Base registries are the cornerstone of European public service delivery. A base registry is a trusted and authoritative source of information, which can and should be digitally reused by others, where one organisation is responsible and accountable for the collection, use, updating and preservation of information.

A base registry framework, ‘describes the agreements and infrastructure for operating base registries and the relationships with other entities’.
