RESUMO

Software technology is undergoing a transition from monolithic architectures, constructed according to a single overall design, into open architectures composed of conglomerates of collaborative, heterogeneous, and independently designed agents and multi-agent systems (MAS). These architectures are driven by additional system- wide properties, such as communication, coordination, adaptability, mobility and persistence. However, controlling these properties and managing different application agents is not an easy task, requiring a more sophisticated software architectural approach. In this context, we propose the Reflective Blackboard architectural pattern, which is the result of the composition of tho other well-known architectural patterns: the Blackboard pattern and the Reflection pattern. The pattern allows a better separation of concerns, supporting the separate handling of control strategies, by means of the computational reflection technique. An infrastructure, which implements the proposed pattern and provides support to multiple system-level properties, such as mobility, communication, coordination and persistence, was also developed. The Reflective Blackboard pattern was applied together with this infrastructure to the development of a Marketplace application in order to validate de concepts proposed in this work.
