Overall objective of the project

• exploring and demonstrating the "Once-Only" principle through several sustainable pilot solutions using a cross-border architecture at European level.

Project description

According to the "Once-Only" principle (OOP), in the context of public services, citizens and businesses provide data to a public administration only once. Public administrations take steps to share these data at national and cross-border level, so that citizens and businesses do not have to provide them several times for different procedures.

The implementation of the project involves the interconnection of 59 computer systems in 20 countries. Throughout this process, legal and administrative barriers have been identified at national level. Pilot solutions are innovative because they include products and services that are not currently available on the market and also provide a basis for future large-scale implementations of PPE.

Planning and deployment of pilot solutions is based on the Once-Only Generic Architecture (TOOPRA), which represents the main technological innovation of TOOP. This architecture is made up of several reusable architectural blocks that support the interconnection and interoperability of registers national level at EU level using an exploratory and agile methodology.

Given that the TOOP project has the mission to support the implementation of the Single Digital Gateway Regulation (SDGR), the architecture has been aligned with the SDGR and contributes to the development of the implementation document for this regulation. At the same time, TOOPRA is aligned with European Interoperability Reference Architecture (EIRA) and digital services provided by the Connecting Europe Facility (CEF), supporting the interconnection and interoperability of national registers at EU level.

The benefits of implementing the solutions developed within the TOOP project are to streamline data sharing, reduce bureaucracy and costs for business and public administrations in the European Union.

Results

• implementation of three pilot solutions:
  • cross-border e-services for business mobility;
  • updating company data;
  • ship and crew online certificates.
• developing a generic and federated OOP architecture;
• exploring the various legal and sustainability aspects of OOP.
