We present the design of a BPEL orchestration engine based on ReSpecT tuple centres, a coordination model extending Linda with the ability of declaratively programming the reactive behaviour of tuple spaces. Architectural and linguistic aspects of our solution are discussed, focussing on how the syntax and semantics of BPEL have been mapped to tuple centres. This is achieved by a translation of BPEL specifications to set of logic tuples, and conceiving the execution cycle of the orchestration engine in terms of ReSpecT reactions.
