In this paper we discuss the use ofviewsto address the problem of providing useful answers to provenance queries while ensuring that privacy concerns are met. In particular, we propose ahierarchicalworkflow model, based on context-free graph grammars, in whichfine-graineddependencies between the inputs and outputs of a module are explicitly specified. Using this model, we examine how privacy concerns surrounding data, module function, and workflow structure can be addressed.
