Privacy Preference Ontology

   An ontology to create privacy preferences for Linked Data.

The Privacy Preference Ontology (PPO) is a light-weight Attribute-based Access Control (ABAC) vocabulary that allows users to describe fine-grained privacy preferences for restricting or granting access to non-domain specific Linked Data elements, such as Social Semantic Data. Among other use-cases, PPO can be used to restrict part of FOAF profiles records only to users that have specific attributes. It provides a machine-readable way to define settings such as "Provide my personal phone number only to my family or "Grant write access to my technical blog only to my co-workers
