The Once-Only Conference for Europe will take place on 24-25 September in Vienna, Austria, and will be the second event devoted exclusively to the Once-Only Principle (OOP). The event is co-organised by two projects: TOOP and SCOOP4C, which are striving to explore and demonstrate the Once-Only Principle across borders from two perspectives: businesses and public administrations (TOOP) as well as European citizens (SCOOP4C).

At these conference will be presented the achievements of the projects and explained how the implementation of the principle will benefit to all participants of the European Digital Single Market. The core idea of the OOP is that e-service users will be providing data to public administrations only once. The data then is safely stored and exchanged between various authorities in different countries, resulting in streamlined provision of digital public services across borders. This will make life of European businesses and citizens easier, as well as reduce costs for public administrations.

The event will host speakers from European Commission, experts from TOOP and SCOOP4C projects as well as a range of stakeholders, including representatives of the countries, which are already working on the initial implementation of the OOP. During the first day of the conference, SCOOP4C and TOOP will present the main achievements of the projects; conference participants will be able to participate in a world cafe session and discuss the most relevant topics concerning the impact of the OOP on the Digital Single Market.

The second day will focus on high-level discussions of the OOP environment in the European Union. Relations to the Single Digital Gateway Regulation and the impact of the General Data Protection Regulation will be discussed. A number of case studies of OOP implementation within and outside of the EU will also be presented, followed by a panel discussion on the impact of OOP in the EU.
