Data models map knowledge


Joint Public Sector Steering Committee working in spring 2017 to develop a new set of regulations for concept modelling and data modelling.

The Joint Public Sector Steering Committee’s work is focusing on further developing the model regulations for basic data generated in the Basic Data Programme. Based on the model regulations, the Basic Data Programme has created a common data model illustrating relations between individual registers in the Basic Data Programme.

Mapping relations

The basic data model has mapped the location of data and relations between data in the model. This enables users and developers to see relations between data recorded in different registers in the Basic Data Programme.

For instance, the mapping may show that a person owns a specific business, and that this business is located in a building with a basement and a balcony at a specific address. Other businesses with other owners are located in the same building at this specific address as well. Previously, it was up to the user to find and combine this information, because the information contains personal data, business data, property data, and address data from different registers. However, with the data model, the relations between the data have been mapped.

In other words, finding and mapping data used to involve a good deal of detective work, but today this task is solved by the data model.

Simplicity for citizens and users

ATP (an organization administering key welfare benefits and schemes on behalf of the Danish public sector) is a major user of basic data. Peter Tranto Bräuner, director at ATP, said:

”The basic data model offers a range of advantages to ATP in the long term. The model provides a uniform and shared understanding of concepts, which facilitates reuse of data across public authorities and private businesses in the long term. For citizens, this makes for a simpler procedure, because data no longer has to be recorded in many different registers, and at ATP we now have a full and clear overview of the data we’re dealing with.”

Next generation

Work on the next generation of model regulations is based on experience from the Basic Data Programme and has already been initiated. The next generation will have special focus on clarification of concepts. The agreed concept must be used in legislation as well as in ICT systems. Therefore, it is essential to make it absolutely clear what a concept covers in order to avoid ambiguities, as well as loopholes in legislation. For example, the definition of the concept of income must be clear.

Dialogue on model regulations

The Joint Public Sector Steering Committee developing the next generation of model regulations has prepared and published a White Paper on digitisation architecture, as well as a set of regulations for concept and data modelling.

On behalf of the Steering Committee, the Agency for Digitisation has invited interested parties to a dialogue on the White Paper and the regulations.

As the next steps in the Basic Data Programme, the updated hydrological elevation models will be included in the Digital Map Supply, and CVR (the Danish central business register) will be included in the Data Distributor (the shared distribution platform). This will happen in the spring of 2017.
