About DOIs
DOIs are widely used mainly to identify academic and government information, such as journal articles, research reports, data sets, and official publications.
The DOI for an object remains fixed over the lifetime of the object, while its location and metadata may change. Referring to an object by its DOI is supposed to provide a more sustainable link than simply using its URL.
