Abstract. Today, most mobile applications use geo-referenced points of
interest (POIs) on location-based maps to call the user's attention to in-
teresting spots in the surroundings. The presentation of both, maps and
POIs, is commonly location-based but not yet adapted to the individual
user's needs and situation. To foster the user's information perception by
emphasising the location-based information that is most relevant to the
individual user, we propose the xPOI concept ­ the modeling, process-
ing, and visualisation of context-aware POIs. We introduce a data model
for xPOIs, supporting the exchange of xPOIs and define an architecture
