— Virtuoso-powered SPARQL endpoints

A filterable knowledge-graph view of the Virtuoso segment in the LOD Cloud endpoint analysis.

Snapshot: source sheet read and endpoint availability checked 16 September 2026. Only operational, unique SPARQL endpoint URLs are included; all Bio2RDF nodes are excluded. Triple counts are shown exactly as recorded. Open source sheet ↗

Virtuoso endpoint graph

Directed links use ssn:deployedOnPlatform.

Knowledge graph of Virtuoso-powered SPARQL endpoints Endpoint nodes connect to their recorded Virtuoso edition with ssn:deployedOnPlatform. Node radius uses a logarithmic scale when a triple count is present.

How to read the graph

Every directed edge is ssn:deployedOnPlatform. Edge labels are links to the W3C SSN predicate through the configured resolver; hover an edge to read its semantic description.

Radius is logarithmic. It preserves the enormous range—from tens of thousands to tens of billions of triples. Hollow endpoint nodes have no triple count in the source.

Open Controls to search, filter, switch Core/Full density, or enter Advanced mode. Drag a node to pin it, double-click to unpin it, and click the graph before panning or zooming.

Visible records

Filtered where “dbms or store” is OpenLink Virtuoso, then limited to endpoints verified operational on 16 September 2026. Bio2RDF nodes are excluded. Counts, editions, versions, names, and endpoint URLs come from the linked source sheet.
