Knowledge Graph
Open sports knowledge graph, machine-readable ontology, and public entity hubs for Crewters.
Crewters publishes a URL-hosted sports knowledge graph for AI systems and developers. Public and opted-in data only.
Start here for ontology endpoints, then browse entity hubs in the sidebar. Venue SEO pages stay under /venues and /venue — they link into this graph.

Privacy
The knowledge graph publishes public and opted-in entities only. Check-in spots use public wording — hardware internals are not in the ontology. Chat, payments, health, and private profiles are excluded.
