The Contributor Roles Taxonomy (CRediT) is a community-developed framework comprising 14 standardized contributor roles designed to represent the diverse types of contributions commonly made to scholarly research outputs, including journal articles. Developed to complement traditional authorship practices, CRediT provides a structured and transparent approach to identifying individual contributions to research and publication processes. Beyond its application in scholarly publishing, contributorship information derived from the CRediT taxonomy also supports research assessment, expert identification, research integrity, transparency, and accountability.

Note that authors may have contributed through multiple roles, and those who contributed to the research work but do not qualify for authorship should be listed in the acknowledgments.

The roles and their descriptions are shown in the table below.

No.	Role	Description
1	Conceptualization	Ideas, formulation, or evolution of overarching research goals and aims.
2	Data Curation	Management activities to annotate (produce metadata), scrub data, and maintain research data (including software code, where it is necessary for interpreting the data itself) for initial use and later reuse.
3	Formal Analysis	Application of statistical, mathematical, computational, or other formal techniques to analyze or synthesize study data.
4	Funding Acquisition	Acquisition of financial support for the project leading to this publication.
5	Investigation	Conducting research and the investigation process, specifically performing the experiments, or data/evidence collection.
6	Methodology	Development or design of methodology; creation of models.
7	Project Administration	Management and coordination responsibility for research activity planning and execution.
8	Resources	Provision of study materials, reagents, materials, patients, laboratory samples, animals, instrumentation, computing resources, or other analysis tools.
9	Software	Programming, software development, designing computer programs, implementation of the computer code, and supporting algorithms; testing existing code components.
10	Supervision	Oversight and leadership responsibility for the research activity planning and execution, including mentorship external to the core team.
11	Validation	Verification, whether as a part of the activity or separate, of the overall replication/reproducibility of results/experiments and other research outputs.
12	Visualization	Preparation, creation, and/or presentation of the published work, specifically visualization/data presentation.
13	Writing Original Draft	Preparation, creation, and/or presentation of the published work, specifically writing the initial draft (including substantive translation).
14	Writing Review & Editing	Preparation, creation, and/or presentation of the published work by those from the original research group, specifically critical review, commentary, or revision, including pre- or post-publication stages.
