The recently-established NEA Working Party on Information, Data and Knowledge Management (WP‑IDKM) held its kick‑off meeting on 15‑17 January 2020. The meeting brought together 34 participants representing 26 organisations from 11 NEA member countries and the European Union (EU). The participating working group members agreed to create subsidiary ad hoc expert groups in four working areas: i) safety case, ii) knowledge management, iii) archiving, and iv) awareness preservation. These ad hoc expert groups will be launched later in 2020.
