With the aim to provide a loosely-coupled, flexible as well as high-efficiency integration architecture in the deregulating and competitive electric market, the Service Oriented Architecture (SOA) is proposed. We emphasize the protocol, services, process, and event. The integration protocol stack that considers both underlying communication and content-based message exchange is discussed to realize...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
