DESCRIPTION: It is an interoperable european solution, developed by, or in behalf of, an European public administration that enables the delivery of a digital public service, all of it, in fulfilment of a shared European legislation framework, being managed according a shared governance framework, accessing semantic assets in a shared knowledge base and using digital resources of a shared platform enabling cross-border/cross-organization exchange of data, information, and knowledge indistinctly between public administrations, businesses and citizens in support to the implementation and advancement of an EU, national or local public policy. Based on ISA TES definition https://joinup.ec.europa.eu/node/149889 IoP Dimension: Structural IoP, Behavioral IoP EXAMPLES: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): eDelivery Supporting secure and reliable exchange of data and documents eDelivery is a network of nodes for digital communications. It is based on a distributed model where every participant becomes a node using standard transport protocols and security policies. eDelivery helps public administrations to exchange electronic data and documents with other public administrations, businesses and citizens, in an interoperable, secure, reliable and trusted way. eDelivery is one of the building blocks of the European Commission's Connecting Europe Facility (CEF). These building blocks are reusable specifications, software and services that will form part of a wide variety of IT systems in different policy domains of the EU. The CEF eDelivery building block is based on the AS4 messaging protocol, open and free for all, developed by the OASIS standards development organisation. To ease its adoption in Europe, eDelivery uses the AS4 implementation guidelines defined by the Member States in the e-SENS Large Scale Pilot. Organisations must install an Access Point, or use a Service Provider, to exchange information with the AS4 messaging protocol. https://ec.europa.eu/cefdigital/wiki/display/CEFDIGITAL/eDelivery
