Using a Digital Object Identifier (DOI) allows electronic documents to be referenced in a stable, globally unambiguous and non-location-dependent manner. Once assignes, it guarantees reliability in citing sources even if the Uniform Resource Locator (URL) changes. Once assigned as the permanent Identifier, it allows for citation in scientific documents.
DOIs, themselves not to be called up directly in a browser, are matched to the relating URL by a resolving-service. The persistent resolution of these links is under maintenance of the International DOI Foundation (IDF).
