Dutch obligatory use of base registers

In the Dutch public sector, mandatory usage of base registers is an important e-government principle enhancing the quality of provided services to citizens and businesses. By law, data about (among others) citizens, addresses and businesses must be re-used across different government domains and organisations. For quality improvement purposes, (suspected) data flaws have to be reported to the data source of the base register.

Introduction and management of this required base register compliancy poses potential problems to Dutch public organisations, each responsible for their own information- and application architecture. Any compliancy or synchronicity deviations between distributed registers across organisational departments and common registers can have a direct effect on service providing or have financial implications. 

Measurement system i-Spiegel®

i-Spiegel® is a decentralised, independent measurement system with which Dutch (public) organisations can measure compliancy and synchronicity of their distributed data with base registers. These measurements (analyses) can be performed with 3 separate algorithms:

  • based on citizens personal data (base register personal data)
  • based on address/location data (base register addresses)
  • based on organisation data (base register organisations)

i-Spiegel analyses can help organisations to improve their data- and information management. Users of i-Spiegel adopted this system because it exposes technical (ICT), process and organisational shortcomings within and between organisations. Besides that, i-Spiegel usage can gain insight in specific (financial) cases, triggering management to improve usage of base registers. For example, i-Spiegel can be used to map possible financial gain by not sending invoices to non-existent addresses. Or by not paying social welfare to non-existent (deceased or migrated) inhabitants of a municipality.  

How it works

The i-Spiegel system consists of 2 components: i-Spiegel software and this i-Spiegel website.

Organisations use i-Spiegel software locally to analyse data. Each analysis has to be made to fit; population selection, data selection and choice of algorithm have to be defined to meet research objectives. In the Netherlands, KING developed 15 standard analysis definitions for municipalities, using locally and centrally obtained data sets (among which bases register data).

Each analysis delivers local encrypted metadata. These have to be traded for a decryption-key on www.i-spiegel.nl. Usage of this decryption-key within the software, releases locally detailed data analysis results. These detailed results gives compliancy and synchronicity information of each researched record with respect to data in base registers, in a white-box manner.

Uploaded metadata in www.i-spiegel.nl are not being disclosed as semi-open data yet.
