Wilson Abstract: This document specifies a Service Discovery API extension to the Simple API for Grid Applications (SAGA), a high level, application-oriented API for grid application development. This Service Discovery API is motivated by a number of Use Cases collected by the OGF SAGA Research Group in GFD.70, and by requirements derived from these Use Cases, as specified in GFD.71. It allows users to find services with minimal prior knowledge of the grid or grids they plan to use. -- Greg Newby, OGF Editor
