Meta Abstraction Types

The different types of data that describe a service are collectively referred to as meta abstraction types. These forms of service meta data are relevant when applying the Service Abstraction design principle because their classifications help service designers determine what should and should not be made publicly available about a service.


There are four meta abstraction types:

  • Quality of Service Information
  • Technology Information
  • Functional Information
  • Programmatic Logic Information

The tendency is to regulate how much of each type should be published as part of a service contract, a service registry record, and supplementary documents, such as service level agreements.
