SPARQL panel ​

The button in the header opens a read-only SPARQL panel, a syntax-highlighting editor for running your own queries against the current endpoint.

The SPARQL panel with named query tabs, a highlighted SELECT over CORDIS organisations using property paths, and a paginated results table of URIs, acronyms, countries, and VAT numbers
  • Read-only. The four SPARQL read forms run — SELECT, ASK, CONSTRUCT and DESCRIBE. Any write/update verb (INSERT, DELETE, LOAD, CLEAR, DROP, …) is refused before any request is sent.
  • Many named tabs. Keep several queries side by side: + opens a new tab, double-click a tab to rename it, ✕ closes it. Tabs (and their queries) are remembered per endpoint across reloads and endpoint switches.
  • Graph queries as triples. CONSTRUCT and DESCRIBE return an RDF graph, shown as a subject / predicate / object table with the same clickable URIs as any other result. (A bare DESCRIBE <uri> runs as-is; otherwise graph queries get the same automatic LIMIT as a SELECT.)
  • Automatic LIMIT. A SELECT/CONSTRUCT/DESCRIBE with no top-level LIMIT gets LIMIT 1000 appended, and the panel tells you when it did. Turn this off with the Auto-limit toggle (or in Settings) to run the full result set. At most 1,000 rows render regardless.
  • Paginated results. The results table pages (50 per page) so a large result stays navigable.
  • Portable queries. Full IRIs are written as prefix:local with a PREFIX prologue, and any prefix you type is auto-declared on Run — so the query in the editor is a complete, standalone query you can copy into any SPARQL tool. (Prefixes come from the shared prefix map, scoped to what the endpoint uses.)
  • Run it. Press Run, or ⌘/Ctrl+Enter. The query duration is shown on success.
  • Clickable results. In a SELECT or CONSTRUCT/DESCRIBE table, URI cells are links — click one to open that resource in the browser. ASK shows a simple true / false.

Open in SPARQL ​

You don't have to write the query yourself. Above every instance list, a SPARQL button hands the current list — with its type, graph scope, text filter, and every active facet applied — to the panel as the exact query behind it, opened in a fresh tab. Use it to see how the filtered view is built, then refine it by hand.

Because the handed-off query is portable (qnames + PREFIX header, dotted triples), you can copy it straight out into another SPARQL client.
