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 LSP (e.g.: TOOP, PEPPOL, STORK, STORK2) and aims to be comprehensive at the level of European technical interoperability. It includes new DE4A common components and implementation method and Pilot insights.

Pilots

DE4A includes three cross-border and cross-domain Pilots - Studying Abroad, Doing Business Abroad, and Moving Abroad -, 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 Project Start Architecture - Second iteration is meant to introduce two additional Reference Interaction Pattern: the Subscription and Notification Pattern and the Lookup Pattern.

Library of components and building blocks

This section contains the collection of technical and semantic common components and candidate Building Blocks that are relevant for eGovernment interoperability in general and digital-by-default procedures and the Once-only Principle in particular. 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. You will find on each Application component pages a list of relevant DE4A common components, candidate Building Blocks (e.g. CEF) and memberstate solutions that jointly or alternatively realize that Application component.

Application collaborations:

Connector... -> to integrate in the correct Application component page

Common Libraries... Mock... Playground... -> I guess we need a section on "development and testing environment"
