A semantic repository for heterogeneous ontologies

Ontohub is a repository engine for managing distributed heterogeneous ontologies. The distributed nature enables communities to share and exchange their contributions easily. The heterogeneous nature makes it possible to integrate ontologies written in various ontology languages. It supports a wide range of formal logical and ontology languages building on the OntoIOp.org project and allows for complex inter-theory (concept) mappings and relationships with formal semantics. Ontohub aims at satisfying a subset of the requirements for an Open Ontology Repository (OOR). OOR is a long-term international initiative, which has not resulted in a complete implementation so far, but established requirements and designed an architecture. Furthermore, Ontohub is being developed in close connection with the Distributed Ontology Language, which is going to be submitted as response to the Object Management Group’s Ontology, Model and Specification Integration and Interoperability (OntoIOp) Request For Proposal.
