DE4A Service Interoperability Solutions Toolbox

This toolbox is the central, long-term deliverable of the DE4A Architecture work package (WP2) and takes the form of a structured, online architecture repository that extends from the content of the Architecture Framework and prior work of e-SENS. The toolbox includes (pointers to) prior work in CEF, ISA, ISA² and prior LSPs. It includes new DE4A common components and implementation method and Pilot insights.

Pilots

DE4A includes three cross-border and cross-domain Pilots - Studying Abroad Pilot, Doing Business Abroad Pilot, and Moving Abroad Pilot -, comprising different functional use cases focused on different high-impact and viable administrative procedures, and aimed to realize tangible benefits in fully operational environments to real users (citizens, students, business persons and public servants). The Pilots are delivered by a separate, agile, multi-disciplinary, inter-member state teams of experts. The focus of these teams is on iterative system integration and configuration, hence on making existing building blocks and solutions work together in real life cases.

Reference Architecture

DE4A develops a multi-pattern architecture for eGovernment interoperability with a focus on digital-by default procedures for citizens and businesses and the full implementation of the Once-Only Principle. The DE4A Architecture Framework defines five architecture Time Horizons staring from the pre-SDG baseline (t=0, ~2019) and reaching to a long-term vision (t=4, ~2030+) in order to place different developments in context. More detail on the Architecture Framework is available in the public deliverable D2.1 Architecture Framework.

The development of the DE4A Reference Architecture started in the context of D2.4 Project Start Architecture (PSA) - First iteration and recognizes three distinct Reference Interaction Patterns:

The forthcoming D2.5 Project Start Architecture (PSA) - Second iteration is introducing two additional Reference Interaction Pattern:

The Architecture Log keeps track of deviations from DE4A principles and the reference architecture in general and also records the implications.

Library of components and building blocks

This section contains the collection components and candidate Building Blocks. The classification of this library follows the DE4A Reference Architecture, starting on the highest level of architecture components: the Application Collaborations. These Application collaborations are aggregations of Application components, Data objects and Interfaces.

DE4A Solutions

The DE4A Solutions are split in Semantic Interoperability Solutions and Common Components. The first deals with semantic specifications, the second with SW components. There is also a link related to development and testing activities.
