Tool guide
Work with RDF Graph Viewer
On this page
The web edition inspects RDF metadata and namespaces, draws selected properties and offers SPARQL queries over the loaded file. It builds on the desktop edition by Christophe Roche.
Requirements
Use a current browser; no Python installation is required. The viewer supports ontoterminologies using RDF, RDFS, SKOS, OWL, OntoLex-Lemon and OTV.
Supported formats
RDF/XML (.rdf, .xml), Turtle (.ttl), JSON-LD (.jsonld) and N-Triples (.nt). TEDI and KGE RDF/XML exports can be used as input.
Workflow
- Upload the file and inspect its statistics and namespaces.
- Choose a small set of properties before generating the graph.
- Search and rearrange the network; query the uploaded file with SPARQL.
For the lab’s published datasets, use the separate TALOS SPARQL Endpoint.
Selecting properties
Relations between resources, literal values, and labels/comments offer different views of the same file. Start with otv:isA for the hierarchy; add otv:denotedByTerm to see the terms denoting concepts.
Troubleshooting
Failed upload: check serialisation and syntax. Slow rendering: select fewer properties. Missing metadata: check declared namespaces and owl:Ontology metadata in the source.
