A persistent identifier (PID) is a long lasting reference to a resource, such as a collection item, book, or object. It can also refer to canonical metadata, e.g. a creator of an object. Examples of PIDs include archival resource keys (ARKs), persistent URIs and digital object identifiers (DOIs). Generally a persistent identifier can be presented as an actionable link which can be used to access the resource or metadata about the resource.
Persistent identifiers have a number of potential benefits. They allow you to reliably link to your collection around the web and in publications. They also make it easier to track the use of your resources where they are cited elsewhere.
This resource describes the different aspects of developing persistent identifiers (PIDs) in the context of Heritage Collections. Following consultation through May 2021, the resource is now available in a revised version and will be maintained until the conclusion of the Towards a National Collection programme in 2025.
