ORCID iDs supply the verified identity, and the CRediT contributor role taxonomy supplies the verified action — publishers deposit both together in Crossref and DataCite metadata, which then push the paired role and identifier straight into each contributor’s ORCID record. That two-way link is what closes the loop between “who contributed” and “who this person verifiably is”.
Recording credit taxonomy author contributions is only half of a durable scholarly record. Without a persistent identifier attached to each role, a contribution statement is just free text — unverifiable, unsearchable, and impossible to reconcile across a researcher’s career. CRediT (Contributor Roles Taxonomy) is a controlled vocabulary of 14 standardised roles — such as Conceptualization, Data curation, Formal analysis, and Writing – original draft — used to describe the specific contributions individuals make to a research output. CASRAI originated the CRediT contributor role taxonomy in 2014; the standard is now stewarded by NISO as ANSI/NISO Z39.104-2022. This article is a developer-facing walkthrough of how ORCID, Crossref, DataCite, and JATS XML combine to make each role machine-readable and identity-verified.

What is the CRediT-to-ORCID link, and why does it matter?
An ORCID iD is a persistent digital identifier that distinguishes one researcher from every other researcher sharing a name, institution, or field. On its own, a CRediT role is just a label — “Formal analysis” attached to a name string carries no guarantee that the name string maps to one real, disambiguated person. Pairing the two closes that gap: the role states what was done, the ORCID iD verifies who did it.
This matters for three distinct audiences. Institutions use role-plus-identity data to evidence individual contribution in tenure and promotion files, particularly for early-career researchers whose specific input is otherwise buried in a long author list. Funders use it to trace who performed which type of work across grant-funded outputs. Publishers and infrastructure providers — Crossref, DataCite, JATS4R — use it to keep the scholarly record machine-readable rather than dependent on parsing free-text acknowledgements.
How does an ORCID iD get attached to a CRediT role?
The attachment happens at the manuscript-submission stage, not after the fact. When an author submits to a participating journal, the manuscript submission system (MSS) requires each co-author’s authenticated ORCID iD and asks the submitting or corresponding author to assign one or more of the 14 CRediT roles to every contributor. All named contributors are expected to review and agree their assigned roles before the manuscript proceeds.
CRediT has been integrated into Aries Systems’ Editorial Manager since 2016 and into Clarivate’s ScholarOne Manuscripts since 2018, and is available as a free plug-in for the Public Knowledge Project’s Open Journal Systems (OJS). Two optional refinements are supported but not mandatory under the CRediT standard itself: an individual can hold more than one role, the same role can be assigned to multiple individuals, and a publisher may optionally record a “degree of contribution” — lead, equal, or supporting — where several people share a role.
Note that CRediT does not define authorship. It describes the specific contributions made to a research output and is designed to complement, not replace, authorship criteria such as those set out by the ICMJE.
Developer reference: CRediT role IDs
For machine-to-machine interoperability, each of the 14 CRediT roles carries its own persistent role identifier (a UUID), issued by NISO. These IDs — not the plain-text role labels — are what should be embedded in JATS XML markup and passed through the Crossref/DataCite metadata pipeline alongside the contributor’s ORCID iD.

The JATS4R (JATS for Reuse) working group, a NISO initiative, publishes best-practice guidance for tagging these role IDs inside <contrib> elements in JATS XML, ideally under JATS 1.2 (JATS 1.1 can still carry CRediT tagging with minor adaptation). Marking up role and ORCID iD together at the XML level — rather than only in human-readable HTML — is the step that makes the taxonomy queryable at scale.
What happens to CRediT data after publication?
Once a manuscript is accepted, the publisher deposits the authenticated ORCID iDs and assigned CRediT roles inside the article’s metadata record. That record goes to Crossref for journal articles and books, and to DataCite for datasets and other non-article outputs. Crossref’s own strategy roadmap confirms that CRediT role fields are being added to its metadata schema for publisher deposit in 2026, extending machine-readable contribution data beyond the publishers who currently support it only through their own MSS integrations.
Both Crossref and DataCite maintain an auto-update integration with ORCID: once metadata is deposited and the researcher has granted permission, the publication record — including the specific CRediT role — is pushed automatically into the contributor’s ORCID record. No manual re-entry is required. Where a publication predates this pipeline, or where a publisher does not yet support automated deposit, a researcher can add the CRediT role to a work already listed on their ORCID record manually.
Common questions about ORCID and CRediT
What are the 14 CRediT contributor roles?
The 14 CRediT roles are Conceptualization, Data curation, Formal analysis, Funding acquisition, Investigation, Methodology, Project administration, Resources, Software, Supervision, Validation, Visualization, Writing – original draft, and Writing – review & editing. Each carries its own persistent role ID for machine-readable tagging in JATS XML and Crossref/DataCite metadata.
Do CRediT roles count as authorship?
No. CRediT is not designed to determine authorship. It describes specific contributions to a research output and is intended to complement, not replace, authorship frameworks such as the ICMJE criteria. A contributor can hold a CRediT role — for example, Data curation — without meeting the separate threshold for authorship credit.
How do I list author contributions?
Assign one or more CRediT roles to every contributor, agree the assignments with all co-authors before submission, and, where the journal supports it, attach each contributor’s authenticated ORCID iD in the manuscript submission system so the roles are captured in structured, machine-readable metadata rather than free text.
What should substantial contributions include to be credited as an author?
Under ICMJE criteria, authorship requires substantial contribution to the work’s conception, design, data acquisition, analysis, or interpretation; drafting or critically revising it; final approval of the published version; and agreement to be accountable for its accuracy and integrity — all four criteria together, not any one alone.
Implications and what’s next
For institutions and research offices, the practical implication is straightforward: an ORCID iD without linked CRediT roles, or CRediT roles recorded only as prose in an acknowledgements paragraph, both fall short of a queryable contribution record. Research administrators evaluating authorship disputes or preparing tenure files should request the structured, role-tagged version wherever a publisher offers it.
For developers and publishing-systems teams, the near-term action is to track Crossref’s 2026 metadata-schema rollout and adopt JATS4R’s tagging guidance now, so that role-plus-identifier pairs are captured at first deposit rather than retrofitted. As more manuscript submission systems and repositories adopt this pairing by default, the taxonomy’s original purpose — a transparent, disambiguated account of who did what — becomes something search and assessment systems can actually query, not just something a human reader can parse. Further background on the taxonomy’s individual roles is available in CASRAI’s CRediT roles reference and the broader CRediT hub.
