The paper presents an ontology, OPPO, to describe fine-grained data practices in privacy policies of Online Social Networks (OSNs). It aims to fill gaps in existing models by providing detailed data practices from OSN privacy policies. OPPO allows for a greater level of transparency in evaluating these policies. The ontology is intended to let users, OSNs, and others query the formal ontological representations of data practices for specific details or the general level of detail they provide.
