go.obo | OBO data file |
Not included:
* Certain fields and data elements may not be directly
processed because they contain redundant data.
In OBO, content is structured as tag-value pairs, with optional trailing modifiers. Tag-value pairs consist of a tag name, an unescaped colon, the tag value, and a newline.
Consult the GO OBO format documentation for additional details.
Tag Name | Description | Representation |
---|---|---|
id | Unique identifier | MRCONSO.CODE, MRCONSO.SDUI |
name | Term name | MRCONSO.STR
TTY = "PT" if there is no is_obsolete flag TTY = "OP" if is_obsolete = true |
namespace | Ontology (domain) name. Valid values are: biological_process
cellular_component molecular_function |
MRSAT.ATN = "GO_NAMESPACE" |
Tag Name | Description | Representation | ||||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
alt_id | Alternate identifier | MRSAT.ATN = "SID" | ||||||||||||||||||||||||||||||||||||
def | Definition | MRDEF.DEF | ||||||||||||||||||||||||||||||||||||
comment | Comment | MRSAT.ATN = "GO_COMMENT" | ||||||||||||||||||||||||||||||||||||
subset | Subset. Valid values are: goslim_candida
goslim_generic goslim_goa goslim_pir goslim_plant goslim_pombe goslim_yeast gosubset_prok |
MRSAT.ATN = "GO_SUBSET" | ||||||||||||||||||||||||||||||||||||
synonym | Synonym | MRCONSO.STR TTYs are assigned based on the value of the scope identifier and the presence or absence of the "is_obsolete" tag. MRREL.REL REL values are assigned based on the value of the scope identifier
Optional dbxref lists included in synonym tags are represented in MRSAT.ATN = "REF" When present on "EXACT" synonyms, the modifier "systematic_synonym" is represented in MRSAT.ATN ="SYN_QUALIFIER," MRSAT.ATV="systematic_synonym" |
||||||||||||||||||||||||||||||||||||
xref | Cross-reference (dbxref) describing an analagous term in another vocabulary | MRSAT.ATN = "GXR" | ||||||||||||||||||||||||||||||||||||
is_a | Indicates a subclassing relationship between one term and another | Used to create a hierarchy, represented in MRHIER.RRF and MRREL.RRF (REL = "PAR," "CHD"; RELA = "isa") | ||||||||||||||||||||||||||||||||||||
relationship | Describes a relationship between one term and another.
Valid values are: ends_during
happens_during has_part negatively_regulates occurs_in part_of positively_regulates regulates |
MRREL.RELA For part_of, MRREL.REL = "RN/RB" For all other relationship tag values, MRREL.REL = "RO" |
||||||||||||||||||||||||||||||||||||
is_obsolete | Indicates if a term is obsolete | Used to compute termtype assignments | ||||||||||||||||||||||||||||||||||||
replaced_by | Gives a term which replaces an obsolete term | MRREL.REL = "RO" MRREL.RELA = "replaced_by/replaces" |
||||||||||||||||||||||||||||||||||||
consider | Gives a term which may be an appropriate substitute or an obsolete term, but requires human review | MRREL.REL = "RO" MRREL.RELA = "consider/consider_from" |
||||||||||||||||||||||||||||||||||||
disjoint_from | Indicates that a term is disjoint from another, meaning that the two terms have no instances or subclasses in common. The value is the id of the term from which the current term is disjoint. | MRSAT.ATN = "DISJOINT_FROM" | ||||||||||||||||||||||||||||||||||||
intersection_of | Indicates that this term is equivalent to the intersection of several other terms. The value is either a term id, or a relationship type id, a space, and a term id. | If the value is a GO term id: MRREL.REL = "RN/RB";
MRREL.RELA = "isa/inverse_isa" If the value includes a relationship type: MRREL.REL and MRREL.RELA are populated appropriately based on the value of the relationship type. Relationship groups are used tolink pairs (or groups) of intersecting relationship. |
||||||||||||||||||||||||||||||||||||
creation_date | Indicates the creation time and date of the term | MRSAT.ATN = "DATE_CREATED" |
