TY - GEN A1 - Ringelstein, Christoph A1 - Staab, Steffen T1 - PAPEL: Syntax and Semantics for Provenance-Aware Policy Definition N2 - The processing of data is often restricted by contractual and legal requirements for protecting privacy and IPRs. Policies provide means to control how and by whom data is processed. Conditions of policies may depend on the previous processing of the data. However, existing policy languages do not provide means to express such conditions. In this work we present a formal model and language allowing for specifying conditions based on the history of data processing. We base the model and language on XACML.
