Formal Modeling of Behavioral Properties to Support Correct by Design Publish/Subscribe Architectural Styles

Abstract

We propose in this paper a formal modeling approach of behavioral properties of publish/subscribe architectural styles. We extend P/S-CoM formal approach that concentrates only on correctly design the structures of publish/subscribe styles and deals with dynamic views. We put the emphasis on the state notion for component types. Moreover, we focus on behavioral properties including lossless of exchanged events, delivery semantics and ordering of notifications. These properties are coded in Z notation.
