A Uniform Resource Name (URN) are general URIs that refer to resources without disclosing any location or proof of existence.
Syntax
urn:nid:data
URNs use namespace identifiers (nid) that are unique and registered with the Internet Assigned Numbers Authority. The data is commonly unique information such as serial numbers.
Example
Libraries and booksellers may use the International Standard Book Number (ISBN) system to catalog and uniquely identify materials in their collection, like so:
urn:isbn:9781098110338
