Global Protocol Implementations via Attribute-Based Communication

Several type systems have been developed to address the conformance between specifications and implementations, where types are specifications and type-checking ensures the conformance relation. In this paper, we take a different perspective and assume that programming takes place only at the specification level, by using a type language that captures protocols of interaction. Specifications provide the global interaction scheme and lay the basis for an automatic provably correct generation of implementations. The latter is obtained by a translation into a rich formalism that relies on attribute-based communication, whose expressiveness permits modeling in a natural way the symmetric link between message recipient and emitter.
