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.

Abstract. In this paper we present first results of a SOA-based architecture framework. The architecture framework is required to be close to industry standards, especially to service component architecture (SCA), language independent (i.e. it is adoptable) and the building blocks of each system, activities and data, are first class citizens. We present a meta model of the architecture framework and discuss its concepts in detail.
