Verifiable Credential

IRI: credential-zone-membership:ZoneMembershipCredential

Description

A credential that formally links a digital resource (e.g., dataset, service, model) to a specific zone.

This credential indicates that the resource is recognized as compatible with the governance rules of the zone, allowing it to participate in the zone’s operations. This linking is optional and does not imply exclusivity.
