A nonprofit initiative with leading open-source partners

From a web of URLs to an open source graph of entities.

OpenData.org is the world's largest open directory of entities: 324 million organizations, 1.2 billion people, and 512 million places, linked by the identifiers every field already uses. The Rosetta Stone that grounds compliance, AI, and science in verified facts.

The Rosetta Stone of entity identifiers.

/ CONNECTED

162 reference identifiers linked so anything joins to anything on a stable, verified key.

/ NONPROFIT + NEUTRAL

A nonprofit initiative partnered with leading open-source organizations, including the Linux Foundation. Open governance: no single vendor controls it.

02 — Why now

AI agents need to know which entity is which.
