File Identifier
System generated UUID:• Automatically changes for new metadata• Can be saved to a template
− CARE – if this is done the same file identifier can be used for all metadata instances based on the template
− Delete the file identifier before saving the template− This forces the file identifier to be re-created when the
template is loaded
