As disclosed herein, an apparatus receives data from sensors that are arranged in a repository facility so they can capture repository locations of the repository facility and a path in the repository facility. It derives an identification and a position of an object in the repository facility from the received data. It causes storage of the position of the object in association with its identification if a position is not yet stored for the object. If a position is already stored for the object, the apparatus checks the position on the basis of the derived position and causes storage of the derived position in the event of a change. On obtaining an enquiry in regard to the position of an object in the repository facility, the apparatus reads a position of the object, stored in association with the identification of the object, and provides information regarding the position.
