We have a number of OWL-related service available over the web. These have been implemented using the WonderWeb OWL API.

• OWL Species Validator. This will check OWL-RDF documents for basic syntactic errors and will determine whether a document belongs to a particular sub-species of the language. The Validator can also provide an Abstract Syntax Presentation of an OWL ontology.
• OWL Presentation Service. Provides a basic HTML rendering of an OWL ontology.
• OWL Patcher Service. Takes an ontology in RDF form and tries to work out what changes (if any) are necessary to produce an OWL DL ontology. For example, missing type triples may need to be added.
