As this 'open data' community starts building, there are going to be a number of meetings that would be appropriate to advertise.
For instance, the May 16-17th meeting at the National Academies that's open to the public (although the registration deadline was a few days ago):
- Public Access to Federally-Supported Research and Development Data and Publications: Two Planning Meetings
Or the session proposals for the Fall AGU go through. (sorry, can't direct link because the ScholarOne abstract system that they use just plain sucks)**
... I'm debating if it's worth listing the invitation-only meetings, such as the OSTP Big Data Senior Steering Group meeting at the end of the month. (maybe so people know to look for reports after the fact? have to balance that against people bugging the organizers to try to get an invitation ... like I managed to pull off for BRDI's meeting on Data Attribution & Citation.)
** Disclaimer : I'm the submitter of the two proposals, one invitation-only Union, one open in Public Affairs; and I'm also the person who was circulating the petition to free the AGU session data at the 2011 meeting, so I have a recorded bias against ScholarOne (in part because I can share a direct link to a session I propose, so people can easily submit to it!)
