Transparency & Data Policy (jpart-transparency-and-data)

JPART does not merely encourage sharing — it requires authors, where ethically possible, to

**publicly release all data and software code underlying the published paper as a condition of

publication, and every paper must carry a Data Availability Statement**. Build the package as you go

so acceptance does not stall on materials.

When to trigger

• Building the reproducibility/replication package and the Data Availability Statement
• A manuscript is heading toward acceptance and you need materials in shareable form
• Data cannot be fully shared (privacy, ethics, legal/provider restrictions) and you need the exemption path
• Preparing or linking a preregistration / pre-analysis plan (JPART accepts blinded pre-reg reports)

What JPART requires (verify current wording on the policy page)

1. Public release of data and code. As a condition of publication, release the data and the software

code that produced the results — in a trusted, citable public repository with a persistent identifier

(e.g., a Dataverse or OSF deposit), not a personal website or transient cloud link.

1. Data Availability Statement. A mandatory statement in the manuscript describing what is available,

where, and under what access terms.

1. Reproducible materials. Data, code, and documentation sufficient to regenerate every reported

result: a master script + README + pinned versions + seeds.

1. Preregistration where applicable. For experiments, link the (blinded) pre-analysis plan and mark

confirmatory vs. exploratory analyses; the journal accepts blinded pre-reg reports for review.

When data cannot be shared (exemption path)

• Explain why in the Data Availability Statement (ethical/privacy concerns or provider restrictions).
• Provide README instructions on exactly how others can obtain the data (access process, contact).
• Where possible, provide synthetic data resembling the restricted data so the code can be run.
• Exemptions typically require explicit editor approval — do not assume a quiet opt-out.

Build-as-you-go checklist

• [ ] One master script regenerates every table and figure from raw/constructed data
• [ ] README documents data provenance, construction steps, and how to reproduce each exhibit
• [ ] Seeds set and reported for every stochastic step
• [ ] Software/package versions pinned (renv.lock / requirements.txt / recorded installs)
• [ ] Exhibit numbers in the manuscript match the package output exactly
• [ ] Data Availability Statement drafted (what / where / access terms)
• [ ] Public deposit prepared in a citable repository with a persistent identifier
• [ ] Restricted data: exemption note + access instructions + synthetic data + editor approval where needed
• [ ] Preregistration / pre-analysis plan linked (blinded) where applicable

Anti-patterns

• Treating the deposit as a post-publication afterthought (release is a condition of publication)
• Depositing code that does not actually reproduce the printed tables/figures
• A personal URL instead of a trusted citable repository
• Claiming data are restricted without an access path, synthetic substitute, or editor approval
• Undocumented, un-seeded, unpinned code that "works on my machine"

Output format

【Data + code release】public, citable repository staged? [Y/N]
【Reproduces tables/figures?】master script verified locally? [Y/N]
【Data Availability Statement】drafted? [Y/N]
【Documentation】README + provenance + seeds + pinned versions? [Y/N]
【Restricted data?】exemption note + access path + synthetic data + editor approval?
【Preregistration】linked (blinded) where applicable? [Y/N/NA]
