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. The Second International Workshop on Conceptual Modeling for Life S- ences Applications (CMLSA 2008), organized by Yi-Ping Phoebe Chen and Sven Hartmann. 2. The 5th International Workshopon Evolution and Change in Data Mana- ment (ECDM 2008), organized by Fabio Grandi. 3. The 4th International Workshop on Foundations and Practices of UML (FP-UML 2008), organized by Juan Trujillo and Andreas L. Opdahl. 4. The First International Workshop on Modeling Mobile Applications and Services (M2AS 2008), organized by Fernando Ferri, Patrizia Grifoni, and Maria Chiara Caschera. 5. The Second International Workshop on Requirements, Intentions and Goals in Conceptual Modeling (RIGiM 2008), organized by Colette Rolland, C- son Woo, and Camille Salinesi. 6. The Second International Workshop on Semantic and Conceptual Issues in Geographic Information Systems (SeCoGIS 2008), organized by Esteban Zim anyi and Christophe Claramunt. 7. The 5th International Workshop on Web Information Systems Modeling (WISM 2008), organized by Flavius Frasincar, Geert-Jan Houben, and Philippe Thiran."

We would like to welcome you to the proceedings of the workshops held in conjunction with the 23rd International Conference on Conceptual Modeling (ER 2004). The objective of the workshops associated with ER 2004 was to give p- ticipants the opportunity to present and discuss emerging hot topics related to conceptual modeling, thereby adding new perspectives to conceptual mod- ing. To meet the objective, we selected six workshops with topics on conceptual modelingforWebinformationintegration, digitalgovernment, GIS, changem- agement, e-business, and agent technology. Some of these workshopswere brand new while others had been held in conjunction with ER conferences as many as ?ve times. They are: 1. 1stInternationalWorkshoponConceptualModel-DirectedWebInformation Integration and Mining (CoMWIM 2004) 2. 1st International Workshop on Digital Government: Systems and Techno- gies (DGOV 2004) 3. 1st International Workshop on Conceptual Modeling for GIS (CoMoGIS 2004) 4. 3rd International Workshop on Evolution and Change in Data Management (ECDM 2004) 5. 1st International Workshop on Conceptual Modelling for Agents (CoMoA 2004) 6. 5th International Workshop on Conceptual Modeling Approaches for E-Business (The Model-Driven Design Value Proposition) (eCOMO 2004) These six workshops received 38, 16, 58, 21, 17, and 13 papers, respectively. Following the philosophy of the ER workshops, the selection of contributions was very carefully carried out in order to keep the excellent standard; 13, 6, 16, 8, 7, and 6 papers were accepted by the six workshops, respectively, with acceptance rates 34%, 37%, 27%, 38%, 41%, and 46%, respective
