General Information

OOP Enabling Infrastructure
The MAGDA platform is a once-only principle implementation supporting electronic delivery of public services, at the federal, regional, and local levels of the government.
Short summary
"The MAGDA platform provides one common service-oriented data exchange infrastructure for the 190 agencies and 13 departments of the Flemish regional Government, and for the 308 local governments. The MAGDA platform provides access to base registries of citizen and enterprise data, harnessing reusable technologies that can be easily adapted to the needs of different government administrations, from the regional to the local level, and increasingly to the federal level.
The MAGDA platform allows for the retrieval of data from base registries (federal and Flemish) and the exchange of data. The platform was built to realize the principle of the "once-only” collection of data, as well as the multiple (re)use of data. Data entered (for the first time or updated) by citizens and businesses are collected only once. All applications that later want to use these data can retrieve them from the available base registries and so always use the latest information.
Through the MAGDA platform base registries (both federal and Flemish) are connected. And this despite the different structure of the data sources and the different design of the applications using them. The following base registries amongst others are now interconnected by the platform: the National Register, the CBSS (Crossroads Bank for Social Security), CBE (Crossroads Bank for Enterprises) and LED (Database of certificates of learning and of professional competence). The platform also offers data from other data sources which can be considered as authoritative sources. The data provided comes from more than 25 other sources, including information on vehicles, work permits, integration of refugees, education information or school attendance.
MAGDA’s reusable services allow government organizations to quickly and costeffectively integrate data from these sources into their processes and applications.
The implementation of the platform was instrumental in the change from a “pull” to a “push” government, i.e. from a type of government in which citizens and businesses have to actively ask for services to a type of government that can proactively inform them about the benefits they are entitled to, on the basis of the data the government already has about them.
The use of the MAGDA platform has steadily increased over time, to the point that it currently connects more than 25 data sources and provides more than 75 data services."

External impacts
The MAGDA platform was used in building the ANTWERP "Low Emission Zone" , as it allows to check for each vehicle coming into the city it's technical specifications (fuel type, Euro Standard..)
Lessons learned
MAGDA was built without a big major plan which would have taken years of negotiations with all administrations involved. It was built incrementally adding new services "on demand" of concrete projects Flemish administrations and local governments wanted to realize. Of course scalability was foreseen from the beginning. In this way there was no big investment demanded at the start, we built it over a period of 10 years spending 3.5 million € annually.
