Submissions are expected in the following categories: * regular papers (11 to 15 pages) * short papers (up to 8 pages) * lightning talks (extended abstracts) Submissions can use LNCS or EC-EASST style, but accepted papers will have to be (re-)formatted for EC-EASST style before the camera-ready deadline. Regarding the EC-EASST style, note that the cover page automatically produced does not count towards the page limits. Submission will be electronically at https://www.easychair.org/conferences/?conf=bx2012.
