SCA Policy Association Framework
SCA (Service Component Architecture) is a collaborative effort by the leading vendors in the enterprise software space to define an architecture for building applications and systems using a Service-Oriented Architecture. SCA allows developers to define components that implement business logic, which offer their capabilities through services and consume functions offered by other components through references in a relatively abstract manner. This paper discusses how infrastructure and Quality of Service constraints and capabilities can be associated with SCA artifacts either as abstract desires or as concrete policies.
