MULTIPLE COLLECTIONS OF USER-DEFINED METADATA FOR SELF-DESCRIBING OBJECTS

摘要

Exemplary embodiments provide the ability to associate multiple collections of metadata to objects. In one embodiment, a storage system comprises: a processor; a memory; at least one object, each object including content data; system metadata associated with each object; and a plurality of named collections of user-defined metadata associated with each object. Each named collection of the plurality of named collections is separately addressable by a request. In some embodiments, at least one named collection of user-defined metadata of one object of the at least one object includes an access control list, and the access control list of a named collection specifies permissible access to the named collection. The one object has an object-level access control list which specifies permissible access to the one object and which is different from the access control list for the named collection associated with the one object.
