Process-aware web programming with Jolie

We extend the Jolie programming language to capture the native modelling of process-aware web information systems, i.e., web information systems based upon the execution of business processes. Our main contribution is to offer a unifying approach for the programming of distributed architectures on the web, which can capture web servers, stateful process execution, and the composition of services via mediation. We discuss applications of this approach through a series of examples that cover, e.g., static content serving, multiparty sessions, and the evolution of web systems. Finally, we present a performance evaluation that includes a comparison of Jolie-based web systems to other frameworks and a measurement of its scalability. •A framework, based on the Jolie programming language, for the native modelling of process-aware web information systems.•The framework unifies the programming of web servers, sessions, and service mediators in the web.•Application examples demonstrating the suitability of the approach for composing complex and evolving web systems.•A performance evaluation of the proposed approach.
