Uniform Resource Name (URN)

German: Uniform Resource Name
Abbreviation: URN

In the internet, this is an identifier with which – unlike URLs – online resources can be permanently and uniquely identified and retrieved regardless of where they are stored. The URN of a resource can only exist once in each namespace; the German National Library manages and assigns URNs from the namespace “urn:nbn:de”.

URN namespace

German: URN-Namensraum
We also say: namespace

In the internet, this is a collection of unique identifiers (Uniform Resource Names, URNs) that show the context in which a resource (e.g. an e-book) is embedded. The German National Library manages and assigns URNs from the namespace “urn:nbn:de”; “nbn” stands for National Bibliography Number and is a namespace specifically intended for national bibliographies and managed cooperatively by the national libraries.
