Alternative identifiers for a digital object

The alternative identifier element <altRecordID> allows one to use alternative record identifier values for the digital object represented by the METS document; the primary record identifier is stored in the OBJID attribute in the root <mets> element.

Examples

First example: expanding on the basic example, altRecordID reflects the Library of Congress Control Number (LCCN) associated with the manifestation “20023838”.

<metsHdr CREATEDATE="2006-05-09T00:00:00">
  <mets:agent ROLE="CREATOR">
    <mets:name>Rick Beaubien</mets:name>
  </mets:agent>
  <mets:altRecordID TYPE="LCCN">20022838</mets:altRecordID>
<mets:metsHdr>

In the second example, altRecordID reflects the University of California, San Diego’s internal identification code for the object; this example also reflects various uses of the role attribute on agent.

<metsHdr CREATEDATE="2004-02-22T00:00:00"
    LASTMODDATE="2004-03-16T00:00:00" RECORDSTATUS="production">
