I am looking for a single open source tool that allows editing of RDFS, RDF and full OWL 2.0 ontologies. Being able to execute SPARQL queries would be a very big bonus. Any recommendations ? Thanks |

Not exactly open source, but the Free Edition of TopBraid Composer meets the other requirements, including editing of RDF/RDFS or OWL 2 models, as well as SPARQL execution. |

Protege4 is open source and allows to create and edit RDF,RDFS and OWL2 Yeah, Protégé 4.1 definitely supports RDFS and OWL 2. It's java-ish. However, I'm afraid that Protégé 4.1 doesn't support SPARQL execution by native though you can use third-party SPARQL tools, such as Joseki and Jena. 2
Protege 4 does not fully support RDF/RDFS. It goes through the OWL API that turns everything into OWL. This will mess up things that OWL DL cannot handle (such as certain blank node structures). So yes to OWL 2, but no to RDF/RDFS and SPARQL. |
