DDI has a strong relationship to an internationally renowned informatics center in Germany, Schloss Dagstuhl – Leibniz Institute for Informatics, Wadern. Since 2007, 31 DDI expert and training workshops have been held in this extraordinary venue.
The venue and its advantages
Everything at Dagstuhl is designed to support communication between participants. The remote location encourages participants to focus on the work without interruptions, enabling intensive discussion and triggering new ideas. The seminar and break-out rooms are comfortable and conveniently located and bring people together for large and small meetings. Because participants stay for the week, they can work together through the day and continue in the evening if desired, but they can also take advantage of other social activities into the evening, such as ping-pong, billiards, or discussions in the wine cellar. Building relationships in this way results in more efficient communication and higher quality interactions overall, leading to enhanced productivity and good outcomes.
Combining training and expert workshops in sequence at the same location supports the process of building a community of qualified DDI users and specification developers. Often DDI users eventually become active contributors to further development. This is especially important for DDI as a community-driven standard. The DDI expert workshops have been supported and organized by the DDI Alliance and its members; GESIS – Leibniz Institute for the Social Sciences; the Open Data Foundation; the University of Minnesota Population Center; and CODATA (the Committee on Data of the International Science Council). Training workshops (also the two workshops on Semantic Statistics in 2011/2012) were organized by GESIS. The events have been subsidized by Dagstuhl.
Resulting public papers and specifications are listed below in connection with the related events.

DDI Moving Forward
Developing the DDI model is one of the strategic priorities of the DDI Alliance. The Alliance began work on a model-based DDI in October 2012 in a workshop at Schloss Dagstuhl and is continuing this work in subsequent workshops at the same venue and at other places. A summary describes the Moving Forward process (partly outdated). The DDI Collaboration Wiki provides all related documents.
