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.
