FEDICT, the Federal Public Service for Information & Communication Technology, is within the Belgian Federal Government responsible for defining and implementing an e-government strategy. Furthermore FEDICT defines, in cooperation with the other departments, standards for improving interoperability and Government-to-citizen (G2C) and Government-to Businesses (G2B) communication. Creating a 'virtual' government through an integrated Federal 'back-office' and integration across different government levels is one of the key principles in our e-government strategy. Therefore open specifications and/or open standards are a prerequisite.
