SPARQL query

Thanks to the YASGUI editor of Triply, it is possible to ask Leonardi.DB any query using SPARQL syntax. To be able to construct meaningful queries, take a look at the overview of Leonardi, a visualization of the ontology, or the hierarchies of Aristotelian families and geometric shapes underlying the database. Prefixes for the namespaces used in Leonardi are already entered in each tab of the editor (collapsed to a single line).
