Among other things, this document describes a computer-implemented method for storing and retrieving information about the locations of objects. The method can include receiving a first query that includes one or more terms identifying an object. The first query can be determined to include a command to store location information for the object. The first query can be parsed to determine identifying information for the object, and a location can be determined for the object. The method further includes identifying one or more attributes of the object that are not specified in the first query, and causing a first set of data to be stored that characterizes the identifying information for the objet, the location of the object, and the one or more attributes of the object.
