Authentic Data - Public Master Data Management in Denmark

Public Master Data – Part of the new Strategy

Background

• The public sector in Denmark enjoys high levels of trust from citizens and enterprises

• Denmark has a long tradition of efficient registration of citizens, property, enterprises

• These registries (CPR, CVR, BBR etc.) has developed over 30 years as “silos”, catering to the needs of their respective mandates

• A small subset of data concerning geography, cadestra, buildings, people and business´ has been chosen as the Public Master Data (“Grunddata”)

• In the fully digitized public sector these Public Master Data are de factothe data-infrastructure of the service-oriented public sector

• Therefore, new policies and technologies must be put in place tomanage these registries as a coherent set of Public Master Data

The Vision

• Authentic Data (”Grunddata”) as a common and coherent data-infrastructure for

the public sector institutions

• Sufficient high quality of the Authentic Data

• Authentic Data is updated one place and distributed from the one place (though

not the same…)

• Authentic Data is re-used by all authorities in the relevant systems and processes

We must build bridges between the data-islands…

Gains from Better Public Master Data Management

More efficient distribution of Public Master Data

More efficient production of Public Master Data

More efficient use of Public Master Data

Public Master Data Challenges in Denmark

1. Lack of coherence between sets of Public Master Data (”Data-islands”)

2. Insufficient quality in some parts of the Public Master Data

3. Lack of technical availability of Public Master Data

4. Pricing and licensing of the Public Master Data Lack of cross-government governance of Master data

5. High level and continued governance of the Public Master Data

Islands of data

To enable reuse of data, ”bridges” between datasets must be established

It works, but…

Road-map for coherent Authentic Data

Technical challenges to more efficient use of Public Master Data

• Lack of high availability (24/7/365) of Public Master Data

• Different SLA, interfaces, licenses, service-windows makes integrating Public Master Data from multiple sources time-consuming and expensive

• Exponential increase in use of public data sources (eg. geografic data) puts a financial and technical strain on the many platforms for distribution Public Master Data

Pricing of Public Master Data

• Historically registries has been making “their own money” from sale of data to public and private sector institutions

• Some registries now has a compulsory subscription for public sector institutions

• This model improves reuse of data in public sector

institutions, but the need to protect the private sector

marked for sale of data inhibits reuse in the public sector

• Pressure to make access to data free of charge for private sector to spur growth clashes with strained public sector finances

• Economic analysis of alternative charging-models for 6 selected sets of Authentic Data: Maps, Cadestra, Business (3 datasets) and Persons
