Current and future software needs remain focused towards the development of large and complex Intelligent Networked Information Systems, covering a wide range of issues. These include Data and Web Semantics, Distributed Objects, Web Services, Grid Computing, High-performance and Distributed Applications, Databases, Workflow, Cooperation, Interoperability, and Mobility as required for the deployment of Internet- and Intranet-based systems in organizations and for e-business. This federated event is unique at providing an opportunity for both researchers and practitioners to meet and understand recent developments in ubiquitous computing, interacting with colleagues in adjoining related fields.

OnTheMove (OTM) while existing since 2002 now for the first time returns to the North American continent co-locating five successful related and complementary conferences: DOA = infrastructure, ODBASE = meaning of data, CoopIS = application in organizations, GADA = grid computing, high-performance and distributed applications, IS = information security. Each conference covers multiple research vectors, viz. theory (e.g. underlying formalisms), conceptual (e.g. technical designs and conceptual solutions) and applications (e.g. case studies and industrial best practices).

All five conferences share the scientific study of the distributed, conceptual and ubiquitous aspects of modern computing systems, and share the resulting application-pull created by the WWW. For DOA'08, the primary emphasis will be on the distributed objects underlying the required archtitectures; ODBASE'08 concentrates on the knowledge bases and methods required for enabling semantical use; CoopIS'08 will report on the state of the art on interaction of such technology and methods within an enterprise or networked organization; and for GADA'08, the focus is on the integration of heterogeneous computing systems and data resources with the aim of providing a global computing space.

As they must, these subject areas overlap in interesting ways and, in fact the organizers specifically welcome submissions in any of the areas that also emphasize the envisaged impact on or from relevant issues in the others. To stimulate this "cross-pollination", we offer a shared program of famous and representative keynote speakers, as well as a parallel program consisting of a number of highly topical workshops covering emerging related areas.
