Spectrum: Journal of Science Education recognizes the importance of preserving scholarly publications as part of the permanent academic record. The journal seeks to ensure that published articles, supplementary files, bibliographic metadata, and related publishing information remain accessible and recoverable over the long term.

Digital preservation activities are intended to reduce the risk of data loss resulting from technical failure, system migration, accidental deletion, or other disruptions affecting the journal publishing platform.

The journal maintains periodic backups of the digital resources required for journal operation and publication. Depending on the technical infrastructure, backup materials may include:

• Journal databases;
• Published article files;
• Article metadata;
• Supplementary materials;
• Journal configuration data;
• Editorial and publication-related files;
• Website and system files necessary for restoration of journal services.

Backups are intended to support recovery and restoration when data loss or technical disruption occurs.

Published articles are preserved together with essential bibliographic information, including title, author information, abstract, keywords, issue information, publication date, and other relevant metadata.

Where supplementary files form part of the published scholarly record, the journal will seek to retain those files together with the associated article.

Spectrum recognizes metadata as an important component of digital preservation. The journal seeks to maintain accurate bibliographic and publication metadata to support article discovery, citation, repository integration, indexing, and long-term identification of published content. Metadata may be distributed through appropriate scholarly infrastructure and metadata-harvesting mechanisms when available.

As an Open Journal Systems (OJS)-based journal, Spectrum supports standardized mechanisms for the dissemination and harvesting of journal metadata where enabled within the publishing platform. Such mechanisms can improve interoperability between the journal, repositories, library services, academic search systems, and other scholarly information infrastructures.

PT. Gammabeta Edu and Tech supports the preservation of Spectrum's digital publishing infrastructure and scholarly content. Copies of journal files and relevant publication data may be retained within publisher-managed or institutional storage systems as part of the journal's continuity and recovery strategy.

Spectrum supports responsible author self-archiving. Subject to the applicable Copyright and License Policy, authors may deposit or share permitted versions of their articles through institutional repositories, subject repositories, academic webpages, or other appropriate scholarly platforms.

Where possible, archived copies should contain the complete citation of the published article and a link to the official journal version. Author self-archiving provides an additional mechanism for increasing both the preservation and scholarly visibility of published research.

Where persistent identifiers such as Digital Object Identifiers (DOIs) are assigned, they help maintain stable identification and linking of published articles. Persistent identifiers complement, but do not replace, the journal's underlying digital preservation and backup practices.

If the journal website, publishing platform, server environment, file format, or technical infrastructure changes, Spectrum will seek to migrate published content and essential metadata to the new environment without compromising the integrity of the scholarly record. Preservation planning should consider technological changes that may affect future accessibility of digital materials.

If Spectrum ceases publication, the publisher will seek to preserve previously published scholarly content and maintain reasonable access to the journal archive. Where appropriate and technically possible, published files and metadata may be transferred or maintained through another repository, publisher-controlled archive, institutional system, or appropriate digital-preservation service.

Corrections, retractions, expressions of concern, and other formal post-publication notices form part of the scholarly record and should be preserved together with the affected publication. Spectrum does not support the silent removal or alteration of substantive published content. Relevant changes are handled transparently in accordance with the journal's Retraction, Correction and Withdrawal Policy.

Spectrum may participate in recognized external digital-preservation networks or services as the journal's technical infrastructure develops. Examples of such preservation initiatives within scholarly publishing may include PKP Preservation Network (PKP PN), LOCKSS, CLOCKSS, or comparable services.

Reference to these services in this policy does not indicate current participation unless such participation is explicitly confirmed on the journal website. Any external preservation service formally adopted by Spectrum will be identified transparently.

This Archiving Policy should be read together with Spectrum's Open Access Policy, Copyright and License Policy, Publication Ethics, and Retraction, Correction and Withdrawal Policy. Together, these policies support the accessibility, preservation, legal use, and integrity of the journal's scholarly publications.
