This volume consists of the proceedings of the 1st International Conference on Grid Services Engineering and Management (GSEM 2004)that washeld in c- junction with the 5th International Conference Net.ObjectDays 2004 (NODE 2004) and the European Conference on Web Services 2004 (ECOWS 2004) in Erfurt, Germany on 27-30 September 2004. The Grid has emerged as a global platform to support on-demand virtual organizations for coordinated sharing of distributed data, applications and p- cesses. Service orientation of the Grid also makes it a promising platform for seamlessanddynamicdevelopment, integrationanddeploymentofservice-ori- ted applications. The application components can be discovered, composed and delivered within a Grid of services, which are loosely coupled to create dynamic business processes and agile applications spanning organizations and comp- ing platforms. The technologies contributing to such grids of services include Web services, the semantic Web, grid computing, component softwareand agent technologies. The GSEM 2004 conference provided an international forum for presenting thelatesttheoreticalandpracticalresultsintechnologysolutionsforengineering and management of Grid services and service-oriented applications. The conf- ence aimed at bringing together researchersand practitioners from diverse ?elds and interests, including Web services, the semantic Web, Grid infrastructures, software components, work?ows, agent technologies and service management, and those looking for new business and research cooperation opportunities in the area of Grid services and service-oriented application

After some time of early experience Web Services are moving themselves from a new highly fragmented technology to a piece of nowadays infrastructures which promise to address various current challenges. These include especially classical issues of integration and data in a heterogeneous environment. The Web Service technology provides an open and technology-agnostic interface, and furthermore propels new usage paradigms in distributed computing infrastructures like Grid Services. Successful adoption of Web Service technology relies on the de?nition of interoperable architectural building blocks which can be integrated in existing softwarearchitectures, likeJ2EEorCORBAheritage. Interoperabilitywillsurely proveitselfasthecriticalsuccessfactoroftheWebServiceproliferation. Inorder to accomplish these interoperability various standardization bodies such as the W3C, UN or OASIS founded activities to create speci?cations and products implementing these building blocks. As the sister event of the First International Conference on Web Services (ICWS 2003), which was held in Las Vegas, June 23 - 26, USA, has proven to be an excellent catalyst for research and collaboration, the 2003 International C- ference on Web Services - Europe (ICWS-Europe 2003) is expected to continue this trend. The topics of papers collected in this proceedings volume ranges from issues like modeling, development, deployment, publishing, as well as discovery, composition and collaboration, plus monitoring and analytical control. Addit- nal contributions summarize some research and development challenges of bu- ding Web Service solutions. Especially, some contributions present an emerging research direction, namely, Web Services collaboration. Moreover, some major research activities associated with facilitating extended business collaboration using Web services and semantic annotation are also covered

  This book constitutes the thoroughly refereed post-proceedings of the Web- and Database-Related Workshops held during the NetObjectDays international conference NODe 2002, in Erfurt, Germany, in October 2002. The 19 revised full papers presented together with 3 keynote papers were carefully selected during 2 rounds of reviewing and improvement. The papers are organized in topical sections on advanced Web-services, UDDI extensions, description and classification of Web services, applications based on Web-services, indexing and accessing, Web and XML databases, mobile devices and the Internet, and XML query languages.
