Policy Enabled Next geNeration Internet

The Policy Enabled Next geNeration Internet (PENNI) project will lay the technical foundations for a policy, trust and transparency enabled decentralised Next Generation Internet (NGI), that can support intelligent agents that act on behalf of humans.

Our hypothesis being that decentralized applications that are able to understand constraints, in the form of goals, preferences, norms and usage restrictions, together with trust and transparency mechanisms will give humans more control over how their data is utilised and will foster trustworthiness in NGI applications, such as intelligent agents and devices.



This PENNI project is funded by the FWF Austrian Science Fund and the Internet Foundation Austria under the FWF Elise Richter and netidee SCIENCE programmes as project number V 759-N.

Project Team

Dr. Sabrina Kirrane, who is the Principal Investigator of the PENNI project, is an Assistant Professor at the Vienna University of Economics and Business Institute for Information Systems and New Media. Her research interests include security, privacy, and policy aspects of distributed and decentralized systems. For more information visit

Work Packages

In PENNI we combine Design Science together with Action Research in order to iteratively develop and refine the policy language(s), trust and transparency framework, and Internet communication protocols, that are necessary to a support policy, trust and transparency enabled decentralised Next Generation Internet. Concretely we will make the following contributions:

Work package 1

Context, Goals and Constraint Representation

This work package will demonstrate how contextual information and policies specified using RDF can be adapted/extended in order to enable data publishers to attach contextual information to data and knowledge. In addition, we investigate how agent goals, constraints and social norms in the form of policies.

Work package 2

Control, Trust and Transparency aware NGI Architecture

Building upon the analysis performed in WP1, motivated by the need for a human-centric NGI, whereby users have control over and trust in intelligent devices and agents that act on their behalf, in this work package we survey existing policy based trust mechanisms, evaluate several potential NGI architectures from a policies and trust perspective, and propose a trust aware architecture for the NGI.

Work package 3

Policy Aware Web Protocols and Query Mechanisms

This work package will investigate how standard protocols for accessing RDF data (and Metadata) via HTTP, such as the Linked Data Platform 1.0, the SPARQL 1.1 Protocol and the SPARQL 1.1 Graph Store HTTP Protocol can be extended in order to cater for a policy aware NGI that provides humans with control and transparency with respect to web based intelligent devices and agents, and their behaviour.
