These guidelines for the archiving of academic research set out the preconditions for the archiving of data, materials and information that form the basis for publications – in other words, descriptions of data, materials and information that are needed in order to replicate research results, as well as their storage. These guidelines relate to the data, materials and information with respect to publications that appear in their definitive form as of 1 June 2018. The guidelines are based on the principle of retroactive accountability, i.e. reporting after a publication has appeared. The principle behind these guidelines is that each researcher is responsible for archiving data, materials and information, and the publications based on them, in a responsible and transparent way. In situations where this document does not provide clear-cut rules, researchers are expected to act in the spirit of these guidelines rather than observing them to the letter
