What is the Name Resolution Service (NRS)?
The Name Resolution Service (NRS) is a HUL service for creating, maintaining, and resolving persistent identifiers. Also called names or URNs, persistent identifiers are location-independent names for network-accessible resources. Name resolution is the process of converting a persistent identifier into the URL to the resource. If a resource moves or its access method changes, the mapping between the resource’s persistent identifier and URL is updated; but the persistent identifier remains unchanged and valid. Persistent identifiers provide curators and researchers with confidence that the URL they cite will always work. The NRS is comprised of two separate services: • An Oracle-based administrative service that manages the metadata necessary to perform naming services; and • An HTTP-based resolution service that performs naming resolution. For more information, see NRS Frequently Asked Questions.
