Abstract

Choreographic Programming is a paradigm for distributed programming, where high-level “Alice and Bob” descriptions of communications (choreographies) are used to synthesise correct-by-construction programs. However, implementations of choreographic models use message routing technologies distant from their related theoretical models (e.g., CCS/π channels). This drives implementers to mediate discrepancies with the theory through undocumented, unproven adaptations, weakening the reliability of their implementations.

As a solution, we propose the framework of Applied Choreographies (AC). In AC, programmers write choreographies in a language that follows the standard syntax and semantics of previous works. Then, choreographies are compiled to a real-world execution model for Service-Oriented Computing (SOC). To manage the complexity of this task, our compilation happens in three steps, respectively dealing with: implementing name-based communications using the concrete mechanism found in SOC, projecting a choreography to a set of processes, and translating processes to a distributed implementation in terms of services.
