The TED Open Data Explorer lets you inspect the RDF data behind individual TED notices. Start from a publication number and navigate through the linked resources — lots, contracts, organisations, procedures — to understand how a notice is represented in the eProcurement Ontology (ePO).

For a broader introduction to TED Open Data, the eProcurement Ontology, and SPARQL, visit our documentation website.

How to use this tool

• Use the Search tab to look up a notice by its publication number (e.g. 00676595-2024).
• Click pick a random notice to explore a recent notice chosen at random.
• Results appear in the Explore tab as a collapsible tree of RDF triples.
• Use Tree view for a hierarchical, navigable structure.
• Use Turtle view to see the raw RDF serialization.
• Use Backlinks view to see which other resources reference the current one.
• Click the history button in the Search tab to revisit a past search; click Clear history at the bottom of that menu to wipe the list.

Navigating the tree

• Click any type badge to drill into that resource. Badge text reads "Type identifier" (e.g. "Lot LOT-0001", "SettledContract CON-0001") or just "Type" when the resource has no identifier.
• Your path is shown as a breadcrumb at the top of the Explore tab. Click any step to jump back.
• Each nested card shows a subject (e.g. a Lot, an Organization) with its properties.
• Click the icon in the breadcrumb to return to the notice you started with.

Procedure timeline

When you search a notice, its procedure timeline is shown in the Search tab and as a collapsible mini-card above the tree in the Explore tab. Every notice within the same procedure is listed with colour-coded cards: green for the original publication, yellow for subsequent amendments (marked with a v2, v3, … badge next to the publication number). Cards are ordered oldest-first; same-day amendments are broken by version. Click any notice in the timeline to navigate to it.

SPARQL mode

Switch the Search tab to SPARQL mode to run custom CONSTRUCT or DESCRIBE queries against the TED SPARQL endpoint. The query editor has syntax highlighting for SPARQL. For a library of example queries, see the TED Open Data Service.

Sharing

Click the share button to copy a URL that loads the current notice or query directly. Paste it into an email, a ticket, or another browser tab to share your exploration.
