The event was organised by the University of Finland (UEF, http://www.uef.fi/) and the Digitarium, (http://digitarium.fi/en) - EU BON consortium member and WP2 Leader, in collaboration with CETAF ISTC and other EU BON work packages. It aimed to demonstrate the new EU BON developments and prototypes, try out new ideas and share experience between partners. The main outcomes of the meeting are draft documents on information architecture (more particularly registry and portal) and data sharing tools and action plans for the next year. 36 people from the EU BON consortium and beyond (16 countries) attended the workshop (see participant list in the Annex).
