Use the data. Keep the evidence attached.

Download release 0.8

The public release endpoint is the machine-readable snapshot behind the map and registry. It includes the release manifest, stable Station and Link views, the complete normalized Claim and Source graph, explicit claim-to-source edges, unresolved review records, and license metadata.

This endpoint now carries the reusable claim graph. Keep record identifiers, assertion and review states, caveats, claim-source edges, and attribution attached when transforming it.

What you may do

You may copy, redistribute, analyze, transform, and build upon OGS Tracker’s compiled release data for any purpose, including commercial use, under the Creative Commons Attribution 4.0 International license ↗.

The licensed material includes the OGS Tracker release datasets, stable identifiers, schema selections, normalized relationships, and original editorial annotations where OGS Tracker holds the relevant rights.

What attribution requires

Credit OGS Tracker, identify the release or access date, link to this page or the source dataset, link to CC BY 4.0, and say whether you changed the material. Do not imply that OGS Tracker or any listed organization endorses your product or interpretation.

Cite the underlying sources

CC BY 4.0 applies to the OGS Tracker compilation and original material—not automatically to papers, operator documents, government publications, photographs, logos, trademarks, or other linked source content. Each source retains its own copyright, license, and terms.

When you publish or rely on a specific fact, keep its claim-to-source citation and cite the primary source as well as OGS Tracker. A record citation is a trail to the evidence, not a transfer of rights in the evidence.

Map and image attribution

No operational warranty

The data is provided as-is and may be incomplete, stale, inferred, disputed, or wrong. Compatibility assessments describe what might work under stated inputs; they are not proof of a demonstrated link, a booking commitment, an engineering certification, or legal advice. Verify critical decisions with the operator and the cited source.
