What does URN mean?

Uniform Resource Name (URN) is a type of Uniform Resource Identifier (URI) that provides a globally unique and persistent identifier for a resource.
URN is a specific type of URI that emphasizes the identity of a resource rather than its location. It is designed to be persistent and long-lasting, even if the resource's location changes over time.

Example:
An example of URN is the ISBN number which is used to uniquely identify a book.
urn:isbn:0451450523
In the above example, "urn" is the scheme identifier, "isbn" is the namespace identifier, and "0451450523 " is the unique identifier for the book within the ISBN namespace.
