This volume constitutes the refereed proceedings of 11 international workshops held as part of OTM 2010 in Hersonissos, Greece in October 2010. The 68 revised full papers presented were carefully reviewed and selected from a total of 127 submissions to the workshops. The volume starts with 14 poster papers of the OTM 2010 main conferences COOPIS 2010, DOA 2010 and OSBASE 2010. Topics of the workshop papers are adaption in service-oriented architectures, ambient intelligence and reasoning, data integration approaches, modeling in ADI, web and enterprise data visualization, enterprise integration and semantics, industrial enterprise interoperability and networking, process management in distributed information system development, improving social networking, ontology engineering, master data management and metamodeling, extensions to fact-oriented modeling, logic and derivation, patterns in input data models.

The two-volume set of LNCS 6426/6427 constitutes the refereed proceedings of 3 confederated international conferences on CoopIS (Cooperative Information Systems), DOA (Distributed Objects and Applications) and ODBASE (Ontologies, DataBases and Applications of SEmantics). These conferences were held in October 2009 in Greece, in Hersonissos on the island of Crete. CoopIS is covering the applications of technologies in an enterprise context as workflow systems and knowledge management. DOA is covering the relevant infrastructure-enabling technologies and finally, OSBASe is covering WEB semantics, XML databases and ontologies. The 83 revised full papers presented together with 3 keynote talks were carefully reviewed and selected from a total of 223 submissions. Corresponding to the OTM main conferences the papers are organized in topical sections on process models and management, modeling of cooperation, services computing, information processing and management, human-based cooperative systems, ontology and workflow challenges, access control, authentication and policies, secure architectures, cryptography, data storage and processing, transaction and event management, virtualization performance, risk and scalability, cloud and distributed system security, reactivity and semantic data, ontology mapping and semantic similarity, domain specific ontologies.
