indicate the inclusion of one to one, one to many and choices of maps.	1
MAPSETVERSION	Version of the map set	1
MAPSETVSAB	Versioned source abbreviation for a map set	1
MAPSETXRTARGETID	Map set target identifier used for XR mappings.	1
MTH_MAPFROMCOMPLEXITY	Indicates the complexity of "from" expressions used in a map set	1
MTH_MAPFROMEXHAUSTIVE	Indicates whether or not the "from" source of a map set is completely mapped	1
MTH_MAPSETCOMPLEXITY	Indicates the overall complexity of a map set	1
MTH_MAPTOCOMPLEXITY	Indicates the complexity of "to" expressions in a map set	1
MTH_MAPTOEXHAUSTIVE	Indicates whether or not the "to" source is completely mapped	1
MTH_UMLSMAPSETSEPARATOR	The character used in the UMLS Metathesaurus as a separator between the individual codes in the target codes field of the cross map targets to which a source is mapped.	1
SOS	Scope Statement	1
TARGETSCHEMEID	Identifier for the target scheme in the map set. This may be an International Coding Scheme Identifier (ISO7826) or an Object Identifier (OID) used as specified by HL7.	1

TOVSAB	Versioned source abbreviation for the "to" identifiers of a map set	1

Notes

• Attributes included every discrete piece of information about a concept, an atom, or a relationship that is not part of the basic Metathesaurus concept structure or distributed in one of the relationship files.
• Attribute Names (ATN) are based on source documentation or NLMs understanding of the source.
• Sample attribute values (ATV) are provided for each ATN in the source.
• Sample data highlight examples of ATNs and Attribute Values (ATV) in MRSAT.RRF.
• See Appendix B.2 for a complete list of attribute names.
• See UMLS Documentation Section 2.7.1.3.5 for more information on MRSAT.RRF.
