OBO Format metamodel. This meta-ontology is self-describing. OBO metamodel properties are described using OBO metamodel properties
This is an OWL translation of an ontology whose native representational form isobo. The translation was performed using the oboInOwl xslt library. For details, see http://www.berkeleybop.org/obo-conv.cgi
database_cross_reference
definition
we are forced to use the n-ary relation pattern in OWL1.0. For OWL2 we may make this a direct axiom between a class and the string
The textual definition of the current term. There must be zero or one instances of this tag per term description
obsolete_class
pseudo-class. in the oboInOwl translation, all obsolete classes are subclasses of this class. Note that this is not a metaclass
subset
A grouping of terms from an ontology or ontologies. Note that this is not a metaclass - classes are linked to subsets via oboInOwl:inSubset
view
partition
slim
GO-slim
synonym
An instance of synonym usage. synonym instances are linked to classes via oboInOwl:has*Synonym properties
synonym_type
obsolete_property
pseudo-property. in the oboInOwl translation, all obsolete relations are subProperties of this class
consider
Gives a term which may be an appropriate substitute for an obsolete term, but needs to be looked at carefully by a human expert before the replacement is done
has_alternative_id
An alternative identifier for this class; should follow ID syntax. These can result from class merges
has_broad_synonym
An alias in which the alias is broader than the primary class name. Example: cell division is a broad synonym of cytokinesis
has_date
has_dbxref
has_default_namespace
has_definition
a relation between a class and an instance of a oboInOwl:Definition
has_exact_synonym
An alias in which the alias exhibits true synonymy. Example: ornithine cycle is an exact synonym of urea cycle
has_narrow_synonym
An alias in which the alias is narrower than the primary class name. Example: pyrimidine-dimer repair by photolyase is a narrow synonym of photoreactive repair
has_obo_namespace
A relation between a class and an OBO namespace string. OBO namespaces are to be distinguished from IDspaces; for example, biological_process is a namespace, GO is an idspace.
has_synonym
Note that this should be a super-property of hasRelatedSynonym, hasExactSynonym etc; however, we cannot state this and remain in OWL-DL
A relation between a class and an alias term.
has_related_synonym
An alias in which the alias is related the primary class name, but not necessarily broader or narrower. Example: cytochrome bc1 complex is a related synonym of ubiquinol-cytochrome-c reductase activity; virulence is a related synonym of pathogenesis
has_subset
relation between an ontology and a oboInOwl:Subset, indicating classes in the ontology belong to the subset
has_synonym_type
has_URI
has_version
in_subset
relation between a class and a oboInOwl:Subset, indicating the class belongs (is a member of) the subset
replaced_by
Gives a term which replaces an obsolete term. The value is the id of the replacement term. The value of this tag can safely be used to automatically reassign links to an obsolete term. The replaced_by tag may only be specified for obsolete terms. A single obsolete term may have more than one replaced_by tag. This tag can be used in conjunction with the consider tag.
saved_by
is_cyclic
subset_property
This annotation property groups all subsets declared in the ontology
synonym_type_property
This annotation property groups all synonym types declared in the ontology
