Data Sovereignty in Practice

Data sovereignty is the principal adoption barrier in digital agriculture. AgriFoodData treats it as a technical problem — not a contractual one.

Three guarantees​

  1. Fine-grained, technically enforceable access control. Farmers grant access at the level of a field, a region, or a datastream — not the whole farm.
  2. Audit log. Every grant, revocation, read and write is recorded. The farmer can inspect the log at any time.
  3. Revocability. Access can be withdrawn at any time. Once revoked, a service can no longer read the data or produce new outputs against it.

Mechanism — the clearing house​

The clearing-house ties usage policies to data exchange:

  • Usage policies are expressed in IDSA terms — what may a service do with the data, for how long, for which purpose.
  • Contracts are issued when a farmer grants access; they reference both the data resource and the policy.
  • Enforcement happens at the integration boundaries — the data connector refuses to deliver data to a service that does not present a valid contract.

Data spaces​

AgriFoodData participates in GAIA-X and IDSA-aligned data spaces, so data exchange outside a single deployment uses existing data-space contracts rather than ad-hoc data dumps.
