DEFINITION
|
The descriptor identifier is used to reference or identify the entire record of metadata descriptions for a media item and exists at the top level for a PBCore description and its associated description document (XML). Best practice is to identify the all-encompassing reference to a media item's descriptions and associated formats/instantiations with an unambiguous string or number corresponding to an established or formal identification system if one exists. Otherwise, use an identification method that is in use within your agency, station, production company, office, or institution. If using a digital asset management system, media asset management system, or content management system, the identfier is often automatically assigned by the system once an entry or record is created. The key is that the identifier always be unique.
Another descriptor named formatIdentifier is used to reference or identify a particular rendition/instantiation of a media item. |

GUIDELINES
FOR USAGE
|
Best practice is to identify the resource by means of a string or number corresponding to an established or formal identification system generated within an international standard or as a local identification scheme. If using a digital asset management system, media asset management system, or content management system, the identfier is often automatically assigned by the system once an entry or record is created. The key is that the identifier always be unique.
PBcore recommends the use of the companion descriptor, identifierSource, to indicate who assigned a particular identification number or designation. Thus PBCore provides not only a locator number, but also indicates an agency or institution who assigned it. |
