Taxionomia Credit Authors (CRediT)

The Authorship Contribution Taxonomy is a high-level categorization system composed of 14 functional roles, designed to represent in a standardized and transparent way the different types of individual contributions made by authors in the production of scientific and academic knowledge.

Each role described in the taxonomy corresponds to a specific aspect of the research process, covering everything from project conception to writing, data curation, and validation of results. The model acknowledges that scientific authorship is multifaceted and seeks to highlight, in a granular way, the real involvement of each collaborator in the development of the work.

The adoption of CRediT aims to:

  • Increase transparency in the attribution of authorship and responsibilities;

  • Facilitate the traceability of individual contributions;

  • Improve systems of recognition, credit, and accountability in scientific publishing;

  • Reduce authorship disputes by making each individual’s participation explicit.

It is important to note that a single author can be associated with multiple roles, reflecting the complexity and interdisciplinarity inherent in contemporary research. Likewise, a single role may be assigned to more than one author when collaboration is shared in a given function.

CRediT is compatible with the principles of editorial best practices recommended by international institutions such as COPE (Committee on Publication Ethics), ICMJE (International Committee of Medical Journal Editors), and platforms such as ORCID, and is being integrated into submission and editorial systems of high-impact journals.

 

 

Role

Definition

Conceptualization

Ideas; formulation or evolution of overarching research goals and aims.

Data Curation

Management activities to annotate (produce metadata), clean data, and maintain research data (including software code, where necessary for interpreting the data itself) for initial use and later reuse.

Formal Analysis

Application of statistical, mathematical, computational, or other formal techniques to analyze or synthesize study data.

Funding Acquisition

Acquisition of financial support for the project leading to this publication.

Investigation

Conducting a research and investigation process, specifically performing the experiments or data/evidence collection.

Methodology

Development or design of methodology; creation of models.

Project Administration

Management and coordination responsibility for the research activity planning and execution.

Resources

Provision of study materials, reagents, materials, patients, laboratory samples, animals, instrumentation, computing resources, or other analysis tools.

Software

Programming, software development; designing computer programs; implementation of the computer code and supporting algorithms; testing of existing code components.

Supervision

Oversight and leadership responsibility for the research activity planning and execution, including mentorship external to the core team.

Validation

Verification, whether as part of the activity or separately, of the overall replication/reproducibility of results/experiments and other research outputs.

Visualization [of dada (infographic, flowchart, table, graph)]

Preparation, creation, and/or presentation of the published work, specifically visualization/data presentation.

Writing – Original Draft

Preparation, creation, and/or presentation of the published work, specifically writing the initial draft (including substantive translation).

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.
