DATA AND REPRODUCIBILITY
Research data typically refers to digital, machine-readable files and can be defined as the results of experiments and observations that enable the verification of research results. The Journal encourages Authors to post their data in standard formats that can be accessed and re-used by others.

The Journal follows the Findability, Accessibility, Interoperability, and Reuse of digital assets (FAIR) principles. It supports data integrity and encourages Authors to share the data associated with their research and any other information that supports it. The Journal also encourages Authors to share their data on social media, repositories, and personal and institutional websites.

The Journal supports the TRUST principles for digital repositories and encourages Authors to place the data in one of the repositories listed in OpenDOAR. Authors should also follow institutional and, if applicable, the funding body’s guidelines when choosing the platform to share their data.

Authors are also encouraged to cite the data in their manuscript or indicate how to access the data by providing the DOI or access number.

The Journal encourages Authors to share the VoR (Version of Record – final published version) and the AAM (Author Accepted Manuscript) together with the data associated with the research.

The Journal encourages Authors to review the information available on the HOW CAN I SHARE IT? page in order to determine how the published article can be shared.
