## What it is

- Vendor-neutral meeting place for the open health data community, founded by Jan de Lange
  and Bouwe Koopal. "Yellow" for the Yellow Pages (who builds what); "Brink" is Dutch for
  the village square where people gather.
- Activities: weekly webinars run in cooperation with openEHR NL, country groups (e.g.
  "openEHR in the Netherlands"), special interest groups, discussion and co-creation rooms,
  and "The Brink" partner/meeting area at the EHRCON26 conference.
- Education: developing a postdoctoral European Master of Data Availability (MDA) programme
  with European universities and hospital systems.

## API surface

- No public API. No developer portal, no OpenAPI/AsyncAPI/GraphQL contract, no SDK, no
  webhook catalog, no MCP server, no A2A agent card.
- The web application at https://www.yellowbrink.com/ is a white-labelled tenant of the
  Innoloft LoftOS platform (assets served from app-cdn.innoloft.com, fonts.loftos.io). Its
  backing API is https://api.innoloft.com, which belongs to Innoloft, NOT to YellowBrink,
  and returns HTTP 401 to anonymous requests. Nothing from that host is attributed here.
- Every path on www.yellowbrink.com — including /openapi.json, /swagger.json, /llms.txt and
  every /.well-known/* path — returns the same 12,016-byte client-side HTML shell.
