Blockchain Technology for Collaborative Information Systems (Dagstuhl Seminar 18332)

Authors: Marlon Dumas, Richard Hull, Jan Mendling, and Ingo Weber

Published in: Dagstuhl Reports, Volume 8, Issue 8 (2019)

Abstract
Blockchain technology enables an evolving set of parties to maintain a safe, permanent, and tamper-proof ledger of transactions without a central authority. This technology opens manifold opportunities to redesign business-to-business collaborations, while bringing about numerous challenges. These opportunities and challenges were discussed in the Dagstuhl Seminar 18332 "Blockchain Technology for Collaborative Information Systems". This report documents the program and the outcomes of the seminar.

Research Directions for Principles of Data Management (Dagstuhl Perspectives Workshop 16151)

Authors: Serge Abiteboul, Marcelo Arenas, Pablo Barceló, Meghyn Bienvenu, Diego Calvanese, Claire David, Richard Hull, Eyke Hüllermeier, Benny Kimelfeld, Leonid Libkin, Wim Martens, Tova Milo, Filip Murlak, Frank Neven, Magdalena Ortiz, Thomas Schwentick, Julia Stoyanovich, Jianwen Su, Dan Suciu, Victor Vianu, and Ke Yi

Abstract
The area of Principles of Data Management (PDM) has made crucial contributions to the development of formal frameworks for understanding and managing data and knowledge. This work has involved a rich cross-fertilization between PDM and other disciplines in mathematics and computer science, including logic, complexity theory, and knowledge representation. We anticipate on-going expansion of PDM research as the technology and applications involving data management continue to grow and evolve. In particular, the lifecycle of Big Data Analytics raises a wealth of challenge areas that PDM can help with. In this report we identify some of the most important research directions where the PDM community has the potential to make significant contributions. This is done from three perspectives: potential practical relevance, results already obtained, and research questions that appear surmountable in the short and medium term.

Fresh Approaches to Business Process Modeling (Dagstuhl Seminar 16191)

Authors: Richard Hull, Agnes Koschmider, Hajo A. Reijers, and William Wong

Published in: Dagstuhl Reports, Volume 6, Issue 5 (2016)

Abstract
Business Process Management (BPM) has significantly advanced and gained high popularity in industry. However, it remains an open issue why tools frequently are used for business process modeling that are not mainly implemented for this purpose. Often, macros for Microsoft Visio or Microsoft Excel form the first choice to capture the flow of business activities. One reason why these tools might be used is the low training effort and the fast creation of a quick model, which can be generated with these tools. Another reason for the “lower” preference of BPM software tools might be their inability to respond to changes in technology and working styles, e.g. the shift towards "agile" processes and the "flattening" of workforce hierarchies that bring more stakeholders into contact with a much broader array of processing steps than before. A central question is whether the BPM community should create an entirely new paradigm for process modeling. One can think of more intuitive drawing conventions that laymen would use, and of models of an entirely different kind (i.e. not process-centric and not data- or case-centric) that still bear the possibility to support modern and future business process. The purpose of this seminar was to bring together a cross-disciplinary group of academic and industrial researchers to foster a better understanding of how to ease the access to, and applicability of, business process modeling. We discussed business process modeling approaches against emerging trends such as Internet of Things, the need for incremental and agile creation of new processes, and the need for workers to understand and participate in multiple contextual levels (e.g. transactional, business goals, strategic directions) while performing processes. The seminar also considered how new technologies, such as modern tools for UI design (e.g. D3, node.js) could be applied to support fundamentally shifts in how processes are modeled and how humans are involved with their execution.

Foundations of Data Management (Dagstuhl Perspectives Workshop 16151)

Authors: Marcelo Arenas, Richard Hull, Wim Marten, Tova Milo, and Thomas Schwentick

Published in: Dagstuhl Reports, Volume 6, Issue 4 (2016)

Abstract
In this Workshop we have explored the degree to which principled foundations are crucial to the long-term success and effectiveness of the new generation of data management paradigms and applications, and investigated what forms of research need to be pursued to develop and advance these foundations. The workshop brought together specialists from the existing database theory community, and from adjoining areas, particularly from various subdisciplines within the Big Data community, to understand the challenge areas that might be resolved through principled foundations and mathematical theory.

07051 Executive Summary – Programming Paradigms for the Web: Web Programming and Web Services

Authors: Richard Hull, Peter Thiemann, and Philip Wadler

Published in: Dagstuhl Seminar Proceedings, Volume 7051, Programming Paradigms for the Web: Web Programming and Web Services (2007)

Abstract
The world-wide web raises a variety of new programming challenges. To name a few: programming at the level of the web browser, data-centric approaches, and attempts to automatically discover and compose web services. This seminar brought together researchers from the web programming and web services communities and strove to engage them in communication with each other. The seminar was held in an unusual style, in a mixture of short presentations and in-depth discussion sessions in small groups. This style enabled the participants to identify and discuss burning questions in small birds-of-a-feather sessions as well as in large plenary sessions. It required active participation of all attendees.
