Abstract
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. The generic metadata container can be adapted to dynamically define access control rights to a range of objects by a range of users, including granted and denied access rights.
