This book is focused on an emerging area, i.e. combination of IoT and semantic technologies, which should enable breaking the silos of local and/or domain-specific IoT deployments. Taking into account the way that IoT ecosystems are realized, several challenges can be identified. Among them of definite importance are (this list is, obviously, not exhaustive): (i) How to provide common representation and/or shared understanding of data that will enable analysis across (systematically growing) ecosystems? (ii) How to build ecosystems based on data flows? (iii) How to track data provenance? (iv) How to ensure/manage trust? (v) How to search for things/data within ecosystems? (vi) How to store data and assure its quality? Semantic technologies are often considered among the possible ways of addressing these (and other, related) questions. More precisely, in academic research and in industrial practice, semantic technologies materialize in the following contexts (this list is, also, not exhaustive, but indicates the breadth of scope of semantic technology usability): (i) representation of artefacts in IoT ecosystems and IoT networks, (ii) providing interoperability between heterogeneous IoT artefacts, (ii) representation of provenance information, enabling provenance tracking, trust establishment, and quality assessment, (iv) semantic search, enabling flexible access to data originating in different places across the ecosystem, (v) flexible storage of heterogeneous data. Finally, Semantic Web, Web of Things, and Linked Open Data are architectural paradigms, with which the aforementioned solutions are to be integrated, to provide production-ready deployments.

This book constitutes the refereed proceedings of the 7th International Workshop on Databases in Networked Information Systems, DNIS 2011, held in Aizu-Wakamatsu, Japan in December 2011. The 18 revised full papers presented together with 6 invited talks and 1 keynote lecture were carefully reviewed and selected for inclusion in the book. The workshop generally puts the main focus on data semantics and infrastructure for information management and interchange. The papers are organized in topical sections on cloud computing; access to information resources; information and knowledge management; bio-medical information management; information extraction from data resources; geo-spatial decision making; networked information systems: infrastructure.

Large-scale information systems in public utility services depend on computing infrastructure. Many research e?orts are being made in related areas, such as mobile computing, cloud computing, sensor networks, high-level user interfaces and information accesses by Web users. Government agencies in many countries plan to launch facilities in education, health-care and information support as a part of e-government initiative. In this context, information interchange m- agement has become an active research ?eld. A number of new opportunities have evolved in design and modeling based on the new computing needs of the users. Database systems play a centralrole in supporting networkedinformation systems for access and storage management aspects. The 6thinternationalworkshoponDatabasesin NetworkedInformationS- tems (DNIS) 2010 was held during March 29-31, 2010 at University of Aizu in Japan. The workshop program included research contributions and invited c- tributions. A view of research activity in information interchange management and related research issues was provided by the sessions on related topics. The keynoteaddresswascontributedbyDivyakantAgrawal. Theworkshopsessionon "NetworkedInformationSystems:Infrastructure"had invitedpapersbyHarumi KunoandMaluCastellanos. Thesessionon"AccessestoInformationResources" had an invited contribution from Joachim Biskup. The following section on "Information and Knowledge Management Systems" included invited contri- tions from Toyoaki Nishida and Tetsuo Kinoshita.

The section on "Geospatial Decision Making" comprised c- tributions by Cyrus Shahabi and Yoshiharu Ishikawa. We would like to thank the members of the Program Committee for their support and all authors who contributed to DNIS 2010.

This book constitutes the refereed proceedings of the 5th International Workshop on Databases in Networked Information Systems, DNIS 2007, held in Aizu-Wakamatsu, Japan in October 2007.

Information systems in healthcare and public utility services depend on comp- ing infrastructures. Many research e?orts are being made in related areas, such as wireless computing (e. g. , Auto-ID Laboratories, and projects at MIT), W- based computing, and information accesses by Web users. Government agencies in many countries plan to launch facilities in education, healthcare and infor- tion support as a part of e-government initiatives. In this context, information interchange management has become an active research ?eld. A number of new opportunities have evolved in design and modeling based on new computing needs of users. Database systems play a central role in supporting networked information systems for access and storage management aspects. The4thInternationalWorkshoponDatabasesinNetworkedInformationS- tems (DNIS 2005) was held on March 28-30, 2005 at the University of Aizu in Japan.
