      ABSTRACT = {Multiple architectural views of a system are often helpful in describing a system's design. While there are numerous languages for describing the contents of an individual architectural view, to date those languages have not supported the description of relationships between views. In this report we describe an extension to Acme for expressing maps between the structural aspects of architecture and for expressing constraints over those maps. },
