The 1st ESWC Summer School was held in Crete in May 2011, with tutors teaching topics like linked data, reasoning, and vocabulary building. Keynote speakers included experts from Oxford University, Freie Universität Berlin, IBM Research, and University of Trento. The timetable spanned Tuesday to Saturday and included tutorials, hands-on sessions, and mini-projects focused on the core concepts of linked data. The conclusions were that the summer school was a success and should be held again in 2012, co-located with ESWC, with an emphasis on fundamental linked data practices and replicating the setting in Crete.
