Simple Object Access Protocol
  • Essentially IIOP, but defined using XML to define the packet structure and HTTP as the (default) transport mechanism
    • Strongly backed by Microsoft
    • Purely a protocol specification
    • No API's are defined in the standard
      • No object adapters, and hence no standard object activation mechanism
      • No langauge mappings, so local invocation must use HTTP as well
    • A very simple object model
      • No inheritance
