In this paper we address the problem of how to extend a conventional Web service composition language with the ability to deal with data streaming services. The paper discusses several modeling alternatives and presents a marker based semantics for safely dealing with pipelined processing in service compositions. The paper also presents application examples that illustrate the advantages of the proposed approach}, keywords = {JOpera, streaming, Web service composition}, doi = {10.1109/SCC.2006.38}, author = {Bi{\"o}rn Bi{\"o}rnstad and Cesare Pautasso and Gustavo Alonso} }
