Need to decide on copyright element(s)

[tyt3]

We should decide if we want to include all of the desired copyright data in the same field, separated by a delimiter OR if we want to break them out into separate fields:

• copyright_status = 'copyright': {'bs_exp':'accessCondition' > [copyright.status]'}, #I'm not sure if this is right
• copyright_holder = 'copyright': {'bs_exp':'accessCondition' > copyright > rights.holder > name'},
• copyright_note = 'copyright': {'bs_exp':'accessCondition' > copyright > rights.holder > note'},
  Below are a couple examples of the copyright data:

<identifier type="pitt">31735047439272</identifier>
  <accessCondition>
    <copyrightMD:copyright copyright.status="copyrighted" publication.status="published">
      <copyrightMD:rights.holder>
        <copyrightMD:name>Sandra Gould Ford</copyrightMD:name>
        <copyrightMD:note>Permission granted by owner/publisher</copyrightMD:note>
        <copyrightMD:contact></copyrightMD:contact>
      </copyrightMD:rights.holder>
      <copyrightMD:general.note></copyrightMD:general.note>
    </copyrightMD:copyright>
  </accessCondition>

  <identifier type="pitt">31735065150314</identifier>
  <accessCondition>
    <copyrightMD:copyright xmlns:copyrightMD="http://www.cdlib.org/inside/diglib/copyrightMD" copyright.status="unknown" publication.status="published"></copyrightMD:copyright>
  </accessCondition>
