Working group Track A
CRediT extensions and adjacent contribution vocabularies
The CRediT extensions working group stewards the next generation of contribution vocabulary, extending the 14-role CRediT taxonomy (NISO Z39.104-2022) to acknowledged contributors, peer reviewers, technical staff and research-software engineers. It coordinates with NISO, publishers and infrastructure providers so that contribution metadata flows end-to-end from manuscript submission through Crossref and ORCID into institutional CRIS systems. The group preserves CRediT's minimalism while addressing the gaps that authors, editors and funders have identified since the 2022 standard.

FAQ
Frequently asked
- How do you write an author contribution statement?
An author contribution statement lists each author alongside the CRediT role or roles they performed, drawn from the 14 standardized roles defined in NISO Z39.104-2022, such as conceptualization, methodology, or writing. CASRAI's CRediT extensions working group is developing degree-of-contribution qualifiers (lead, equal, supporting) so statements can also show how much each author contributed to a given role. Statements built this way map directly to metadata fields that can flow through Crossref and ORCID, keeping the published statement and the underlying record consistent.
- What does a credit author statement sample look like?
A typical CRediT-based statement pairs each author with one or more of the taxonomy's 14 defined roles, such as "data curation" or "formal analysis," instead of a free-text description of who did what. The working group's current scope extends this pattern beyond the author byline to acknowledged contributors, peer reviewers, and research software engineers, and adds degree-of-contribution qualifiers so a sample statement can also indicate whether a role was performed in a lead, equal, or supporting capacity. This keeps contribution reporting structured and consistent across articles.
- What is credit taxonomy authorship?
CRediT taxonomy authorship describes each author's specific contributions using the 14 standardized roles set out in NISO Z39.104-2022, rather than listing authors as an undifferentiated group. CASRAI's CRediT extensions working group builds on this by addressing gaps identified since the 2022 standard, including recognition for peer reviewers, technicians, core-facility staff, and research software engineers who contribute to a study but fall outside the traditional author byline. It coordinates with NISO, publishers, and infrastructure providers so this contribution metadata flows through JATS, Crossref, and ORCID into institutional CRIS systems.
- What does this working group do?
The CRediT extensions and adjacent contribution vocabularies working group is the community body that drafts, reviews and ratifies dictionary entries for the CRediT extensions and adjacent contribution vocabularies domain. It maintains scope, cross-walks to adjacent standards and the cadence of public review. Its remit is summarised on this page; the canonical terms it stewards live at /dictionary/domain/credit-extensions.
- Who can apply to join?
Working-group membership is open to qualified practitioners — researchers, research-office staff, librarians, publishers, repository managers, integrity officers, CRIS administrators, regulators and funders. Institutional membership is not required. The qualification test is competence and time, not affiliation. Apply via the working-group application form.
- What is the time commitment?
Cadence: Quarterly virtual sessions; two release windows per year (March and September).. Time commitment averages four hours per quarter for an active member, more for a chair. Asynchronous review happens between meetings via email. Chairs are recognised on the editorial masthead and serve a two-year term, renewable once.
- How are seats allocated?
Each working group has 12 community seats plus a chair and (optionally) a co-chair. Seats are filled by an open call reviewed against a published rubric: domain expertise, institutional diversity, regional balance, and an explicit slot for early-career researchers. Applications for the 2026 forming round are open and candidates are currently under review — see how to apply.
- Can my institution sponsor a seat?
Institutional sponsorship is welcome but is not a route to a guaranteed seat. Sponsors support meeting infrastructure, public-comment publication and contributor honoraria; they receive named acknowledgement on the working-group page and in release notes. Sponsorship enquiries go to [email protected]. Seat selection remains on merit.
