The working groups 3 (IDS Clearing Committee) and 4 (Extraction software for IDS) held a workshop in Umeå. The most important aim of the workshop was to come to an agreement on how to move forward. Based on the discussions, we made a schedule for creating important extraction programs, that will be the core of the extraction software. Each partner in the workgroup was given assignments and there were suggestions on what important topics need to be raised during the next EHPS-net meeting in September in Budapest.
