Persistent identifiers for publications and data

A persistent identifier (PI or PID) for a publication is a warrant that the publication both can be found and retreived as well as distinguished from other similar publications. There are several formats for permanent identifiers. One and the same publication can be assigned severeral kinds of permanent identifyers.

Uniform resource name (URN)

Uniform resource name (URN) is a unique permanent identifyer that is assigned to digital resources in order to make sure that a resource is possible to find long term. The URN results in a persistent link to the resourse, regardless of where the resource is currently located and stored. 

All publications and posts registred in the DiVA publication database is automatically assigned an URN. The URN codes in DiVA is in the local format URN:NBN, where NBN stands for National bibliographic number.

The URN format is developed by the Internet engineering task force (IETF).

Digital object identifyer (DOI)

A Digital object identifyer (DOI), like URN, is a unique permanent identifyer that is assigned to digital resources in order to make them possible to find long term. The DOI results in a persistent link to the resourse, regardless of where the resource is currently located and stored. DOI is administred by an external agency, the International DOI foundation (IDF).

DOI is very useful in order to cross reference data when making publication analyses. When your publication has an DOI it should always be included when registring the publication in DiVA.

International standard book number (ISBN)

International standard book number (ISBN) is used as a unique ID for books, reports, theses and other publications of monographic character. Through ISBN it is possible to distinguish books/monographs with identical titles, as well as reworked versions and different editions of one and the same monograph.
