Data Ecosystems: Sovereign Data Exchange among Organizations (Dagstuhl Seminar 19391)

Authors: Cinzia Cappiello, Avigdor Gal, Matthias Jarke, and Jakob Rehof

Published in: Dagstuhl Reports, Volume 9, Issue 9 (2020)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 19391 ``Data Ecosystems: Sovereign Data Exchange among Organizations''. The goal of the seminar was to bring together people from different disciplines (also outside the computer science area), in order to identify (i) a set of research challenges for the future development of data ecosystems and a catalogue of major approaches relevant to the field and (ii) a set of developed use cases of particular interest to the further development of data ecosystems. Towards the objectives, the seminar included tutorials, invited talks, presentations of open problems, working groups. This report presents the most relevant findings and contributions.

Integrating Process-Oriented and Event-Based Systems (Dagstuhl Seminar 16341)

Authors: David Eyers, Avigdor Gal, Hans-Arno Jacobsen, and Matthias Weidlich

Published in: Dagstuhl Reports, Volume 6, Issue 8 (2017)

Abstract
This report documents the programme and the outcomes of Dagstuhl Seminar 16341 on "Integrating Process-Oriented and Event-Based Systems", which took place August 21--26, 2016, at Schloss Dagstuhl -- Leibniz Center for Informatics. The seminar brought together researchers and practitioners from the communities that have been established for research on process-oriented information systems on the one hand, and event-based systems on the other hand. By exploring the use of processes in event handling (from the distribution of event processing to the assessment of event data quality), the use of events in processes (from rich event semantics in processes to support for flexible BPM), and the role of events in process choreographies, the seminar identified the diverse connections between the scientific fields. This report summarises the outcomes of the seminar by reviewing the state-of-the-art and outlining research challenges on the intersection of process-oriented and event-based systems.

Authors: Karl Aberer, Avigdor Gal, Manfred Hauswirth, Kai-Uwe Sattler, and Amit P. Sheth

Published in: Dagstuhl Seminar Proceedings, Volume 10042, Semantic Challenges in Sensor Networks (2010)

Abstract
From 24.01. to 29.01.2010, the Dagstuhl Seminar 10042 ``Semantic Challenges in Sensor Networks '' was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

10042 Executive Summary – Semantic Challenges in Sensor Networks

Authors: Karl Aberer, Avigdor Gal, Manfred Hauswirth, Kai-Uwe Sattler, and Amit P. Sheth

Published in: Dagstuhl Seminar Proceedings, Volume 10042, Semantic Challenges in Sensor Networks (2010)

Abstract
There has been significant progress in the number and capabilities of mobile devices, wireless sensors, and sensor networks. These developments, combined with the improved ability to bridge between the physical and cyber world in a more seamless way, have fostered the broad availability of sensor data capturing the state of the physical world. Promising and already successful examples are applications in environmental monitoring, agriculture, surveillance and intrusion detection, public security, and supply chain management. Furthermore, ideas towards a Web of sensors have been proposed, which is to be understood as a (large scale) network of spatially distributed sensors. In particular, terms like "Internet of Things", "Collaborating Objects" and "Ambient Intelligence" emphasize the trend towards a tighter connection between the cyber space and the physical world.
