Last 90 days
No data yet.
What we check
- The endpoint answers and its ontology metadata graph lists every ontology, through public DNS and on each node.
- The triple store and the REST API agree on the number of ontologies.
- The bare host redirects to the HTTPS SPARQL page on the same name, not to an internal port.
- Browser clients on other sites may query the endpoint (CORS allows any origin).
- The endpoint publishes a SPARQL service description; amber while it names an internal address instead of the public one.
- The SPARQL name resolves to tgx1 through two public resolvers, and they agree.
