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.Comment: IMADA-preprint-c
