SOCK is a process calculus for the modeling of Service Oriented systems recently extended with primitives for dynamic fault and compensation handling. In this paper we investigate the relationships between the Sagas calculi for compensable flow composition and SOCK. First, we present an encoding of Parallel Sagas (with interruption and centralized compensation) into SOCK. Then, we discuss a new semantics for Parallel Sagas that we consider more adequate to the dynamic approach to fault and compensation handling.
