Abstract

Provided are data structures for use in storing data. A plurality of data structures are defined in a computer readable medium, wherein each data structure indicates a plurality of attributes and at least one function of a storage resource to store data. Policies are defined in the computer readable medium that associate data characteristics to data structures based on a correspondence of data characteristics and the attributes defined in the data structures, wherein each defined data structure is adapted to provide requirements to determine a storage resource to store associated data, and wherein the defined data structure is adapted to provide the storage resource with requirements for storing the data.
