The submission deadline for research contributions is April 13th, 2015 AoE (March 29th, 2015). Please see the OpenSym 2015 call for submissions (papers) for more information. Please also note that due to the timing (various holidays) we do not expect to grant an extension to this deadline. Use the button on the right for direct access to submitting your papers through EasyChair (or use the link)! Doctoral symposium submissions and industry and practitioner submissions have a bit more time.
