What are the benefits of using copyrightMD that are not already available in other schemas, such as Dublin Core, MODS, MARCXML, or METSRights?
The metadata schemas mentioned above do not adequately accommodate — both in terms of extent and granularity — the range of essential descriptive information necessary to assess the copyright status of a given object. Dublin Core, Metadata Object Description Schema (MODS), and MARCXML, for example, are designed to capture descriptive metadata and have relatively few data elements for capturing copyright-specific data. METSRights was designed to capture both copyright, contract, and license data, but it only has data elements for rights holder name and contact information. Even if multiple schema such as MODS and METSRights are combined into a composite metadata record for a given digital object, essential copyright information will still be lacking. Digital license schemas such as XrML (eXtensible rights Markup Language) and ODRL (Open Rights Digital Language) may be able to contain copyright-specific data, but as they are used today their emphasis is on license conditions not on cop
