A Uniform Resource Name (URN) is a unique identifier assigned to a resource to distinguish it across time and space without necessarily specifying its online location. In other words, it is an exclusive and constant name associated with a resource.
Here are some examples of URNs used in various fields:
– In the audiovisual sector: ISA
– For European directives: LEX
– In the book industry: ISBN
– For electronic products: EPC
For example, URN nomenclatures such as:
urn:isbn:978-2-912254-40-5
urn:uuid:
urn:publishing:book
