One more and more upcoming challenge for IT systems used in the Facility Management domain is the automated acquisition and processing of distributed heterogeneous data. Especially for approval or maintenance processes the mobile access to necessary data constantly gains significance. But because of their limited size particularly mobile devices require new ways for representing the needed amount of information. This conceptual paper discusses new approaches of knowledge acquisition and representation, which enable the efficient support of facility managers in their daily tasks. The underlying research project develops concepts and solutions for the semantic modelling and linking of distributed data as well as its context-based representation on a mobile device via Augmented Reality.
