Over the years, Wikipedia has earned its position to be one of the best information sources available online. Thanks to combined efforts of TOOP & SCOOP4C teams, the article about Once-Only Principle has been published there. It explains in detail, what precisely this Principle is about.
Apart from the explanation of the OOP, readers are able to expand their knowledge with the examples of implementation on national and cross-border scale. Topics like benefits, barriers, criticism and public reception of the OOP are also presented in the article. TOOP and SCOOP4C are mentioned as well, as the projects working towards the implementation of the Once-Only Principle in Europe.
