| Term {SMRUCC.genomics.Data.GeneOntology.OBO} | .NET clr documentation |
The Structure of GO can be described In terms Of a graph, where Each GO term Is a node, And the relationships between the terms are edges between the nodes. GO Is loosely hierarchical, With 'child' terms being more specialized than their 'parent' terms, but unlike a strict hierarchy, a term may have more than one parent term (note that the parent/child model does not hold true for all types of relation) (功能定义,term相当于一个节点，节点之间的继承关系是非严格的，即某一个子节点可能会有多个父节点)
The following Is a GO term taken from the OBO format file.

# A textual description of what the term represents, plus reference(s) to the source of the information.
# All new terms added to the ontology must have a definition; there remains a very small set of terms
# from the original ontology that lack definitions, but the vast majority of terms are defined.

# One or more links that capture how the term relates to other terms in the ontology. All terms
# (other than the root terms representing each namespace, above) have an is a sub-class relationship
# to another term; for example, GO:0015758 : glucose transport is a GO:0015749 : monosaccharide transport.
# The Gene Ontology employs a number of other relations, including part of (e.g. GO:0031966 :
# mitochondrial membrane part of GO:0005740 : mitochondrial envelope) and regulates (e.g. GO:0006916 :
# anti-apoptosis regulates GO:0012501 : programmed cell death). The relations documentation has more
# information on the relations used in the ontology.
relationship: string;
replaced_by: string;
# Indicates that the term belongs to a designated subset of terms, e.g. one of the GO slims.
subset: string;
# Alternative words or phrases closely related in meaning to the term name, with indication of the relationship between the name
# and synonym given by the synonym scope. The scopes for GO synonyms are:
# + exact
# an exact equivalent; interchangeable With the term name
# e.g. ornithine cycle Is an exact synonym of urea cycle
# + broad
# the synonym Is broader than the term name
# e.g. cell division Is a broad synonym of cytokinesis
# + narrow
# the synonym Is narrower Or more precise than the term name
# e.g. pyrimidine-dimer repair by photolyase Is a narrow synonym of photoreactive repair
# + related
# the terms are related In some way Not covered above
# e.g. cytochrome bc1 complex Is a related synonym of ubiquinol-cytochrome-c reductase activity virulence Is a related synonym of pathogenesis
#
# Custom synonym types are also used In the ontology. For example, a number Of synonyms are designated As systematic synonyms;
# synonyms Of this type are exact synonyms Of the term name.
synonym: string;
# Database cross-references, or dbxrefs, refer to identical or very similar objects in other databases. For instance,
# the molecular function term retinal isomerase activity is cross-referenced with the Enzyme Commission
# entry EC:5.2.1.3; the biological process term sulfate assimilation has the cross-reference MetaCyc:PWY-781.
