Abstract

A wide range of distributed application scenarios require presence awareness. Examples include computer-supported collaborative work (CSCW), collaborative browsing, chat-/audio-/video-conferencing Systems, e-commerce, tele-teaching, to name only a few. Presence awareness provides information like the location, idendity, activities and the neighbours of someone or something who or which is present somewhere. In this paper we introduce the entities involved in a general purpose model for presence awareness. The goal is to provide the necessary services to the various applications that make use of presence information.
