The article shows in which areas other countries can benefit from the work of the Norwegian platform NDLA (ndla.no). This assessment is based on interviews with 13 representatives of the platform, three cooperation partners and one representative of Norwegian textbook publishers. The experiences described refer to a large-scale Open Educational Resources (OER) platform for upper secondary education, which was founded in 2006. The contents and experiences of the interviews were categorised into four areas: creation process, consumption, context based decisions and peer-production. The openness of the colleagues through the interviews conducted allows--for the first time--insights into the structures, strategies and considerations of NDLA. In conclusion, the special potential of such a state funded OER platform for inclusive education and which aspects might be relevant for higher education is shown.
