[en] In previous newsletters we have focussed on some aspects of the Section's work such as EXFOR or Atomic and Molecular data. In the current one there are details of the work of the Nuclear Data Development Unit. A major event in the last six months has been the Nuclear Data for Science and Technology ND2013 Conference held in New York, USA. High attendance and high quality of papers indicate the continuing interest in nuclear data worldwide. An area of current discussion is new representations of the familiar data formats established for all data files, evaluated reaction data, experimental reaction data and evaluated structure data. One possibility is the use of XML and this is being discussed in various international fora. Feedback from readers on this topic is very much welcomed
