We have published a "once-only principle" article on Wikipedia in collaboration with our partner project TOOP in order to spread awareness around once-only. The article explains the once-only principle to a broader, non-expert audience and makes information around this e-government principle more easily accessible for everyone. It also highlights its importance as one of the basic principles of the EU eGovernment Action Plan 2016-2020. 

Currently, the article focuses on national and cross-border implementations of the once-only principle while also introducing the two once-only projects, TOOP and SCOOP4C. There are also sections discussing the benefits, barriers, criticism and public reception of the principle. 

We would like to encourage you to please contribute to this article by adding information you think is missing or translating the article into your mother tongue so that it can reach more people.
