Open Grid Services Architecture

• Successful realization of the Open Grid Services
  Architecture (OGSA) vision of a broadly
  applicable and adopted framework for distributed
  system integration requires the early
  standardization of core services. The OGSA
  working group within the Global Grid Forum has
  been formed to develop a comprehensive and
  consistent OGSA roadmap that (a) defines, in
  broad but somewhat detailed terms, the scope of
  the services required to support both e-science
  and e-business applications, (b) identifies a
  core set of such services that are viewed as
  highest priority for definition, and (c)
  specifies at a high-level the functionalities
  required for these core services and the
  interrelationships among those core services
