Persistent Identifier (PID)

A Persistent Identifier (PID) is a long-lasting reference to a document, file, web page, or other digital object. PIDs are unlike Uniform Resource Locators (URLs) because they cannot break. They are usually provided by services that create identifiers that consistently point to the same digital object, despite its location moving over time.

The FAIR Principles suggest using PIDs to meet the objectives of open science.
