This gives instructions on how to use RO in conjunction with ontologies whose source is obo-format.
See http://oboformat.org for more information on OBO-Format and its relationship to OWL.
Merge vs Import
Imports is not well-supported in Obo Edit, so the best strategy is to copy in the portion of the stanza you require from ro.obo
Note that you can use a shortcut ID for the relation within the file.
For example, GO has:
[Typedef] id: occurs_in name: occurs in xref: BFO:0000066 transitive_over: part_of ! part_of
This means that this stanza portion:
[Term] id: GO:0090144 name: mitochondrial nucleoid organization ... intersection_of: GO:0090143 ! nucleoid organization intersection_of: occurs_in GO:0005739 ! mitochondrion
is translated to:
Class: obo:GO_0090144 EquivalentTo: GO_0090143 and BFO_0000066 some GO_0005739
The same holds by default for RO IDs.
Other URI schemes are possible using the idspace tag
