Open Plaques http://openplaques.org/ is an open source project that is collecting and collating information about commemorative plaques around the world. The resulting geographical data is available licence-free for projects to use.
We’ll be holding our Open Plaques Open Day event on Saturday 25th September 2010 in the Centre for Creative Collaboration (venue hashtag: #c4cc). If you’re interested in joining us, save the date! Located centrally just 5 minutes walk from Kings Cross station.
