In this paper, we introduce an architecture description language (ADL) for PCOMs (a context oriented component model). The language is described at three levels: (1) Building blocks (PCOMs context oriented components types) (2) Connectors, which connect components externally and internally, and (3) Architectural Configuration, which includes a full description of composition and decomposition mechanisms. The contribution is designing ADL. That supports context-orinted component by providing new architecture elements, which fulfil the requirements of designing context oriented component based applications. Context oriented component is a behavioural unit composed of static parts and dynamic parts. A PCOMs component model design was introduced in our previous work. PCOMs proposes a component model design to compose context-aware system by capturing context condition at runtime. The model is a component-based one that modifies the application architecture by subdividing components into subsystems of static and dynamic elements. We map each context condition to a composable template architectural configuration. Each context condition acts to select behavioural patterns, which combine to form application architectures. Different types of architecture elements are proposed in this work. We focus in defining the following new elements: Components' dynamic and static parts, components' layers, decision policies, and composition plan. Finally we introduce an ADL that fully supports context aware applications, by supporting the definition of a component as a unit of behaviour. Our ADL clearly defines the composition mechanisms, and provides proper definition for the composition's design Patterns and composition plan. The composition plan is recursively describes the composite components, and the connection between them by describing several design Patterns. A design Pattern typically, shows the relationships and the interactions between components' dynamic behaviour part- .
