The ORCID Researcher Advisory Council (ORAC) is a diverse group of researchers who provide valuable perspectives and advice to ORCID staff and the ORCID Board to ensure that ORCID provides value and utility to researchers and facilitates research and innovation.

In a journal article or manuscript a sample identified by IGSN SSH000SUA may look like this (tagged IGSN): IGSN:SSH000SUA

Unlike many other persistent identifiers, an IGSN is used not only used by machines but also needs to be handled by humans.

Appropriate identifiers Requirement: PIDs appropriate to the digital object type being persistently identified.

withdrawing content withoutposting a notification (“Tombstone Page”) andupdating the record's URL/metadata with DataCite

When content underlying a DOI is updated, we recommend updating the DOI metadata and, for major changes, assigning a new DOI. For minor content changes, the same DOI may be used with updated metadata. A new DOI is not required. For major content changes, we recommend assigning a new DOI and linking the new DOI to the previous DOI with related identifiers.

To enable easy usability for both humans and machines, a DOI should resolve to a landing page that contains information about the DOI being resolved. It is the responsibility of the entity creating the DOI to provide such a landing page. The following are best practices for creating well-formed DOI landing pages.

there may be infrequent cases where it is not desirable for the item described by a DOI to be available publicly, such as in the case of research retraction. In these cases, it is best practice to still provide a "tombstone page", which is a special type of landing page describing the item that has been removed.
