Object Orientation and Web Services

The annual European workshop on Object Orientation and Web Services focusses challenges and potentials of service-oriented computing in relation to object-oriented technologies and methodologies. In particular it brings together the academic and the industrial perspective on Web Services. This year’s issue was characterised by the competency and motivation of the participants, both workshop activists who presented their specific results as well as organisers and invited speaker, who contributed their broad experience. This report outlines the contributions and discussions of the event, as well as the conclusions reached by the participants. 1 Structure of the Workshop The second annual European workshop on Object Orientation and Web Services (EOOWS’04) brought together researchers and practitioners interested in the relation of service-orientedand object-oriented computing paradigms (section 2). With this year’s event, EOOWS entered its second round since initiation at ECOOP 2003 in Darmstadt and proved its role as a constant workshop series. The workshop was lead by Giacomo Piccinelli and Winfried Lamersdorf, who compiled an attractive mix that included general perspectives of an invited talk, a brought variety of specific contributions and lively discussions spanning the whole event. Around fifteen people where participating, including presenting and non-presenting attendees. Initially, the invited talk added an interdisciplinary perspective to the workshop and extended the discussions beyond usual Web Service scenarios. The talk was given by Daragh Byrne from the Edinburgh Parallel Computing Center (EPCC) [1]. Daragh Byrne works at EPCC as an Applications Consultant. At the time of this writing, he is engaged in the OGSA-DAI project, which involves generalizing data access for the Grid. The talk provided an architectural blueprint of Grid systems with special focus on the Open Grid Service ArchitecThe title of this report should be referenced as “Report from the ECOOP 2004 Workshop on Object Orientation and Web Services”.
