Persistent identifier (PID)1
A persistent identifier is a long-lasting reference to a digital resource. Typically it has two components: a unique identifier; and a service that locates the resource over time even when it’s location changes. The first helps to ensure the provenance of a digital resource ( that it is what it purports to be), whilst the second will ensure that the identifier resolves to the correct current location.
Examples of PIDs include:
-
Digital Object Identifier (DOI): DOIs are digital identifiers for objects (whether digital, physical or abstract). As well as the object identifier, DOI has a system infrastructure to ensure a URL resolves to the correct location for that object. More information can be found on the DOI website.
-
ORCID: This identifier is key for researchers disambiguating themselves from other researchers with similar names, associating them with the proper institution as well as receiving the credit for their research outputs. More information can be found on the ORCID website.
-
International Standard Name Identifier (ISNI): This identifier provides information about the institution where a researcher worked while the research was undertaken. More information can be found on the ISNI website.
