Archiving policy

The journal ensures reliable long-term preservation of all published materials in accordance with international digital archiving standards and open access principles.

All published articles are stored in the journal’s electronic archive on the Open Journal Systems (OJS) platform, which guarantees permanent access for readers and authors.

To ensure long-term content preservation, the journal:

• performs regular backups of all materials;
• uses standardized digital storage formats;
• maintains stable URLs and DOIs.

In the event that the journal ceases its operations, the editorial board ensures the transfer of the complete archive to an appropriate institutional or subject repository to maintain open access to all published materials.

For the purpose of preserving scientific content:

- all issues of the journal are archived in the Vernadsky National Library of Ukraine;

- articles are deposited in institutional repositories of the universities with which the authors are affiliated.

Open Data Policy

The journal encourages authors to make all data supporting their research findings available in open repositories (institutional, national, or international) in accordance with FAIR principles. A DOI or other persistent data identifier should be included in the article metadata and/or in the Data Availability section.
