Identifiers:

Identifiers are assigned as follows:
Identifier Origin
CODE tag = "id"
SAUI Not Applicable
SCUI Not Applicable
SDUI tag = "id"

Atoms (MRCONSO):

Term Type Origin
ET CODE: tag = "id"
STR: tag = "synonym"
SDUI: tag = "id"
TTY = "ET" is assigned to the value of tag = "synonym" where the scope identifier is "BROAD," "NARROW," or "RELATED" in records where there is no "is_obsolete" tag.
IS CODE: tag = "id"
STR: tag = "synonym"
SDUI: tag = "id"
TTY = "IS" is assigned to the value of tag = "synonym" where the scope identifier = "EXACT" and tag="is_obsolete" has a value of "true."
MTH_ET CODE: tag = "id"
STR: tag = "synonym," with the word "location" included for clarification of selected strings from the Cellular Component Ontology.
SDUI: tag = "id"
TTY = "ET" is assigned to the value of tag = "synonym" where the scope identifier is "BROAD," "NARROW," or "RELATED" in records where there is no "is_obsolete" tag. For the GO Cellular Component Ontology, additional atoms are created for selected strings by including the word "location" in the STR, and prepending the TTY with "MTH_." This data is added during Metathesaurus source processing.
MTH_IS CODE: tag = "id"
STR: tag = "synonym" with the word "location" included for clarification of selected strings from the Cellular Component Ontology.
SDUI: tag = "id"
TTY = "IS" is assigned to the value of tag = "synonym" where the scope identifier = "EXACT" and tag="is_obsolete" has a value of "true." For the GO Cellular Component Ontology, additional atoms are created for selected strings by including the word "location" in the STR, and prepending the TTY with "MTH_." This data is added during Metathesaurus source processing
MTH_OP CODE: tag = "id"
STR: tag = "name" with the word "location" included for clarification of selected strings from the Cellular Component Ontology.
SDUI: tag = "id"
TTY = "OP" is assigned to the value of tag = "name" where tag = "is_obsolete" has a value of "true." For the GO Cellular Component Ontology, additional atoms are created for selected strings by including the word "location" in the STR, and prepending the TTY with "MTH_." This data is added during Metathesaurus source processing
MTH_PT CODE: tag = "id"
STR: tag = "name" with the word "location" included for clarification of selected strings from the Cellular Component Ontology.
SDUI: tag = "id"
TTY = "PT" is assigned to the value of tag = "name" in records where there is no "is_obsolete" tag. For the GO Cellular Component Ontology, additional atoms are created for selected strings by including the word "location" in the STR, and prepending the TTY with "MTH_." This data is added during Metathesaurus source processing
MTH_OET CODE: tag = "id"
STR: tag = "synonym," with the word "location" included for clarification of selected strings from the Cellular Component Ontology
SDUI: tag = "id"
TTY = "OET" is assigned to the value of tag = "synonym" where the scope identifier is "BROAD," "NARROW," or "RELATED" in records where is_obsolete has a value of "true." For the GO Cellular Component Ontology, additional atoms are created for selected strings by including the word "location" in the STR, and prepending the TTY with "MTH_." This data is added during Metathesaurus source processing.
MTH_SY CODE: tag = "id"
STR: tag = "synonym" with the word "location" included for clarification of selected strings from the Cellular Component Ontology.
SDUI: tag = "id"
TTY = "SY" is assigned to the value of tag = "synonym" where the scope identifier is "EXACT" in records where ethere is no "is_obsolete" tag. For the GO Cellular Component Ontology, additional atoms are created for selected strings by including the word "location" in the STR, and prepending the TTY with "MTH_." This data is added during Metathesaurus source processing
OET CODE: tag = "id"
STR: tag = "synonym"
SDUI: tag = "id"
TTY = "OET" is assigned to the value of tag = "synonym" where the scope identifier is "BROAD," "NARROW," or "RELATED" in records where is_obsolete has a value of "true."
OP CODE: tag = "id"

SDUI: tag = "id"
TTY = "OP" is assigned to the value of tag = "name" in records where is_obsolete has a value of "true."
PT CODE: tag = "id"
STR: tag = "synonym"
SDUI: tag = "id"
TTY = "PT" is assigned to the value of tag = "name" in reocrds with no "is_obsolete" tag.
SY CODE: tag = "id"
STR: tag = "synonym"

Attributes (MRSAT):

Attribute Name Origin
DATE_CREATED tag = "creation_date"
DISJOINT_FROM tag = "disjoint_from"
GO_COMMENT tag = "comment"
GO_NAMESPACE tag = "namespace"

GXR tag = "xref""
REF tag = "synonym," dbxref list (information extracted from square brackets at the end of the field)
SID tag = "alt_id"
SYN_QUALIFIER tag = "synonym," qualifier (information following the scope identifier; currently the only value is "systematic synonym")

RO regulates
regulated_by
tag = "relationship"; value = "regulates"
RQ consider
