Common questions
FAQ
Is NISO’s taxonomy a newer or updated version of CRediT?+
No. It is the same 14-role vocabulary, same definitions, and same optional lead/equal/supporting qualifiers -- formally published under NISO’s standards process rather than superseding or extending the original CASRAI-stewarded version.
Do I need to update old CRediT statements to reference the NISO standard number?+
No. Existing published contributor statements that say "CRediT" remain accurate and complete; there is no retroactive renaming requirement.
Does CASRAI still have a role in CRediT?+
CASRAI stewarded CRediT from 2014 until the February 2022 standardization and continues to host reference material and adoption guidance. Ongoing formal maintenance and the change-control process now sit with NISO’s standing committee.
Which name should appear in a manuscript’s contributor statement?+
"CRediT" -- that is the term journal systems, editorial policies, and author instructions use. The formal ANSI/NISO Z39.104-2022 citation belongs in policy or standards-reference documents, not the manuscript’s own contributor statement.
Is there a separate NISO document that competes with or replaces CRediT?+
No. ANSI/NISO Z39.104-2022 is titled "CRediT, Contributor Roles Taxonomy" -- NISO published CRediT itself as the standard; it did not create an alternative taxonomy alongside it.
