  and https://dataeuropa.gitlab.io/data-provider-manual/api-documentation/api-store/
summary:

  - header
  public_read: true
  note: 'Reads are anonymous across every API — search, MQA metrics, MQA reporter, SHACL validation, statistics and SPARQL
    all answer without a credential (verified live). Credentials are only needed to WRITE into a catalogue, and they
    are not self-service: access is granted by the portal team to a catalogue you are responsible for.'

flows:
- name: Service account (client credentials via the access-control middleware)
  steps:
  - POST https://data.europa.eu/auth/middleware/login/service with JSON {client_id, client_secret}
  - 'Response: {"access_token": "..."}'
  - 'Send the token as Authorization: Bearer <token> to hub-repo and hub-store'
  audience: hub-repo, hub-store
  source: https://dataeuropa.gitlab.io/data-provider-manual/api-documentation/api-access-control/
- name: EU Login user + UMA 2.0 party token (Keycloak realm DEU)
  steps:
  - POST https://data.europa.eu/auth/realms/DEU/protocol/openid-connect/token with grant_type=password, client_id=piveau-hub-ui,
    username, password — returns a user token (expires_in 300, refresh_expires_in 1800, scope 'email profile')
  - 'POST the same token endpoint with grant_type=urn:ietf:params:oauth:grant-type:uma-ticket and audience=piveau-hub-repo,
    carrying the user token as Authorization: Bearer — returns the party token'
  - Use the party token to manage datasets in data.europa.eu
  audience: piveau-hub-repo
  token_ttl_seconds: 300
  refresh_ttl_seconds: 1800
  source: https://dataeuropa.gitlab.io/data-provider-manual/api-documentation/api-access-control/
- name: Catalogue-scoped API key
  steps:
  - Send the key in the X-API-Key header
  note: Declared as ApiKeyAuth in all three write-bearing contracts; issuance is handled by the portal team, not documented
    as self-service.
  source: openapi/eu-open-data-portal-hub-repo-openapi.yaml
identity_provider:
  type: keycloak
  realm: DEU
  token_endpoint: https://data.europa.eu/auth/realms/DEU/protocol/openid-connect/token
  middleware_endpoint: https://data.europa.eu/auth/middleware/login/service
  discovery_document: https://data.europa.eu/auth/realms/DEU/.well-known/openid-configuration
  discovery_status: 403
  discovery_note: The realm is real and documented, but its OIDC discovery document is blocked at the edge (HTTP 403
    probed 2026-09-07), so a client cannot auto-configure.
access_control:
  model: catalogue-scoped, plus ODRL policy-based access control on datasets
  note: hub-search 5.3.7 added policy-based access control evaluating ODRL constraints on datasets against JWT claims,
    and 5.3.9 made multiple ODRL policies combine as AND restrictions (service changelog).
  source: https://gitlab.com/dataeuropa/hub/search/-/blob/master/CHANGELOG.md
gaps:
- No scopes are documented anywhere — the observed OIDC scope string is the default "email profile", and no scopes/ artifact
  is emitted because there is no scope surface to record.
- Unauthorized and Forbidden are declared as null entries in hub-search components.responses while 401/403 are referenced
  by operations.
