Internet-based information systems, the second covering the large-scale in- gration of heterogeneous computing systems and data resources with the aim of providing a global computing space. Eachofthesefourconferencesencouragesresearcherstotreattheirrespective topics within a framework that incorporates jointly (a) theory, (b) conceptual design and development, and (c) applications, in particular case studies and industrial solutions. Following and expanding the model created in 2003, we again solicited and selected quality workshop proposals to complement the more "archival" nature of the main conferences with research results in a number of selected and more "avant-garde" areas related to the general topic of Web-based distributed c- puting. For instance, the so-called Semantic Web has given rise to several novel research areas combining linguistics, information systems technology, and ar- ?cial intelligence, such as the modeling of (legal) regulatory systems and the ubiquitous nature of their usage. We were glad to see that ten of our earlier s- cessful workshops (ADI, CAMS, EI2N, SWWS, ORM, OnToContent, MONET, SEMELS, COMBEK, IWSSA) re-appeared in 2008 with a second, third or even ?fth edition, sometimes by alliance with other newly emerging workshops, and that no fewer than three brand-new independent workshops could be selected from proposals and hosted: ISDE, ODIS and Beyond SAWSDL. Workshop - diences productively mingled with each other and with those of the main c- ferences, and there was considerable overlap in authors.
This volume constitutes the refereed proceedings of 14 international workshops held as part of OTM 2009 in Vilamoura, Portugal, in November 2009.
The 93 revised full papers presented together with 2 invited talks were carefully reviewed and selected from a total of 131 submissions to the workshops. The volume starts with 7 additional revised poster papers of the OTM 2009 main conferences DOA, IS, and ODBASE. Topics of the workshop papers are ambient data integration (ADI 2009), context-aware mobile systems (CAMS 2009), enterprise integration, interoperability and networking (EI2N 2008), information system in distributed environments (ISDE 2009), system/software architectures (IWSSA 2009), mobile and networking technologies for social applications (MONET 2009), ontology content (OnToContent 2009), ontologies in distributed and interactive systems (ODIS 2009), fact-oriented modeling (ORM 2009), OTM Academy (OTMA 2009), semantic Web and Web semantics (SWWS 2009), semantic extensions to middleware: enabling large scale knowledge (SEMELS 2009), the next steps after SAWSDL (Beyond SAWSDL 2009), and community-based evolution of knowledge-intensive systems (COMBEK 2009).
