<p>Xiao: </p> <hr /> <div>{{Plugin<br /> |Description=Ontop is a platform to query databases as Virtual RDF Graphs using SPARQL. It's extremely fast and is packed with features. Ontop is an open-source Ontology Based Data Access (OBDA) system that allows for querying relational data sources through a conceptual representation of the domain of interest, provided in terms of an ontology, to which the data sources are mapped. Key features of Ontop are its solid theoretical foundations, a virtual approach to OBDA that avoids materializing triples and that is implemented through query rewriting techniques, extensive optimizations exploiting all elements of the OBDA architecture, its compliance to all relevant W3C recommendations (including SPARQL queries, R2RML mappings, and OWL 2 QL and RDFS ontologies), and its support for all major relational databases.<br /> |PluginType=Application<br /> |PluginType2=View<br /> |ForApplication1=Protege-OWL<br /> |HomepageURL=http://ontop.inf.unibz.it/<br /> |DeveloperID1=Mariano Rodríguez-Muro<br /> |DeveloperID2=Martin Rezk<br /> |DeveloperID3=Guohui Xiao<br /> |DeveloperID4=Diego Calvanese<br /> |LastUpdated=May 13, 2015<br /> |Topic1=Reasoning<br /> |Topic2=Import<br /> |Topic3=Inference<br /> |Topic4=Semantic Web<br /> |License=Apache 2<br /> |Affiliation1=Free University of Bozen-Bolzano, Italy<br /> }}</div>
