Agents, roles and no personal data in the graph
Status: proposed
People and organisations appear in the graph only as agent IRIs and the roles they hold. Names, identity numbers, contacts, addresses, bank details, signatures and photographs of people stay in the project’s people register or evidence store. Records reference them by content address and never carry their values. Fields that capture personal data are marked as personal fields in the instrument mapping.
The people register is operational, not a secret from the project’s own staff. Field teams use it to reach participants, owners and managers, by telephone if need be, and the operational layer joins contacts to work at the time they are viewed (novaOS ADR-0006). Who may read which personal fields is the project’s access policy, and every read is logged. Nothing from it is published or enters the ledger.
Collector is a role. Its kind (informal waste picker, cooperative member, municipal crew, contractor) comes from a scheme. Field roles (enumerator, recruiter, placement agent, evaluator, supervisor) and facility operator are observer roles, and the observer’s role grades the evidence. An evaluator never evaluates service points on a round they collected. Participants take part for a service point as occupant, owner or responsible party.
A collector’s GPS trail is evidence that a round happened. Because it tracks an identifiable person, it stays in the evidence store. The graph holds service outcomes, not trails.
