IBM Web Ontology Manager ... What is IBM Web Ontology Manager? IBM Web Ontology Manager is a lightweight, Web-based tool for managing ontologies expressed in Web Ontology Language (OWL). With this technology, users can browse, search, and submit ontologies to an ontology repository. Developers can discover new ontologies without having to develop the ontology themselves; reusability is thereby promoted and development time and effort is reduced. This technology includes a Web interface for easy uploading of ontologies in an .owl format by any user of the system. It also includes an interface for generating (using Jastor) Java≥ APIs from uploaded ontology files. IBM Web Ontology Manager differs from IBM Ontology Management System (a former alphaWorks technology, now merged into the IBM Integrated Ontology Development Toolkit) in that it does not include a statement repository. Instead, based on the ontologies visible to the system, it can generate Java classes for accessing any Jena-compatible RDF statement repository. How does it work? Ontology developers can browse or search the ontologies registered with the system by class or property names. In addition, they can submit a new ontology file. The system is designed to promote reuse, so submitters will be presented with a similarity report containing information on duplication or similarity between the classes contained in their ontologies and the classes known to the system. The ultimate decision of whether to accept or reject the submission lies with the system administrator. The system generates Jastor-binding Java classes for all ontologies present in the system and makes them available for download. The developer then uses the generated Jastor classes to interact directly with the data repository.
