摘要：
A method is used in controlling access to XAM metadata. An object derived from a set of content is stored in an object addressable data storage system. The object has an object identifier. Storage system specific metadata is added to the object. The storage system specific metadata is accessible when the object is retrieved using the object identifier. Based on sub-object access control, a retrieving application is allowed to have access to only a subset of the object.
