The purpose of this deliverable is to take stock at the existing eGovernment landscape in Europe for
implementation of eServices and cross border enablers, identifying existing national eGovernment
capacities, major setbacks and potential drivers for the project implementation. The study covers the
domains of Electronic Identification, Authentication and Trust services (eIDAS), Single Digital Gateway
(SDG), Digital Service Infrastructure (DSI), Once-Only Principle (OOP) and Data strategy. Whilst the
present report majorly focuses on the first three domains, the deliverables D1.3 “Member State Once
Only and data strategy Baseline” and D1.5 “Baseline EU Building Blocks supporting Once Only and
standard data sharing patterns” suggest insights onto OOP, Data Strategy and existing EU Building
blocks respectively. The study was based on the data derived from a survey (see more details in Section
2.3), which was distributed among the EU and the EFTA countries. The quantitative analysis from the
study was complemented by desk research.

The purpose of the present deliverable (D1.2) is to provide a current overview and analysis of the
eGovernment landscape in Europe. In that sense, it is a continuation of a previous effort to provide an
initial view of the European eGovernment services at the beginning of DE4A. The current report
focuses on the means for implementation of e-services and cross-border enablers, identifying existing
national eGovernment capacities, major barriers and potential drivers, and establishing a general
picture on the implementation levels of the current legislative and technological efforts concerning
the eGovernment services. To do that, the study revisits the eGovernment landscape in the domains
of Electronic Identification, Authentication and Trust services, and European Digital Wallets (eIDAS /
eIDAS v2), as well as the state of implementation of Digital Service Infrastructures (DSIs), the Single
Digital Gateway (SDG), and the Once-Only Principle (OOP). The major part of the study is based on data
derived from an extensive survey (see Annex: DE4A Survey, and Section 2.3 for more details), which
was distributed among the EU and the EFTA countries. The data analysis from the study was
complemented by semi-structured experts’ interviews, additional data sources that complement the
survey dataset, as well as a thorough literature review / desk research.

The purpose of this deliverable is to take stock of the existing eGovernment landscape in Europe for
implementation of eServices and cross border enablers, identifying existing national eGovernment
capacities, major setbacks and potential drivers for the DE4A project implementation. The study is part
of a series of 4 studies covering the domains of Electronic Identification (eID), Authentication and Trust
services (eIDAS), Single Digital Gateway (SDG), Digital Service Infrastructure (DSI), Once-Only Principle
(OOP) and Data strategy, the latter two being the focus of the present study.

The purpose of this deliverable is to take stock of the existing Once Only capabilities at national and
cross-border level, as well as national data strategies referring to access provisions to base registry
services. As one of the four related studies: D1.2 Updated Member State eGovernment Baseline, D1.6
Updated EU Baseline Building Block Catalogue, and D1.8 Updated Legal, technical, cultural and
managerial barriers, this report approaches the topic in a multifaceted manner, establishing
interdependencies with the current regulatory EU efforts while providing empirical evidence of the
implications. As such, it supports the implementation of the SDG and OOP and positions them at the
core of the Europe’s digital transformation.

The project Digital Europe for All (DE4A) was launched in January 2020 as a result of collaboration of
27 organizations from 11 countries of the European Union. The project is funded by the EU Horizon
2020 research and innovation Framework Programme and is aimed to create an inclusive digital
Environment in Europe ensuring the Single Digital Market rights of citizens and businesses by building
on secure, privacy-preserving and trustworthy realisation of fundamental once-only, relevant-only and
digital by default principles. The DE4A large-scale pilot reinforces the connectivity of national digital
endeavours and, building upon the existing infrastructure, it attempts to contribute to an overarching
eGovernment network for Europe supporting parallel efforts from the EC and the Member States to
realise the Once-Only Principle Technical System in compliance with Single Digital Gateway and aligned
with EU eGovernment Action Plan 2016-2020, Tallinn Declaration and EIF Implementation Strategy.

The purpose of this study is to take stock of the existing reusable Building Blocks supporting data
sharing, Once Only Principle and interoperability, enabling the implementation of services for citizens
and business in the European Union. This study is one of four studies designed to chart the current
landscape of digitalization in Europe. The initial studies in this series were: D1.1 Member State
eGovernment Baseline, which elaborated on the advancement of the existing eGovernment landscape
at the beginning of the DE4A; D1.3 Member State Once Only and data strategy baseline, which
analyzed the Once Only capabilities at regional and national level in the same period in terms of Once
Only capabilities related to cross-border services, national data strategies and generic access to base
registry services, and D1.7 Legal, technical, cultural and managerial barriers, which elaborated on the
drivers and barriers to the implementation of OOP.

The concept of a truly single market of digital services for cross-border citizens and businesses holds
tremendous potentials in terms of ease of life and economic gains. However, as with any significant
change, the process of bringing that concept to life may risk running the gauntlet, if not carefully
planned against the realities of the member states it bridges.
D1.7 supports the development of a single market for digital services by identifying the legal, technical,
cultural and managerial risks and barriers on the implementation of cross-border digital public
services.
In order to ensure a broad spectrum of risks and barriers are identified and properly understood, the
study draws upon three different kinds of sources: A survey among the Chief Information Officers of
the EU and EFTA Member States, a literature review of European projects, and focus group interviews
with a dozen experts from 10 different countries.

The architecture framework of the “Digital Europe for All” project (DE4A) provides the methodological foundation for the overall project. In addition, we propose a long-term architecture vision that should guide the development of the Once-Only Technical System to be a significant step towards a more encompassing ecosystem. It is a working document and will be updated with additional insights over the course of the project. Consequently, this first version is not a normative architecture document, but a contribution to the Once-Only Principle discussion in this project and other relevant initiatives, including the Connecting Europe Facility (CEF) preparatory action and the Single Digital Gateway (SDG) implementation. It is also an open invitation for comments and contributions extended beyond DE4A.

This deliverable is a first version of the design of the Trust Management Models and Blockchain
Support framework produced in the context of Task 2.2 “Trust Management Models” in “WP2
Architecture vision and framework”. This framework sets the basis in terms of trust management and
disruptive technologies adoption (such as blockchain) in DE4A. This deliverable serves as the key
design guidelines for the implementation of the DE4A Trust Management Model and Blockchain
Framework (D5.7 First Release of DE4A Blockchain Supporting Framework– Initial version).

The present document has addressed multiple aspects related with the establishment and maintenance of trust needed in relation to the five different evidence exchange patterns (intermediation, user support intermediation, verifiable credential, lookup, subscription & notification) defined and being implemented in DE4A in the context of the Single Digital Gateway and Once-Only Principle

The Project Start Architecture (PSA) provides a starting point and guidance to the three DE4A pilot
projects, which are essential in providing Evidence of the benefits of the full implementation of the
once-only and digital-by-default principles and user centricity and the transformative impact of new
technologies such as blockchain [16] and to WP3 - Semantic Interoperability Solutions and WP5 –
Common Components Design & Development that will develop common components and semantic
solutions for them. In parallel to this project, the SDGR [3] creates in Article 14 the basis for the first
truly cross-domain Once-only Technical System on European level. The preparations for the
implementation of the Once-only Technical System is well under way, led by the CEF Preparatory
Action on Once-Only. Consequently, more direct contribution of DE4A to this endeavour is of high
interest for internal and external stakeholders with continued alignment efforts geared to this effect.
The scoping of the DE4A pilots and the reference interaction patterns in this PSA show some focussed
on SDG use-cases and the OOP principle while extending to additional interoperability requirements
expressed by the participating MS and the investigation of the potential of innovative block-chain
technology. This is in line with the DoA. The PSA uses a structured architecture definition approach
and provides guidance on 22 interdisciplinary questions (2.3) concerning the exchange of evidence.

This document is the formal public delivery D2.5. It is a new, restructured, and shortened version of the PSA, considering recent developments and new insights in addition to two new interaction patterns. It is an extension of D2.4 (PSA first iteration) and defines the updated start architectures for the second iteration of the Pilots. Its content is also integral part of the deliverable D2.6 ‘Service interoperability solutions toolbox’ that is being compiled on the DE4A Wiki. Further insights and subsequent updates will be reflected there.

This document accompanies the DE4AWiki, which is in fact the real deliverable D2.6, the "Service interoperability solution toolbox" .
In the technical work packages of DE4A, as well as in the technical task team and in DE4A participating organizations, different levels and types of specifications and documentation were created during the project. This process is fraught with the risk that project documentation becomes scattered, and structuring attempts are more often than not too late to be effective. To prevent this, DE4A includes as part of WP2 Architecture Vision and Framework tasks, a deliverable aimed at maintaining a documentation overview and thus maximizing the value of all the specifications, documentation and guidelines that work packages produce: T2.4/D2.6 Service interoperability solution toolbox. This toolbox has been given the form of an online wiki, located at https://wiki.de4a.eu/index.php/DE4A_Service_Interoperability_Solutions_Toolbox .

Taking the first version of the Once-Only Technical System (OOTS) [18] (due 12.12.2023), as a starting point, a mid-term future, multi-pattern, target architecture is sketched in terms of high-level business processes and application flows. At this time horizon (2025+), the availability of the European Digital Identity (EUDI) Wallet is assumed.

One objective of DE4A is to envision different target architecture states at different time horizons that provide guidance to the further development of European governmental interoperability solutions and platforms. This deliverable presents a consolidated architecture vision for the long-term time horizon, specifically the time beyond this Digital Decade. The starting hypothesis is that the digital transformation of European administrations, national governments and public authorities has a profound impact on the development of the data-driven economy and the social and economic reality of the single market and its global competitive position.
The objective of D2.8 is to provide guidance and focus for architects and policy makers both on Union and Member State level. The authors attempt to put forward a positive, ambitious, yet attainable, architecture vision of the future of interoperability that transcends both national boundaries and classical roles of public administration, private and third sector.

This document assembles the initial requirements as far as semantic interoperability is concerned within the context of Digital Europe for All (DE4A) project. To achieve this, analysis of existing taxonomies and libraries of core vocabularies is performed. While this deliverable is focusing on the initial set of requirements for semantics in DE4A, it also defines a structured way of eliciting requirements with co-operation from other Work Packages (WPs), namely work package WP4 – “Cross-border Pilots for Citizens and Business and Evaluation” and work package WP2 – “Architecture Vision and Framework”, to provide design decisions and implementation guidelines to work package WP5 – “Common Component Design & Development”, and DE4A technical partners as well.

This deliverable exhaustively provides the final requirements as far as semantic interoperability is concerned within the context of the Digital Europe for All (DE4A) project. To achieve this, analysis of existing taxonomies and libraries of core vocabularies was performed, presented already in previous deliverable D3.1 ‘’Initial Requirements for Semantic Assets’’ [1]. While the present document focuses on the final set of requirements for semantics in DE4A, it also defines a requirements elicitation methodology that is important to be followed by similar initiatives in the future.

This document is a first version of the design of the DE4A semantic framework produced in the context
of Task 3.2 “Design of the semantic interoperability framework” in “WP3 Semantic Interoperability
Solutions”. This framework sets the basis for semantic interoperability needed for evidence exchanges
at a pan-European level of public service provision. This document serves as the key design guidelines
for the implementation of the DE4A Semantic toolkit (D3.5 Semantic Toolkit – Initial version).

This document is the final version of the DE4A semantic framework produced in the context of Task 3.2 “Design of the semantic interoperability framework” in “WP3 Semantic Interoperability Solutions”. This framework sets the basis for semantic interoperability needed for evidence exchanges at a pan-European level of public service provision. This document along with the deliverable D3.2 “Final Requirements for Semantic Assets” serves as the key design guidelines for the implementation of the DE4A Semantic toolkit (D3.6 “Semantic Toolkit – Final version”).

This document is an initial version of the implementation of a toolkit for the semantic layer stack in the context of Task 3.3 “Implementation of the semantic tools” for delivering cross-border public services. This implementation process follows an agile methodology, by starting in a baseline level with D3.1 “Initial requirements for semantic assets” and D3.3 “Initial version of the Semantic framework” and incrementally improving by adding the tools resulting from the pilot requirements and the other emerging assets identified and added in these live documents.

This present deliverable is the final version of the DE4A toolkit developed for the semantic layer stack in the context of DE4A WP3 “Semantic Interoperability Solutions” for delivering DE4A cross-border public services. The document provides an updated version of the DE4A toolkit that was presented in D3.5 “Semantic Toolkit – Initial version” [6].

The implementation of the Once-Only Principle (OOP) for public services at European level faces a great challenge: semantic interoperability. To a large extent, cross-border semantic interoperability has been addressed by developing common data models and formats for the information to exchange. This, however, is not a simple task and need to solve many other issues in order to achieve semantic interoperability in this context. Could Artificial Intelligence (AI) help in providing a coherent semantic interoperability for cross-border public services?

The Studying Abroad pilot of the “Digital Europe for All” (DE4A) project aims at demonstrating in practice the benefits for different European Higher Education Area stakeholders of realizing across borders the principles of Once Only and Digital-by-Default. By the combination of three use cases (Application to public higher education, Applying for study grant, and Diploma recognition) it will prove the optimal process/procedure for students of the participating three Member States (Belgium, Slovenia, and Spain) for registration and eventually applying for a student grant as well as for studies recognition.

The Studying Abroad (SA) pilot of the “Digital Europe for All” (DE4A) project focuses on Higher
Education students with virtual or physical mobility needs in the European Higher Education area. By
piloting three use cases (UC#1 - Application to public higher education, UC#2 - Applying for study
grant, and UC#3 - Diploma recognition) it aims to prove the optimal process/procedure for students
from the three participating Member States (Portugal, Slovenia, and Spain) for registration to higher
education and eventually applying for a student grant as well as for studies recognition. The pilot will
run in two iterations, the first from October 2021 to the end of January 2022, and the second from
May 2022 to the end of October 2022.

This document reports the progress achieved in the pilot in the first iteration until the end of February. Following an internal development plan described in D4.2[2], pilot-specific Data Consumers and Data Providers have adapted their procedure and evidence portals and data services (Data Evaluators, Data Owners) and implemented the activities required to connect their infrastructures (eIDAS pre-production nodes, national OOP Technical System) to the respective common building blocks and components for interoperability across borders (DRs, DTs). In coordination with “WP3 Semantic Interoperability Solutions” and “WP5 Common Development Design & Development”, common building blocks and components have been integrated and tested prior to the first go live of the pilot.

The Studying Abroad (SA) pilot of the "Digital Europe for All" (DE4A) project aimed at demonstrating in practice the benefits for different European Higher Education Area stakeholders of realizing across borders the principles of "Once Only" and "Digital-by-default". By the combination of three use cases (UC#1 - Application to public higher education, UC#2 - Applying for a study grant, and UC#3 - Diploma recognition) it validated during two iterations adding 12 months of cross-border piloting in realistic operational environments online processes/electronic procedures for students of the three participating Member States (Portugal, Slovenia, and Spain), for registration to higher education and eventually applying for a student grant as well as for studies recognition.
In the project's final running phase, realising progress from the initial Minimum Viable Product to fuller extended scopes, the pilot partners focused on monitoring pilot running services, gathering data and feedback from all stakeholders (Data Evaluators, Data Owners, Member States, and students), and providing support to pilot users. Use cases were officially launched after the different testing phases (of common infrastructure interoperability components and the connected pilot services) were successful and the necessary trust conditions were satisfied.

The Doing Business Abroad pilot of the “Digital Europe for All” (DE4A) project demonstrates the benefits of the Once Only Principle and the Digital by default principle for companies and public authorities cross-border. In two use cases – Starting a business abroad and Doing business abroad – the pilot validates the Once-Only process for enrolment of a company and applying for services in another country (online procedures listed in Annex II of the SDGR under the Life Event “Starting, running and closing a business”). In some of the envisaged piloting scenarios, the company (‘s branch) enrols to the authentic business register of the data consuming Member State. In other scenarios, the data consumer operates a portal-specific company registration (non-authentic). The piloting Member States are Austria, Belgium, the Netherlands, Romania and Sweden.

This deliverable specifies the design of the Doing Business Abroad (DBA) pilot and provides a plan for
managing all activities in the upcoming two phases: customization and integration phased and pilot
running phase. It provides a sound basis for the piloting Member States to perform the tasks to
customize and integrate the components, test the components, involve real users and run the pilots.
As none of the piloting Member States can run a pilot without at least one other Member State, central
to this document is pilot alignment: making sure Member States converge their activities at predefined milestones.

This document embodies the intermediate report on the DE4A Doing Business Abroad pilot, providing preliminary conclusions and lessons learned from piloting the cross-border exchange of information in the context of the Single Digital Gateway. It is the first of two reports on this matter, covering preparatory activities towards real-life piloting the use cases for the Doing Business Abroad pilot. Preparations include the analysis on major topics (like use of eIDAS, company representation and interaction patterns), deployment of DE4A common components, integration into Member State specific solutions, testing of integrations between Member States and common infrastructure components, and involving companies to participate in the pilot.

Report on the DE4A Doing Business Abroad (DBA) pilot, providing final analysis of results obtained, conclusions and lessons learned from piloting the cross-border exchange of information in the context of the Single Digital Gateway (SDG). It completes preliminary reporting of results, lessons learned and conclusions from D4.7 Initial running phase report. DBA successfully piloted in real-life conditions two use cases along two iterations running respectively from May 2022 to July 2022 and from October 2022 to January 2023. Use Case 1 concerns registering a new business activity in another Member State (using the intermediation pattern), while UC2 focuses on the possibility for Data Evaluators (DE) to stay informed about changes in the foreign companies that registered a business activity with them (using the Subscription & Notification pattern).

The main goal of the Moving abroad pilot is to facilitate the evidence exchange when citizens are moving abroad. The benefits of this will be fewer physical movements of citizens to fetch the evidence and less interventions of civil servants resulting in a faster evidence exchange. In general terms the requirement of the pilot is to deliver evidence online, in real time in a structured (data) format to the citizen as part of a procedure that is related to an address change, a request for a birth, marriage or death certificate or a request for pension information and/or a pension claim when moving abroad. As a prerequisite of this, the citizen will have to be authenticated via eIDAS and linked to the evidence via a national registration number of the foreign country. In some cases, civil servants will intervene to link the citizen - based on this eIDAS identification - to the national number.

The Moving Abroad (MA) pilot of the DE4A project, implements eProcedures for moving and living
abroad in Luxembourg, Portugal, Romania, Slovenia, Spain and Sweden. It improves currently available
cross-border procedures by implementing the Once Only Principle (OOP).
This deliverable specifies the design of the MA pilot and provides a plan for managing all activities in
the upcoming two phases: customization & integration phase and pilot running phase. Both phases
will iterate twice, having a first iteration with an initial scope and sequentially a final iteration with an
extended scope.

The Moving Abroad (MA) pilot of the DE4A project implements electronic procedures for moving and
living abroad in Luxembourg, Portugal, Romania, Slovenia and Spain. It improves currently available
cross-border procedures by implementing the Once Only Principle (OOP), going from weeks of work
to hours or at most a few days. This deliverable is the first of a series of two reports which describes the implementation and customization of Member State specific solutions where common DE4A components have been deployed and their integration tested as part of preparatory activities towards the first iteration of the real-life piloting. It also provides preliminary conclusions and lessons learned from piloting the crossborder exchange of evidence for citizen-oriented procedures in the context of the Single Digital
Gateway.

This document is the final report on the DE4A Moving Abroad pilot, providing conclusions and lessons learnt from piloting the cross-border exchange of information in the context of the Single Digital Gateway Regulation (SDGR). The Moving Abroad (MA) pilot implements fully online electronic procedures for moving and living abroad realising across borders the principles of "Once Only" and "Digital-by-default" between Luxembourg, Portugal, Slovenia and Spain , aiming to demonstrate tangible benefits for citizens and administrative users.

This is the first deliverable of the task of DE4A’s “Cross-border Pilots for Citizens and Business and Evaluation”, corresponding to the Mid-term Evaluation of the achievements and results obtained so far -with respect to pilot and project objectives- for the three DE4A Pilots: Studying Abroad (SA), Doing Business Abroad (DBA) and Moving Abroad (MA). These pilots act as point of convergence for results of the whole project and serve the purpose of demonstrating the extent to which DE4A technical and semantic concepts, architectural models, building blocks and interoperability enablers can be successful when put to test for their intended use, under realistic conditions and with direct involvement of real users and eGovernment authorities. The ambition is that the knowledge and hands-on experience of the pilots serve the community of practitioners at European Commission C and Member States levels

This is the final deliverable of the task of DE4A's "Cross-border Pilots for Citizens and Business and Evaluation", corresponding to the Final Evaluation of the achievements and results obtained through the piloting phases -with respect to pilot and project objectives- by the three DE4A Pilots: Studying Abroad (SA), Doing Business Abroad (DBA) and Moving Abroad (MA). The Final Evaluation acts as an ex-post strategic point at the end of the project, having already assessed in the Mid-Term Evaluation the solidness of pilots' respective set-ups towards execution of running phase activities and their ability to proof concepts and practical outcomes from other technical work packages and to realize tangible benefits

The following deliverable contains confidential information.

This deliverable provides the technical design of the interfaces between the DE4A components that facilitate the integration among different technologies used by Member States. These interfaces include the ones required to communicate with the Data Consumers, with the Data Providers and with the common intermediation components, such as the DE4A Connector and the components of the Information Desk (IDK) defined by “WP3 Semantic Interoperability Solutions”. D5.4 also defines the common specifications that must be known and complied with by all DE4A network participants to exchange messages, including DE4A-specific protocols and third-party protocols and components.

The following deliverable contains confidential information.

The present document is written in the context of DE4A work package "WP5 Common Component Design & Development" and under the task "T5.3 Construction of Common Products and Components & Change Management". The scope of WP5 is the design and development of all new common software components required for the pilot implementations, according to the outputs of "WP2 Architecture vision and framework" and "WP3 Semantic Interoperability Solutions" on architecture and semantic components, respectively. Task T5.3 builds high quality and optimized common services and components from scratch or by adapting building blocks included in the solution toolbox identified by WP2. The aim is to build components that enable and ease the evidence interchange, the integration with infrastructure components at MS level and the integration, function, and acceptance testing. This deliverable D5.6 describes the common components developed by WP5: the common libraries, the DE4A Connector, the DE4A Directory and the Central IAL. It also describes the DE4A Playground, a set of predefined and pre-deployed components designed to help pilot partners to onboard the DE4A network.

The following deliverable contains confidential information.

This deliverable describes the final version of the DE4A Self-Sovereign Identity Supporting solution that implements the Verifiable Credentials pattern, which is piloted in the Diploma Recognition use case of the DE4A Studying Abroad pilot. This use case validates the scenario where students request their diploma in the form of Verifiable Credentials issued from national Higher Education portals and, after storing these credentials in their mobile digital wallets, present them to the service providers to finish the procedure. The Diplomas use case is piloted in DE4A by students of three Member States (Portugal, Slovenia and Spain).

The present document is written in the context of DE4A work package "WP5 Common Component Design & Development" and under the task T5.5 Support and results packaging.
DE4A has released a set of common components for the cross-border implementation of the once-only principle that are listed in the deliverable. The deliverable also provides a guideline for external stakeholders to join the DE4A network for the
cross-border exchange of evidences with other members of the network. Essentially, participants would be required to get their own eDelivery certificates based on the PKI the network is using; to set up, install and configure the eDelivery SMP and the DE4A Connector; and, finally, to develop a final participant (consumer or provider of data) and integrate it with the rest of components to start exchanging messages.

WP6 “Sustainable impact and new governance models” aims to develop business and governance models for long-term sustainability and evaluate their direct impact on public administration (and indirectly on businesses and citizens). WP6 addresses not only the sustainability of DE4A project outputs, but also longer-term outcomes and wider impacts. It looks at a broader perspective by looking at the key factors, such as desirability, feasibility and sustainability of the future pan-European government collaboration, with the necessary business and governance models in place, and bearing in mind the existing European-level initiatives. This deliverable is the first formal output of WP6 for the DE4A project. Having this in mind, it considers initial vision and strategy to guide methodological choices, including interlinking of broader impacts to desired outcomes and specific project outputs.

This document sets out to design new DE4A generic models and give the Member States (MS) and other stakeholders a starting point for appropriation in roadmaps. The purpose is to start to consider and create policy recommendations based on business models and how this has implications on roles and responsibilities as well as how to start road-mapping to mitigate risks and barriers in addition to considered social and monetary benefits. Due to the profile of the implicated actors as Member States, DE4A WP6 “Sustainable impact and new governance models” focuses on Governance rather than Business models per se.

This deliverable outlines the key aspects for sustainability and governance of the DE4A results. Sustainability is referring to all actions needed in order to assure the long-term success of the project outputs. DE4A has explored and piloted how to create an effective and efficient implementation of the once-only principle (OOP) at European level for a useful digital Government transformation in order to boost the Digital Single Market. To this aim, existing and upcoming policies have been taken into consideration, as well as new policies for innovative approaches to enable an optimal implementation.

This deliverable is the second formal output of WP7 (Legal and ethical compliance and consensus building) for the DE4A project and aims to summarise all legal and ethical compliance activities undertaken in the course of the project, including any recommendations, draft texts, and legal and ethical best practices that were agreed between DE4A participants for the purposes of the project.

This deliverable is the third and final formal output of WP7 (Legal and ethical compliance and consensus building) for the DE4A project. It aims to summarise the legal and ethical compliance activities undertaken in the course of the project, including any recommendations, final texts, and legal and ethical best practices implemented in the project, in particular in the course of piloting activities. It also provides inputs for future legal and policy actions under the Single Digital Gateway Regulation, and highlights potential avenues for further legal action (as a part of the SDG, or more broadly in relation to e-government).

D.4 is the final output of the Legal and ethical compliance and consensus building workpackage of the DE4A project. Its objective is to capture the possibilities, requirements and opportunities for the sustainability of the project from a legal perspective. The report focuses on some of the realisations of the DE4A project that are more challenging to sustain from a legal perspective, principally because the project's general ambition is to explore and pilot optimal approaches to create effective once-only information exchanges, and to generally improve the efficiency and user friendliness of eGovernment in Europe, without necessarily focusing exclusively on the direct implementation of the EU legal framework (namely the SDGR). This has led to a number of useful innovations in the project, such as the multi-pattern evidence exchanges, the use of mobile wallets and verifiable credentials, and fine-grained powers validation - none of which have comprehensive and mature legal frameworks at the EU level at the present time.

This document defines the dissemination and communication strategy for the DE4A project. The
purpose of DE4A is to develop an open and comprehensive environment and platform for EU Member
States to support and meet obligations under the Single Digital Gateway Regulation, to consistently
deliver secure cross-border, high quality, fully online procedures under the Once-Only Principle (OOP).

This document is an introduction to the operational status of the website and social media. The deliverable itself is the website and this short report documents it. It is not intended to be a report, but rather an illustration of the style and structure of the DE4A website and social media at the beginning of the project. It discusses the rationale behind the graphic guidelines and illustrates these with screenshots from the website. The website is shown to be structured and well thought out at this early stage of the project and its development. Other social media channels which, by definition, take time to grow, are also illustrated

This document reports the detailed dissemination and communication activities, undertaken during
the first year of the DE4A project (January 1st 2020- 31st December 2020) following the strategy
described in the deliverable “D8.1 Project Dissemination and Communication Strategy”.

This document reports the detailed dissemination and communication activities, undertaken during year 2 of the DE4A project (January 1st 2021 to 31st December 2021) following the strategy described in the deliverable “D8.1 Project Dissemination and Communication Strategy”, and following on from “D8.3. Dissemination and Communication Activities Report M12”.
