Base registers and system standards Archives

The system of base registers consist of 10 separate fundamental, interconnected registers. To realise this connectivity, system standards have been agreed upon. For instance, because data from one base register are also used in another one. To ensure an effectively operating, interconnected system, standards have been agreed upon.

Administrative facility BSN

The administrative facility citizen service number (in Dutch: Beheervoorziening burgerservicenummer, BV BSN) is in charge of generating, issuing, managing, and consulting the citizen service number (BSN). The BV BSN controls access to the identifying data in the underlying authentic registers (Municipal Key register Personal Data, or GBA in Dutch, and the Non-residents Records Database). It also controls access to the verification registers for identity documents, to verify identity at the counter.

BAG

The Key register Addresses and Buildings (in Dutch: Basisregistratie Adressen en Gebouwen, BAG) contains municipal basic data of all addresses and buildings inside the municipality. Copies of these data are collected in a National Facility (Landelijke Voorziening, BAG LV). The Dutch land registration organisation Kadaster manages the BAG LV, and provides data to public offices, institutions, companies, and private citizens. The Minister of the Interior and Kingdom Relations is responsible for the BAG system.

Base registries

There are 10 base registers. Base registers have been officially instated by the government as the mandatory data registration sources for all governmental institutions when executing their public duties. Their application varies: from the turning out of emergency response services, and the efficient determination of a claim on benefits, to the appraisal of a license application. The citizen’s privacy is guaranteed when these data are used.

BGT

The Key register Large-scale Topography (in Dutch: Basisregistratie Grootschalige Topografie, BGT) is a digital map of the Netherlands, which records buildings, roads, waterways, land, and railway lines in a uniform way. The map is accurate up to 20 centimeters and contains many details, just as you would see in reality. In short, it documents the spatial organization of our physical surroundings: trees, roads, buildings.

BRI

The Key register Income (Basisregistratie Inkomen, BRI) contains the total income or taxable annual income of everybody who files an income tax return. Government organisations use the BRI to determine supplements, subsidies, or benefits. The income registered in the BRI is called the registered income. You can view your registered income (of the previous year) on MijnOverheid (MyGovernment).

BRK

The Key register Kadaster (Basisregistratie Kadaster, BRK) consists of the cadastral registration and the cadastral map (Kadastrale Kaart). The cadastral data are used by many clients as the foundation for their own work processes. In that sense, the Kadaster has been a key register for a long time. The Kadaster’s products remain available through MijnKadaster and the other channels. Direct links to other key registers will enable incorporation of the data of other registers into the cadastral register and products.

BRO

The Key register Subsoil (Basisregistratie Ondergrond, BRO) is to become the central database containing all public data on the Dutch subsoil. The BRO Act, which came into effect on 1 January 2018, requires that source data owners provide and use soil and underground data in a digital form. The requirements will be expanded step by step in the next 4 years. The data in this key register have been validated and are of importance for activities like fresh water procurement, underground transport, and mineral mining, but also for activities on the surface, like energy transition, housing construction, and infrastructural projects.

BRP

The Key register Persons (Basisregistratie Personen, BRP) is the key register for personal data within the key register system. The Dutch government uses the data recorded in the BRP. Amongst other things, these are: name, date and place of birth, address, and familial relations. Other organizations also use the BRP data, for instance pension funds and research institutions.

BRT

The Key register Topography (Basisregistratie Topgrafie, BRT) consists of digital topographic files on different scale levels (scale: 1:10.000, 1:50.000, 1:100.000, 1:250.000, 1:500.000, and 1:1.000.000). The Netherlands Cadastre or Kadaster manages the BRT. This collection of topographic files is available as open data. This means that the Kadaster makes these data files available free of charge, and subject to minimal delivery conditions.

BRV

The Key register Vehicles (Basisregistratie Voertuigen, BRV) lists data of vehicles, vehicle registration documents, and persons to whom the vehicle registration document was assigned. The Netherlands Vehicle Authority (RDW, Dienst Wegverkeer) provides information from the register to authorities, citizens, and businesses.

Digikoppeling

Digikoppeling (‘Digilink’) consists of standards for interfaces, containing agreements for the exchange of messages between authorities. One Digikoppeling implementation in an IT-environment enables you to exchange messages with all authorities, and to join nearly all eOverheidbouwsstenen (e-Government Building Blocks), for instance the key registers. Governmental as well as private organisations that perform a public task can use Digikoppeling.

Digilevering

Digilevering (‘Digidelivery’) is one of the system services. Digilevering distributes up-to-date and accurate key register data to key register clients in the shape of event messages, for instance relocation of a company, the birth of a person, or a change in somebody’s income. Each receiving organization is responsible for determining which data are relevant.

Digimelding

The information stored in key registers has to be up-to-date and reliable. One of the tools used to guarantee the quality of the key registers is Digimelding (‘Diginotification’), which enables users to ‘report back’. All users of the key registers have a legal duty to report any data that they know could be wrong. Reporting back contributes to efficient operations management within the government, improves the level of service, and increases the opportunities to fight fraud.

HR

The Trade Register (Handelsregister, HR) is the base register containing all businesses and legal entities. All other economic actors are also listed in this register. This guarantees legal security when doing business. All government bodies will we required to make use of this register. For instance, a municipality will have to consult the Trade Register when searching for a company’s details.

NORA

The purpose of the Netherlands Government Reference Architecture (Nederlandse Overheid Referentie Architectuur, NORA) is to be a guiding and driving tool. It contains frameworks and existing agreements for the lay-out of the Dutch governmental information management system. Realising services within the scope of these frameworks and agreements ensures smooth cooperation with other services, and optimal re-use of existing solutions.

System Catalogue

Data from the key registers form the axis for multiple use of data within the government. The System Catalogue makes visible which data the Key register System contains, what they mean, and how they are interconnected. The System Catalogue is targeted to inform policy makers and legislation lawyers.

System services

The smart exchange of data from the System of Key registers enables the government to operate more efficiently and to improve its service. Four System service support the key registers in their aim to disclose their catalogue of products and services to users in a uniform way. The System of Key registers identifies the following System services: Digikoppeling Digimelding Digilevering Stelselcatalogus.

WOZ

The data collection for the Key register WOZ (Waardebepaling Onroerende Zaken, or Valuation of Immovable Property) consists of several data, needed to relate this value both to an immovable property and to a stakeholder. These are: “Established value”(WOZ value), a BAG-listed address, and a link to cadastral parcels and/or addresses, and to BAG dwellings, stations, berths, and/or objects.
