The GGF's OGSA Working Group invites you to join our webcast session, "Defining the Grid: An Introduction to the Open Grid Services Architecture," on Wednesday April 26th at 2pm EDT. In this webcast we will discuss the evolution of grid computing, explain how service-oriented grids fit with other leading-edge enterprise technologies, and describe OGSA and its core capabilities. The presentation will be given by Professor Andrew Grimshaw of the University of Virginia, a leading member of GGF and the OGSA Working Group. After the presentation Andrew and other members of the Working Group will be pleased to answer your questions. This webcast will be of interest to technology managers, architects and developers who would like to learn about standards-based grid technology and its place throughout the enterprise.
