quality of service meta data (abstraction type)

Any information pertaining to a service's runtime behavior, performance or reliability requirements, or other QoS details are represented by the quality of service meta data type.

When building services as Web services, this type of information is most commonly associated with WS-Policy assertions and service level agreements (SLAs).

Some level of quality of service information is often made publicly available so that service consumer designers are aware of the service's needs as well as behavioral characteristics that the consumer programs can be designed to accommodate (for example, a regular outage period).


This is one of four abstraction meta types. The other three types are:

  • Technology Information
  • Functional Information
  • Programmatic Logic Information
