2. BASE REGISTRIES
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.
Base registries are reliable sources of basic
information on data items such as people, companies,
vehicles, licences, buildings, locations and roads.
This type of information constitutes the ‘master data’
for public administrations and European
public service delivery.
