The entities contain a number of storage elements which store metadata relating to a given storage level, and relate to attributes or characteristics of the entity, the storage levels are arrranged in a number of mutually consistent hierarchical or non-hierarchical relationships with the storage level at each level above the lowest level relating to the metadata of the immediately lower level. A number of levels of business entities each have business elements related to business metadata. The business elements are linked to the media metadata stores at a storage level appropriate to the business metadata. |
