<p id="_ef7c8eaa-f6e0-f4ae-2e82-fbd34726da15">Roundtable XXV took place on October 3-5, 2012, hosted by Google in Zürich, Switzerland. The event was attended by 26 people from 11 members and 5 non-members. The CalConnect Interoperability Test Event was held immediately prior to the Roundtable on October 1-3. Twenty-two people from 10 members and 2 non-members were present onsite, and four members participated remotely.</p>

<p id="_18c8a8ac-1e42-2564-35a6-669eaeafd339">The Roundtable was dedicated to technical committee sessions, and informal discussions and networking, with an all-hands Plenary meeting as the last item on Friday afternoon. The Technical Committee sessions were as usual organized sequentially, without competing parallel sessions, as is our standard practice to allow all attendees who wished to be involved in the discussions of each Technical Committee the opportunity to do so.</p>
