Using an Architecture Description Language to Model a Large-Scale Information System -- An Industrial Experience Report

An organisation that had developed a large Information System wanted to embark on a programme of significant evolution for the system. As a precursor to this, it was decided to create a comprehensive architectural description. This undertaking faced a number of challenges, including a low general awareness of software modelling and software architecture practices. The approach taken for this project included the definition of a simple, specific, architecture description language. This paper describes the experiences of the project and the ADL created as part of it.
