At the upcoming Global Grid Forum meeting in Berlin there will be a one day session on web service workflow for grids. Workflow is a critical part of the emerging Grid Computing Environments and captures the linkage of constituent services together to build larger composite services. Workflow encompasses a broad range of approaches with names like "Service Orchestration", "Application Integration", or "Software Bus". When web service workflow technologies are linked with networks, sensors, instruments and software processes it creates exciting new opportunities to create grids "on the fly" or "real time" grids to link sensors and instruments with databases and computation facilities. It opens up new opportunities for grids and web services in areas such as process control, remote instrumentation, network management, etc. The CANARIE User Controlled LightPath (UCLP) technology is an early prototype of such an architecture where end users can link together devices such as network elements which are exposed as web services to create new network topologies and services for optimized for specific grid applications in high energy physics, oceanography, bio-informatics, etc. Global Grid Forum 10, Berlin, Germany, March 9-12, 2004 www.globalgridforum.org/Meetings/ggf10/reg.htm Full Registration is Available though 5-March All Sessions held at Humboldt University in downtown Berlin Plenary Program Keynotes include: "OGSI Evolution" by Steve Tuecke, Argonne National Laboratory A Special Address by the German Minister for Science and Education Four Full-Day Workshops: The Future of Grid Data Environments - Organizers: Malcolm Atkinson, Ann Chervenak, Andrew Merzky & Susan Malaika Workflow in Grid Systems - Organizers: Dennis Gannon, Geoffrey Fox, Abbas Farazdel, Carole Goble, Ewa Deelman, Dave Berry Grid Services for Particle and Nuclear Physics Applications - Experience and Requirements Workshop, Organizers: Ian Bird, Doug Olson, Ruth Pordes Case Studies on Grid Applications - Organizer: Tom Hinke
