***'''identifier (dc:identifier)''' = id of the media record - needs to be persistent and unique within Audubon Core file. It may be tempting to use the URL of the media as the identifier. However, we have seen multiple cases where media have moved, making the identifier not persistent. If you have multiple types of identifiers for a media, put the least stable here and the most stable in ac:providerManagedID | ***'''identifier (dc:identifier)''' = id of the media record - needs to be persistent and unique within Audubon Core file.

Note: dc:terms format and dc:type should match the type of the object returned by ac:accessURI (If ac:accessURI is not present, dc:terms format and dc:type should not be present either), especially in the case where ac:furtherInformationURL is used as an alternative to ac:accessURI. | Note: dc:terms format and dc:type should match the type of the object returned by ac:accessURI (If ac:accessURI is not present, dc:terms format and dc:type should not be present either), especially in the case where ac:furtherInformationURL is used as an alternative to ac:accessURI. | ||
