This document specifies modeling of execution environment and a basic execution service (BES) for OGSA grids.  It 
defines the proposed execution environment element and BES element for inclusion in DMTF’s Common Information Model.  
Specific execution environments, such as the OGSA BES execution environment, should be defined as profiles and/or 
extension elements of execution environment.  Operations specific to a service should not be part of the execution 
environment.
