Reasoning with data flows and policy propagation rules

In: Semantic Web, vol. 9, no. 2, 2018

Knowledge Components and Methods for Policy Propagation in Data Flows

PhD Thesis. Knowledge Media Institute Faculty of Science, Technology, Engineering and Mathematics The Open University, 2018

In this thesis, we tackle the problem of policy propagation in data flows - an expression that refers to the way data is consumed, manipulated and produced within processes. We pose the question of what kind of components are required, and how they can be acquired, managed, and deployed, to support users on deciding what policies propagate to the output of a data-intensive system from the ones associated with its input.
