🔎 SPARQL Federation across FAIR Data Points

Run live SPARQL queries against RDF metadata from multiple registered FDPs. No server needed — Oxigraph runs a full SPARQL 1.1 engine entirely in your browser via WebAssembly, fetching Turtle files directly over HTTP.

Results will appear here after you run a query.

How this works

  1. Each registered FDP publishes one or more Turtle (.ttl) files served over HTTPS with open CORS headers — no dedicated SPARQL endpoint needed.
  2. Oxigraph is a W3C-standards-compliant SPARQL 1.1 engine compiled to WebAssembly. It runs entirely in your browser — no backend required. It fetches each source file, builds an in-memory RDF dataset, and evaluates your query.
  3. Results are rendered as an HTML table. URIs become clickable links; you can download results as CSV.
  4. You can freely edit the query in the editor above — it is plain SPARQL 1.1. Add FILTER, change variables, or adjust source selection.
  5. External FDPs (Duchenne, WikiPathways, SPHN) may block cross-origin requests depending on their CORS policy. The GA4GH BYOD sources always load — they are hosted on CORS-enabled static files.
  6. For Demo 2, submit a disease case via the BYOD form, wait ~60 s for the GitHub Action to run, then run the Community submissions query above to see it appear here.
