Persistent IdentifierThe Persistent Identifiers (PI) is a number assigned to a digital object (for example a publication or dataset). By using the stable Uniform Resource Name (URN), objects will no longer be identified by the unstable Uniform Resource Locator (URL). The advantage is clear: when an object shifts to another repository, its URL will change, but its URN will remain the same. urn:nbn:nl:ui:32-341831
