Papel: Provenance-Aware Policy Definition and Execution

摘要

Data processing is often restricted by contractual and legal requirements for protecting privacy and intellectual-property rights. Internet policies help control how and by whom data is processed. Policy conditions could depend on previous data processing and thus on the processing histories' temporal structure. However, existing policy languages don't allow for expressing the temporal aspects of such conditions. Papel (Provenance-Aware Policy Definition and Execution Language) uses provenance information to connect data-processing policies and histories and to map the processing histories' temporal structure to a graph structure.
