URNs are intended to be permanent identifiers for a resource. If a resource's URL changes due to a change in location or access method, the URL that is mapped to the persistent identifier URN must also be changed, but the persistent identifier URN itself remains the same. If a resource is ephemeral and becomes inaccessible at some point in time, the status of its persistent identifier URN should be changed but the identifier itself should not be reassigned.
Using NRS Web Admin, you can change a persistent identifier's associated URL as well as the status of the persistent identifier or the URL.
Note about responsibility: Persistent identifiers URNs associated with digital objects stored and delivered through Harvard Library infrastructure are usually maintained programmatically by LTS. Persistent identifiers created for web resources outside of Harvard Library infrastructure must be maintained by the organization that created persistent identifiers.
To update a persistent identifier:
- Connect to NRS Web Admin.
