DANS – Data Archiving and Networked Services – is an institute under the auspices of Royal Netherlands Academy of Arts and Sciences (KNAW) which is also supported by the Netherlands Organisation for Scientific Research (NWO). Since its establishment in 2005, DANS has been storing and making research data in the arts and humanities and social sciences permanently accessible. An important activity carried out by DANS is the setting up, managing and continued improvement of the user friendly archiving system EASY. In addition, DANS provides other services such as offering access to the files of large data managers, both national and international. DANS also takes part in numerous projects to make data accessible or conserves it for scientific research, among them the large-scale ESFRI-related initiative DARIAH (Digital Research Infrastructure for the Arts and Humanities), MIXED, in which a permanent format for storage and reuse of data sets is being developed and the activities around the Data Seal of Approval, which can be requested and granted to research that meets a number of clear criteria in the field of quality, permanence and accessibility of the data.
