The document discusses online presence and the need for semantics, interoperability, integration, and interaction when representing a user's online presence. It proposes an Online Presence Ontology to capture a user's presence status, current activities, available sharing spaces, and contextual rules to help adapt interactions based on a user's presence state. The ontology would provide an overall image of a connected space of felt presence online.
