AberOWL is an ontology repository and reasoning service developed by the Bio-Ontology Research Group (BORG) at KAUST. It loads biomedical ontologies into OWL reasoners (ELK by default) and offers Description Logic queries in Manchester OWL Syntax, full-text search over classes and ontologies, rewriting of SPARQL queries that embed OWL DL frames, a REST API and an MCP server for AI agents. Ontology metadata is synced daily from the OBO Foundry and BioPortal. As of 2026-10-04 it listed 971 ontologies with about 12.1 million classes, running on the redesigned Aber-OWL 2 software.

AberOWL is an ontology repository that provides reasoning as a service. It is developed by the Bio-Ontology Research Group (BORG) at King Abdullah University of Science and Technology (KAUST). Each ontology is loaded into an OWL reasoner (ELK by default, with Structural and HermiT available), so users can query it semantically and not just by label.
'part of' some 'cell'.Ontology metadata is synced daily from the OBO Foundry and BioPortal. The current deployment runs Aber-OWL 2, which splits the service into a central server and reasoner worker containers. When checked on 2026-10-04, the site listed 971 ontologies with about 12.1 million classes. Search and listing worked, but DL query endpoints reported that the reasoning backend was down.
