Copyright and Licensing

Copyright in an article remains with its authors or other lawful right holders. Authorship, the right to be named and other moral rights protected by law are retained. The right holder and publication year are shown on each article page and in the published version. Part Four of the Civil Code of the Russian Federation applies (https://pravo.gov.ru/proxy/ips/?docbody=&nd=102110716).

Before publication, the authors and publisher agree the final article version and licensing terms. The journal's contracting party is the publisher identified in full on the About the Journal page. The right holder grants the publisher a worldwide, royalty-free, non-exclusive licence for the duration of copyright. The licensed work is the specific final article version and accompanying material owned by the right holder, identified in correspondence by title, author list, date and agreed version designation. Where there are multiple right holders, the editors obtain confirmation from each of them or a duly authorised representative.

The licence permits reproduction, publication and distribution of copies, making the work publicly available as part of the journal and its electronic archive, storage and backup, technical conversion into publication and machine-readable formats without changing the scientific content, and use of metadata to identify and index the publication. The publisher may grant the XMLLIB electronic library (https://xmllib.ru), the Russian Centre for Scientific Information (https://rcsi.science) and preservation and indexing organisations the rights necessary for these uses within this licence, including sublicensing in accordance with Article 1238 of the Civil Code. Granting full-text rights for preservation, assessment and internal analysis does not itself authorise a recipient to provide open access contrary to the selected access model.

To comply with the rules governing cooperation between scholarly journals and the White List operator, the right holder separately authorises the publisher to supply full articles to the Russian Centre for Scientific Information (https://rcsi.science) and grant it a royalty-free, non-exclusive licence to process and store full-text materials for the entire copyright term, use them to create search indexes and for machine learning of models, and distribute the resulting outputs under an open licence. These permissions follow paragraphs 5.2 and 6.2 of Appendix 1 to the methodology for compiling and categorising the White List, approved by interdepartmental working-group protocol No. DS/122-pr of 9 September 2025. They do not grant the public an open licence to the complete original article. Acceptance of these copyright permissions forms part of the expressly confirmed licensing terms; any required consent to the transfer and processing of personal data is obtained separately.

The author authorises the title, abstract, keywords, bibliographic information, authorship, affiliation and funding information and reference list to be made available as open metadata under CC0 1.0 (https://creativecommons.org/publicdomain/zero/1.0/), to the extent of the author's copyright and related rights. These terms cover metadata and do not automatically cover the full article. They do not override privacy rights, personal-data law, moral rights or third-party rights. Consents to processing and dissemination of personal data are obtained separately under the personal-data policy.

Before publication, the licensing terms are accepted through separate, express confirmation by the right holder and confirmation by the publisher by email, or through a signed agreement. Electronic correspondence must reliably identify the parties, the agreed article version and the accepted terms. The editors retain the correspondence and the applicable terms. Electronic written form is used in accordance with Articles 160 and 434 of the Civil Code (https://pravo.gov.ru/proxy/ips/?docbody=&nd=102033239). Sending a manuscript for assessment does not automatically grant a publication licence and does not replace any required personal-data consent.

The author confirms the necessary rights in supplied material and proper attribution of borrowed content. Right-holder permissions are supplied where the intended use exceeds applicable copyright exceptions and limitations. Lawful quotation is permitted to the extent justified by its purpose with attribution of the author and source; other statutory exceptions are subject to Articles 1273 and 1274 of the Civil Code. Editorial changes affecting substance are agreed with the authors.

The journal website publishes the article’s open metadata and does not host its full text. The full article is available through a free subscription in the XMLLIB electronic library (https://xmllib.ru). Its page on the journal website provides a direct link to the corresponding full text. No public Creative Commons licence is granted for the full text by default. Copyright remains with the identified right holders. Reading access and downloads permitted by the library do not authorise unrestricted reproduction, distribution or adaptation. Uses beyond express permissions and statutory copyright exceptions require the right holder's permission. Requests may be sent to the journal's email address. Article metadata remain available under CC0 1.0. An access-model change does not revoke previously granted open licences for individual publications.
