4.10. Resource Identifier
Label: Identifier
Element Description: A string or number used to uniquely identify
the resource. Examples for networked resources include URLs and URNs
(when implemented). Other globally-unique identifiers, such as
International Standard Book Numbers (ISBN) or other formal names are
also candidates for this element.
Guidelines for creation of content:
This element can also be used for local identifiers (e.g. ID numbers or
call numbers) assigned by the Creator of the resource to apply to a
particular item.
