Background information

About the 2020 ISA² action on Innovative Public Services: Future of CEF eDelivery and API guidelines for government

This project is about the following specific activities (major outputs) within the 2020 ISA2 Innovative Public Services (IPS) action:

  • Future of CEF eDelivery: extension of the CEF eDelivery building block with innovative technical approaches leveraging blockchain and REST APIs. This activity has the objective of developing and piloting relevant technical specifications and artefacts through the use by CEF eDelivery of a blockchain-based transactions’ log offered by the CEF EBSI building blocks, on the one hand, and the definition of a REST-based profile as a candidate profile for future inclusion in CEF eDelivery, in order to support new patterns of data access and data sharing, on the other. Should the pilots be successful, the CEF eDelivery building block will be enriched with these novel technologies. Every element will be modular so that it can be used in combination with the existing eDelivery AS4 profile or on its own.

  • API guidelines for government: a set of guidelines and specifications for establishing interoperable REST-based APIs for service invocation and publication of both open and protected data. Sample library implementation for API’s as well as software supporting central/core services such as service catalogues and service discovery could be also in scope.
