The COBrA-CT project has developed tools for editing OBO ontologies, and for
managing ontologies in the Web Ontology Language, OWL.
Bio-ontologies formalise our knowledge of molecular function, biological process, anatomy
and cell type across the phyla. As with databases, bio-ontologies are created, published and
updated over time. Ontology curation is typically a joint effort between subject matter experts,
database curators and experimentalists. Hence tools for ontology curation should support
sharing ontologies, managing versions, annotating changes to them, and visualising those
changes over time.
The OBO Explorer Ontology Editor
OBO Explorer ontology editor is compatible with the proposed standard
for transitioning Open Biomedical Ontologies (OBO) to OWL. The
OBO-In-OWL format includes an agreed representation for synonyms,
subsets and database cross-references as well as an interpretation of
OBO relationships as Description Logic property restrictions. These
