Service Reference Model - also known as a Service Component Reference Model -- a business and performance-driven, functional framework that classifies Service Components with respect to how they support business and/or performance objectives; structured across horizontal and vertical service domains that, independent of the business functions, can provide a leverage-able foundation to support the reuse of applications, application capabilities, components, and business services.
