“…Both Damiani et al [21] and Weitzner et al [101] focus on the access control mechanisms that are required to support new ac-cess control paradigms where user privacy is a key requirement. De Coi et al [22] and Bonatti and Olmedilla [10] investigate the interplay between trust, access control and policy languages. While, Ryutov et al [73] focus more on the data model, investigating access control requirements from a graph perspective, as opposed to the traditional hierarchical approach.…”

“…In order to better understand the potential of existing access control mechanisms, this paper provides an overview of a number of access control models, languages and frameworks. A set of access control requirements are collated from [102,21,101,22,10,73] and categorised according to four different dimensions (specification, enforcement, implementation and infrastructure) that are necessary from an access control perspective. These requirements are used not only to classify existing access control strategies but also to identify challenges that still need to be overcome.…”

In recent years we have seen significant advances in the technology used to both publish and consume structured data using the existing web infrastructure, commonly referred to as the Linked Data Web. However, in order to support the next generation of e-business applications on top of Linked Data suitable forms of access control need to be put in place. This paper provides an overview of the various access control models, standards and policy languages, and the different access control enforcement strategies for the Resource Description Framework (the data model underpinning the Linked Data Web). A set of access control requirements that can be used to categorise existing access control strategies is proposed and a number of challenges that still need to be overcome are identified.

“…However, in this domain, ontologies are even more advantageous if they are used in combination with policy languages such as Ponder, KAoS, Rei, PeerTrust, and XACML [54]. Typically defined over ontologies, policy languages provide a reliable mechanism for (rule-based) reasoning in open environments, such as PLEs, where the use of roles and institutions the users may belong to is not applicable [55]. Current policy languages allow for contextbased reasoning where one can only leverage the knowledge coming from the shared vocabulary (i.e., ontology) of a community and the individual's reputation in the community.…”

Personal learning environments on the Social Semantic Web

Today's students, being used to constant activity and multitasking in their everyday life, need a high level of social and creative engagement in order to learn; for them, highly interactive learning environments which allow for communication, collaboration, and authoring, are a must. In addition, modern learning theories stress the importance of interactivity and engagement of students for successful learning processes, whereas recent empirical studies provide evidence and confirm this. In this paper, we present how the integration of Social and Semantic Web technologies, often referred to as the Social Semantic Web (SSW), along with the Linked Data paradigm offer potentials for improving the interactivity of today's learning environments, while putting students in control of their learning process spanning across different tools and services. We identify the main principles on which such SSW-supported personal learning environments are based, and illustrate them through the design, implementation, analysis, and evaluation of DEPTHS (DEsign Patterns Teaching Help System)-a SSW-based interactive personal learning environment we have developed for the domain of software design patterns.
