Biorelations
The GBIF terms biorelation vocabulary is a vocabulary to express relations between biological objects, parts and structures, habitats, molecules, etc. In its first iteration, it is closely modeled after a subset of the OBO Relation ontology (RO, http://code.google.com/p/obo-relations/) which replace the earlier OBO_REL ontology (http://www.obofoundry.org/ro/). The reasons for providing a separate ontology are to provide the ability to extent with additional terms and make the dependency on the owl productions of RO optional.
Namespace URI: http://rs.tdwg.org/biorel/ with preferred namespace prefix “biorel”.The namespace URI http://terms.gbif.org/biorel/1.0/ that is based on the SMW-import-page MediaWiki:Smw import biorel (used, e.g. for RDF export) differs from the namespace URI definitions on Biorelations (http://rs.tdwg.org/biorel/)—please correct one of these.
