Composition of web services is much studied to support business-to-business and enterprise application integration in e-Commerce. Current web service composition approaches range from practical languages aspiring to become standards (like BPEL, WS-CDL, OWL-S and WSMO) to theoretical models (like automata, Petri nets and process algebras). In this paper we compare these approaches w.r.t. a selected set of characteristics (like trust, security and performance) and we advocate the use of formal models, and their tool support, to increase one's confidence in web service compositions. This paper can assist web service composition designers and developers to deliver lasting solutions, in concordance with the technology's critical needs.
