Data & Code Availability
EJAS’s expectations for data- and code-availability statements, repositories and reproducibility in applied- and natural-science research.
Openness about the data, code and materials behind published findings strengthens confidence in research and supports reproducibility — a core value in the applied and natural sciences. EJAS therefore encourages authors to share these resources to the fullest extent that ethics, safety and law permit.
Data and code availability statement
Each research article should include a statement explaining whether, and how, the data and code supporting the results may be accessed. Where they cannot be shared, the statement should say so and explain why. Typical formulations include:
| ▸ | “The data and code supporting this study are openly available in [repository] at [DOI or URL].” |
| ▸ | “The data are available from the corresponding author on reasonable request.” |
| ▸ | “The data are not publicly available owing to confidentiality, safety or legal restrictions.” |
Recommended practice
Where sharing is appropriate, deposit data and code in a recognised, citable repository that issues a persistent identifier, and cite them in the reference list. Use discipline-specific repositories where they exist (for example for sequences, structures, crystallographic, spectral or geospatial data), and general-purpose repositories such as Zenodo, Figshare, the Open Science Framework or Harvard Dataverse otherwise. Report methods in enough detail to permit reproduction, and share materials and protocols where helpful.
Restricted and personal data
The sharing of data must never override confidentiality, consent terms, safety or data-protection obligations. Personal data must be anonymised before sharing (see Research Ethics & Consent and the Privacy Policy).
Funding disclosure
Authors must also state all sources of funding for the research, including grant numbers, or confirm that the research received no specific funding.
