Once-Only Technical System Projectathon #2 Insights

On 14-16 June 2023, the second Once-Only Technical System Projectathon brought together all 27 EU Member States for a marathon of peer-to-peer interoperability testing. This was the second of three such events planned to take place in 2023. Projectathons facilitate crucial development, testing and eventual deployment of national Once-Only Technical System implementations.

Neutral experts, acting as monitors, supervised and verified the tests carried out over the three days. The Once-Only Technical System Projectathons are not pass/fail type examinations. Rather, they are a collaborative exercise in understanding technical and operational issues and working together to solve them.

The June Projectathon was an excellent opportunity for national implementers to learn, help each other and to assess their current state of play regarding their Once-Only Technical System developments. In addition to testing, Member States experts collaborated on improving the Once-Only Technical System user-experience, learned about lifecycle management updates to the Once-Only Common Services, the use of eIDAS eID in realising this System, related systems and defining operational arrangements for the Once-Only domain.

The Commission will publish an event report for the June Projectathon shortly. In the meantime, you can consult the April Once-Only Technical Projectathon event report, summarising key results from the testing that cook place from 19-21 April 2023.

On the final day of this Projectathon, the ‘OOTS & EU DI Wallet Synergies and Interoperability Contact Group’ met to discuss the topic of power and mandates and data sharing in the context of cross-border identification using the European framework for digital identity (known as eIDAS).

Other Past Projectathons

Since 2023, the Commission has been organising Once-Only Technical System Projectathons. These are three-day events where national teams connect various systems and perform a marathon of peer-to-peer interoperability and compliance tests in a structured environment.

Projectathon #3

The October Projectathon is the final such event in 2023, just ahead of the legal deadline for EU Member States to implement the Once-Only Technical System. It builds on the work and experiences of the April and June Projectathons.

Projectathon #1

The April Projectathon brought together participants and observers to perform key tests on their national Once-Only Technical System implementations, ahead of the June and October sessions.
