We are happy to announce the availability of -ontop- v1.18 a Java framework to query ontologies with mappings to databases. If you are interested in virtual RDF graphs, R2RML mappings and/or RDFS/OWL2QL reasoning, then -ontop- is for you. The system implements the cutting edge SPARQL-to-SQL and query optimisation techniques that allow it to answer SPARQL queries using SQL databases while obtaining great performance. With -ontop-, you don't need to move your data from your already efficient database in order to enjoy the benefits of the RDF data model, the SPARQL query language or RDF/OWL2QL inference. And there is no need for expensive ETL or forward/backward chaining either. You can use -ontop- from command line, as a Java API, as a SPARQL end-point, or as a Protege plugin. After the deployment to -ontop- v1.17 to Protege plugin repository, we have received many feedback and bug reports, most of which are addressed in this new release. The highlights of this new release include: - Improvement of Protege plugin -- Redesigned materialization action dialog -- Upgrade to Protege 5.0.0 (latest version) -- Numerous bug fixes - Support of SPARQL querying of annotation property assertions in the ontology - Support of the use of owl:sameAs in mappings - Upgrade OWLAPI to v4.2.5 Further details in: https://github.com/ontop/ontop/wiki/OntopReleases#v1.18.0 The system is available for FREE at http://ontop.inf.unibz.it/ If you are a protege user, you will receive the new version of -ontop- plugin automatically. Please, try it out and help us improve it by sending us your feedback.
