Data sovereignty & trust#

Part of the LDT Governance and Trust Framework — instantiates the iSHARE Data Space Template pillar Data Sovereignty & Trust (© iSHARE Foundation, see Legal notices).

Purpose#

Trust is the foundation of any data space: participants need to know who they are dealing with, and must be able to keep control over their own data. Three blocks provide the technical capability — identity & attestation management (who a participant is, and verifiable proof of their attributes or roles), trust framework (the shared baseline everyone follows), and access & usage policies enforcement (who may use data, under which conditions, enforced rather than merely promised).

LDT instantiation — where we stand#

This pillar is the core of the LDT and the part where the scheme is most nearly complete, because it is adopted rather than invented: the trust layer is the iSHARE (DataRights) Trust Framework 3.x, applied to the digital-twin domain, with iSHARE Foundation as Scheme Owner and sole party performing Trusted List and certification functions.

Two LDT-specific extensions carry real weight and are still open:

  • Commons controls — community-level control over citizen and community data, on top of standard access and usage policies. Standard participant-to-participant policy language does not express "the neighbourhood decides"; see Access & usage policies enforcement.
  • Non-EU credentials — Aruba Airport participates from outside the EU, so wallet and credential flows must hold up across that boundary; see Identity & attestation management.

The scheme's own rule: an operating condition that cannot be enforced by a credential check, an ODRL policy or a registry entry should be treated as a contract clause and named as such, not left as a technical aspiration.
