CEF building blocks offer basic capabilities that can be used in any European project to facilitate the delivery of digital public services across borders, while the Sector Specific DSI are projects that are supported by the CEF building blocks across policy domains. These are known collectively as CEF Digital.

The first release of the CEF Digital Portal enables users to discover the catalogue of building blocks, understand how they work and provides the software and services to successfully (re)use them. CEF building blocks include, among others, eDelivery which helps public administrations to exchange electronic data and documents and eID which helps public administrations and private online service providers to easily extend the use of their online services to citizens from other EU Member States

Forthcoming releases will allow for enhanced collaboration between users and user groups and an effective management of information about projects. This will include different levels of access to the platform, depending on the user group and ensure user-friendly information exchange.

The building blocks have been developed and piloted over a number of years within the EU. The Portal, having been devised in close collaboration with the CEF Digital community, will assist in the continued development and reuse of the CEF building blocks across Europe.
