Each year's Summit consists of a series events and continued discourse spanning three months, culminating in a free, two-day face-to-face workshop and symposium at the National Institute of Standards (NIST) in Gaithersburg, Maryland, USA.  Discussions employ email, chat and teleconferences, including presentations given by experts about issues relevant to each year’s theme. A Summit Communique, capturing the most important findings is developed throughout the summit and finalized at the symposium, endorsed by participants.
