Each relation in RO is uniquely identifier by a URI of the form http://purl.obolibrary.org/obo/RO_nnnnnnn

Examples:

Each of these URIs has a corresponding OBO-identifier short form RO:nnnnnnn

Note that in OBO-format, use of a shorthand is permitted. For example, in:

[Term]
id: GO:2001284
name: regulation of BMP secretion
intersection_of: GO:0065007 ! biological regulation
intersection_of: regulates GO:0038055 ! BMP secretion

...

[Typedef]
id: regulates
name: regulates
transitive_over: part_of ! part_of
xref: RO:0002211

The equivalence axiom is translated to OWL as:

EquivalentClasses(GO_2001284 ObjectIntersectionOf(GO_0065007 ObjectSomeValuesFrom(RO_0002211 GO_0038055)))

see Section 8.2.2 of the obo-format specification for details
