Abstract

We develop a notion of spatial-behavioral typing suitable to discipline interactions in service-based systems modeled in a distributed object calculus. Our type structure reflects a resource aware model of behavior, where a parallel composition type operator expresses resource independence, a sequential composition type operator expresses implicit synchronization, and a modal operator expresses resource ownership. Soundness of our type system is established using a logical relations technique, building on a interpretation of types as properties expressible in a spatial logic.
