Pepkio CRediT Matrix Builder

Standardized NISO Contributor Roles Taxonomy (CRediT) authorship statement generator and JATS XML metadata engine for academic papers.

What It Does

The pepkio-credit-matrix-builder Python package creates, audits, and formats contributor role matrices for multi-author scientific manuscripts. It maps author contributions across all 14 official NISO CRediT roles, supports role degree assignments (Lead, Equal, Supporting), and exports publisher-compliant statements for PLOS, Elsevier, Frontiers, Markdown, and JATS XML 1.3.

Features

• 14 NISO CRediT Roles: Full support for all official ANSI/NISO Z39.104-2022 categories.
• Granular Contribution Levels: Assign Lead, Equal, or Supporting degrees per author-role pairing.
• Multi-Publisher Formats: Output ready-to-paste statements for PLOS, Elsevier, Frontiers, and clean Markdown.
• JATS XML & CSV Export: Export machine-readable XML <contrib> metadata and tabular CSV matrices.
• Author Entity Parser: Parse raw author text lists into structured author records with ORCIDs.
• CLI & Python API: Scriptable interface for automated manuscript workflows and publishing systems.

Installation

pip install pepkio-credit-matrix-builder

Or using uv:

uv add pepkio-credit-matrix-builder

Quick Example

from pepkio_credit_matrix_builder import PepkioClient

with PepkioClient() as client:
    result = client.run({
        "action": "generate",
        "articleType": "empirical",
        "journalFormat": "plain",
        "authors": [
            {"id": "author-1", "name": "Dr. Elena Vasquez", "corresponding": True},
            {"id": "author-2", "name": "Alex Chen", "equalContribution": True}
        ],
        "assignments": {
            "author-1": {"conceptualization": {"assigned": True, "degree": "lead"}},
            "author-2": {"investigation": {"assigned": True, "degree": "lead"}}
        }
    })

    print("CRediT Statement:\n", result.result["statement"])

Typical Use Cases

• Journal Submissions: Format compliant author contribution statements for PLOS ONE, Elsevier, Springer Nature, and Frontiers.
• Authorship Audits: Establish transparent role attribution among co-authors prior to manuscript submission.
• JATS Metadata Generation: Generate machine-readable XML <role vocab="credit"> tags for publisher ingest.

Scientific Background

The Contributor Roles Taxonomy (ANSI/NISO Z39.104-2022) replaces ambiguous author order with explicit attribution across 14 practical roles covering ideation, technical investigation, data analysis, and manuscript preparation.
