In the European Commission, the Directorate General focused on Information technology is called DIGIT. Today we talk with Joao RODRIGUES FRADE head of sector for the Building Blocks in DIGIT. A Building Block is an open and reusable digital solution that can be used by a SmartCity or a smart government. Smart cities such as Vienna Austria or Caragena Spain and Smart Governments such as Estonia or Italy, use the DIGIT building blocks. These Building Blocks are of course endorsed by the European Commission and are very helpful to enable a smart city to accelerate its digital services.
