SystemMetadata-class

A class representing DataONE SystemMetadata, which is core information about objects stored in a repository
and needed to manage those objects across systems.  SystemMetadata contains basic identification, ownership,
access policy, replication policy, and related metadata.

Provides a flexible container to transport and
manipulate complex sets of data. These data may consist of multiple data files and
associated meta data and ancillary files. Individual data objects have
associated system level meta data, and data files are linked together using
the OAI-ORE standard resource map which describes the relationships between the files.
The OAI-ORE standard is described at <https://www.openarchives.org/ore>. Data packages
can be serialized and transported as structured files that have been created following
the BagIt specification. The BagIt specification is described at
<https://tools.ietf.org/html/draft-kunze-bagit-08>.
