Abstract:
1. Method for controlling the distribution of metadata items to recording media and to devices for reading from and/or writing to recording media, wherein it comprises the steps of: adding a respective propagation property to individual metadata items, the respective propagation property defining to which recording media and to which devices the metadata items must propagate and on which recording media and in which devices the metadata items must be stored together with the respective propagation property, the respective propagation property having one of at least two predefined values, wherein a first value indicates that a metadata item must be propagated and wherein a second value indicates that a metadata item must not be propagated, retrieving the respective propagation properties from the individual metadata items at least when a recording medium is inserted into or removed from a device or when the device is powered up or down, and responsive to the retrieved respective propagation properties, propagating and storing those metadata items, whose respective propagation properties indicate that those metadata items must be propagated, together with their respective propagation properties in accordance with their respective propagation properties, wherein propagating and storing of the metadata items together with their respective propagation properties is forced by the respective propagation properties.
