The Dutch Knowledge Center for War Resources now has its own Open Data portal. Over the course of the last decades hundreds of organisations in Europe collected historical information on World War II. The current portal presents 59 datasets, resulting from the joint archive efforts of more than 100 organisations in the Netherlands. The Open Data registry consists of a historical thesaurus, a list of music that was forbidden during World War II, as well as Open Data on current war monuments. In this way, the Open Data portal increases the digital accessibility of war archives and teaches Dutch citizens about their country’s history.
