Persistent identifiers (PID)

A persistent identifier (such as DOIs, PubMed IDs, ISSN/ ISBNs, ORCIDs, GRID IDs, etc.) is a globally unique identifier that is permanently assigned to a resource.

Persistent Identifiers (PIDs) are an important component of Open Science and FAIR data practices.  PIDs ensure that research outputs are findable, accessible, interoperable, and reusable.

Benefits of Persistent identifiers

  • They are required by publishers, research funders, and universities,
  • They increase the discoverability and the accessibility of research outputs and researchers,
  • They enable sharing and reuse,
  • They facilitate the opportunity for system integrations and interoperability.
