Modeling Online Presence

In this paper, we introduce the notion of Online Presence, a concept related to user's presence on online services. We identify interoperability issues in the field of exchange of the online presence data and propose a solution in building a common model for semantic representation of online presence data. We present the Online Presence Ontology (OPO) together with benefits such an ontology could bring.
