    摘要: Methods, systems, and data structures for communicating object metadata are provided. A generic metadata container is presented that allows object metadata to be described in an extensible manner using protocol-neutral and platform-independent methodologies. A metadata scope refers to a dynamic universe of targets to which the included metadata statements correspond. Metadata properties provide a mechanism to describe the metadata itself, and metadata security can be used to ensure authentic metadata is sent and received. Mechanisms are also provided to allow refinement and replacement of metadata statements. Communication of metadata is expedited using hash digests to confirm metadata versions, and by piggybacking policy metadata requests and responses on other substantive data communication messages, thereby dynamically altering future communications.
