	Preliminary Program (in PDF) Proceedings Editorial (in PDF) Keynote Abstract (in PDF) Workshop Program 08:30-09:00 Breakfast 09:00-10:30 Session 1 - Welcome by Vladimir Tosic - Keynote “Privacy Issues in Middleware for Service-oriented Applications” by Patrick C.K. Hung - “Network-Centric Middleware for Service Oriented Architectures across Heterogeneous Embedded Systems” by Andreas Wolff, Stefan Michaelis, Jens Schmutzler and Christian Wietfeld (presentation of a short paper) - “Web Services Interfaces and Open Standards Integration into the European UNICORE 6 Grid Middleware” by Morris Riedel et al. (presentation of a short paper) 10:30-11:00 Morning coffee 11:00-12:30 Session 2 - Open forum "Impact of Various Execution Environments on Middleware for Web Services" moderated by Vladimir Tosic The use of Web service requesters and providers executing in diverse executing environments is increasing rapidly. On one side of the spectrum are mobile and/or embedded environments, somewhere in the middle are the traditional business server environments, while on the other end of the spectrum are Grid computing systems. Embedded environments and many mobile environments are characterized with limited resources, such as processing power, memory, communication bandwidth, electrical energy. Mobility brings a number of issues and opportunities, such as location updates and contextawareness. Among the issues with increased importance for Web services in executing Grid systems are virtualization and instance lifecycle management. Due to these and other issues, middleware for Web services executing in one type of execution environment might require significant modifications to accommodate other execution environments. While many MWS 2007 workshop participants already gained significant experience about these issues, their impact, and possible solutions (as well as non-solutions), there are still many unknowns. Thus, the goal of this discussion session is to facilitate exchange of knowledge, experiences, ideas, and opinions in this important area. Participants who wish to present a position statement (5-10 minutes) on this topic should contact the moderator (via e-mail vladat at server: computer.org).  12:30-14:00 Lunch 14:00-15:30 Session 3 - “BFT-WS: A Byzantine Fault Tolerance Framework for Web Services” by Wenbing Zhao (presentation of a full paper) - winner of the “Most Promising Research” paper award sponsored by NICTA (http://nicta.com.au) - “Usage Tracking Components for Service-Oriented Middleware Systems” by Daniel Skrobo, Klemo Vladimir and Sinisa Srbljic (presentation of a full paper) - “An Economy Driven Resource Allocation Middleware for Grid Workflow” by Pengcheng Xiong and Yushun Fan (presentation of a full paper) 15:30-16:00 Afternoon coffee 16:00-17:30 Session 4 - “Alignment of Authentication Information for Federation” by Zhengping Wu and Alfred C. Weaver (presentation of a full paper) - “Towards a Privacy Policy Enforcement Middleware with Location Intelligence” by Yi Zheng, Dickson K.W. Chiu, Hongbing Wang and Patrick C.K. Hung (presentation of a full paper) - “Metadata Support for Transactional Web Services” by Maciej P. Machulak, Jonathan J. Halliday and Mark C. Little (presentation of a short paper) - Announcement of the “Most Promising Research Award” sponsored by NICTA - Final comments by Vladimir Tosic and other participants Back to the top About the Workshop During the past several years, Web services technologies have become very prominent in both the research community and the industry. Web services are distributed computing application components that use a number of Extensible Markup Language (XML) based technologies to implement the service-oriented architecture (SOA). Implementation-independence of Web services technologies allows different businesses to collaborate and achieve common business goals despite the fact that the collaborating Web services can be distributed over the Internet, run on different platforms, and implemented in different programming languages. Web services technologies are already embedded in various products and services of all major computing companies and used for diverse purposes. An important application area is e-business process integration in business-to-business (B2B) and/or enterprise application integration (EAI) scenarios. Additionally, Web service technologies became the basis for several other recent distributed computing technologies, such as Grid services and Semantic Web services. Middleware plays an important role for Web services technologies. Reusable Web services technologies are implemented in middleware, so appropriate middleware is a prerequisite for the growing acceptance of these technologies. For example, implementation independence of Web services is achieved using middleware, such as application servers and/or SOAP engines (software that analyzes, processes, and generates SOAP messages). In addition, middleware solutions have been proposed to provide, monitor, and manage quality of service (QoS) aspects, such as response time, throughput, availability, reliability, security, and privacy. The goal of this workshop is to bring together industrial, academic, and government researchers and developers interested in Web services and/or middleware technologies. Through paper presentations and discussions, this workshop will contribute to the exchange of knowledge and ideas, dissemination of results about completed and on-going research projects, as well as identification and analysis of remaining open research issues.  Middleware is traditionally one of the main topics in the EDOC (Enterprise Distributed Object Computing) community, while Web services are quickly becoming a key technology within enterprise computing and thus also one of the central topics of EDOC conferences. Therefore, we have organized the Middleware for Web Services (MWS) 2005 workshop at EDOC 2005 and the Middleware for Web Services (MWS) 2006 workshop at EDOC 2006. The workshops were successful, as they gathered academic, industrial, and government researchers and developers interested in Web services and/or middleware technology, many of whom have not attended previous EDOC conferences. Several regular EDOC attendees, some of whom have extensive experience with middleware for other distributed computing technologies, but not yet Web services, also attended the workshop. The keynote speakers (Dr. Heiko Ludwig from IBM Research at MWS 2005 and Professor Lionel M. Ni from Hong Kong University of Science and Technology at MWS 2006) and the panelists were praised for the insights they passed to the audience. This all lead to useful exchanges of ideas, improvement of understanding of wider research issues, and clearer identification of important open research issues and possible approaches towards their solution. Another successful recent workshop in this area was Middleware for Service Oriented Computing (MW4SOC) 2006 held at Middleware 2006. While MWS 2006 and MW4SOC 2006 were organized by separate groups of researchers, we have now established close collaboration and coordination. To further the achievements of MWS 2005, MWS 2006, and MW4SOC 2006 and to facilitate scientific growth of this important area, we now organize the Middleware for Web Services (MWS) 2007 workshop at EDOC 2007. The Middleware for Service Oriented Computing (MW4SOC) 2007 held at Middleware 2007 is also forthcoming.  Papers presenting and analyzing completed projects are particularly welcome. Papers about on-going research projects are also welcome, especially if they contain critical analysis of already achieved results and remaining open research issues. In addition, we invite papers about experiences and comparative analysis of middleware-related issues for Web services. We especially encourage submissions from industry. While the focus of the workshop is middleware for Web services, we are also interested in papers discussing the use of Web services as a middleware technology for utility computing, telecommunications, e-business, e-government, peer-to-peer (P2P) systems, distributed artificial intelligence, spontaneous networks, and other application areas.  Back to the top Topics of Interest (include, but are not limited to)
