Description We present a new automata-based interface model describing the interaction behavior of software components. Contrary to earlier component- or interface-based approaches, the interface model we propose specifies all the non-blockable interaction behaviors of a component with any environment. To this end, we develop an algorithm to compute the unblockable interaction behavior, called the interface model of a component, from its execution model. Based on this model, we introduce composition operators for the components and prove important compositionality results, showing the conditions under which composition of interface models preserves unblockable sequences of provided services.
