A requirements pattern language for informing design

A pattern language for self aware adaptive systems is proposed as a high level systems architecture. More detailed patterns for two major components- sensing/monitoring and adapting/acting are described as architecture components. These components are set in the context of pattern languages from a separate viewpoint based on a generalisation specialisation hierarchy of abstract models for sensing and acting components. The discussion argues for pattern languages from different perspective as a means of organising the diversity of RE patterns.
