Persistent Identifier (PI)

A maintained reliable pointer to the identity, and also possibly its location, of a digital object through time.

There are many types of PIs: the ISBN for physical books, and in some cases also electronic publications, provides a unique name, but not the location of the item. In the digital world the URI/URN identifies the resource, while the URL also locates the resource. The term Digital Object Identifier (DOI) is also used.
