The TONES Ontology Repository is located in Manchester. To browse it, follow this link.


This repository is primarily designed to be a central location for ontologies that might be of use to tools developers for testing purposes.


The repository can be browsed here. The repository supports a RESTful interface. To access an ontology directly (e.g., to open an ontology from a tool such as Protege 4), the following syntax should be used:




Ontology file formats

The default file format that will be served is RDF/XML. However, the repository also stores ontologies in OWL/XML. To obtain an ontology as OWL/XML, the format=OWL/XML parameter should be added



The repository also stores ontologies without entity annotations. For certain ontologies (e.g the NCI Cancer ontology) this make a large difference to the size of the ontology. To request an ontology without annotations, specify a format of RDF/XML-WA.
