Welcome to ETheCoM 2009 !
The ETheCoM 2009 workshop is held in conjunction with the 28th International Conference on Conceptual Modeling (ER 2009) in Gramado, Brazil.
The ETheCoM workshop tries to bring together researchers with an interest in theoretical foundations of conceptual modelling. The emphasis is on evolving theories that address mathematical and logical underpinnings of new developments in conceptual modelling, e.g. addressing service-oriented software systems, personalisation of Information Systems and services, network-centric and web-based applications, biomedical applications, games and entertainment, etc. We are interested in precisely worked-out semantics, in particular with respect to constraints, and in the usage of such semantics for the reasoning and inferencing about model properties.
