Architecture Description Language (ADL) is one of the keys to software architecture research, but most attention was paid to the description of software structure and high-level analysis of some system properties, while the ability to support refinement and implementation of Software Architecture (SA) models was ignored. In this paper, we present the ABC/ADL, an ADL supporting component composition. Besides the capability of architecting software systems, it provides support to the automated application generation based on SA model via mapping rules and customizable connectors.
