Agrovoc alignment to OBO Ontologies

This is an exploratory project to align Agrovoc to OBO Library ontologies, in order to

• identify gaps in ontologies such as ENVO and TO
• Provide definitions (with full provenance) for OBO classes
• Provide language translations for OBO classes
• To explore the addition of OWL semantics to Agrovoc, beyond what can be done in SKOS
• To explore the possibility of closer integration and collaboration between Agrovoc and OBO communities

For more on OBO, see http://obofoundry.org

OWL translation of Agrovoc

The prolog program skos2obo.pl translates the skos of agrovoc to OBO/OWL

Note that for compactness we store the OWL in the compact OBO-Format, but this should be understood to have OWL semantics.

We also provide subset files for convenience. E.g. for aligning to NCBITaxonomy we would use subset-organisms.obo

MIREOTing Agrovoc into OBO Library ontologies

If we can get permission to publish the obo/owl via a purl we can MIREOT in Agrovoc classes to OBO Library ontologies (would also need CC-BY).

We would want to swap out some agrovoc PURLs with existing OBO purls - the above mappings can help with this. For example, we would always use an NCBITaxon purl for a taxon, or a PO purl for a plant part, a CHEBI purl for a chemical, etc.

However, with MIREOTing we will run into issues of differing semantics:
