 The remainder of the paper is structured as follows: Section 2, presents our system model, illustrating a reference scenario where data is owned by multiple organizations. Section \ref{sec:template} introduces the pipeline template and describe data protection and functional annotations. Section \ref{sec:instance} describes the process of building a pipeline instance from a pipeline template according to service selection. Section \ref{sec:heuristics} introduces the quality metrics used in service selection and the heuristic solving the service selection problem. Section \ref{sec:experiment} presents our experimental results. Section \ref{sec:related} discusses the state of the art and Section \ref{sec:conclusions} draws our concluding remarks.
