We would like to welcome you to the proceedings of the workshops held in c- junction with the 27th International Conference on Conceptual Modeling (ER 2008). While the ER main conference covers a wide spectrum of conceptual modeling research, increasingly complex real-world problems demand new p- spectives and activeresearchin new applications.The ER workshopsattempt to provideresearchers, students, andindustry professionalswitha forumto present and discuss emerging hot topics related to conceptual modeling. We received 13 excellent proposals for workshops to be held with ER 2008. We accepted the following seven based on peer reviews: 1.
