A Persistent Identifier (PID) is a unique code string attached to a digital resource. PIDs are needed for creating links between different items online or in a data network. They can refer to any information about an object – digital photographs, the museum collection that the object is part of, documents that are referring to the object, and more.
Digisam has now published a checklist of what you should think about when working with persistent identifiers. The checklist has been developed in collaboration with a number of experts and is meant to serve as a support for cultural heritage institutions. We would like to thank all those who have sent us their views and comments! The checklist can be found here.
