Self-Archiving and Digital Preservation Policy

Self-Archiving Policy

Diyala Journal of Engineering Sciences (DJES) supports authors’ rights to self-archive their scholarly work in accordance with the journal’s open-access policy. Authors retain the copyright of their published articles and may archive the preprint, accepted manuscript, or published version of record in personal websites, institutional repositories, subject repositories, academic networking platforms, or libraries without requiring additional permission from the journal or publisher.

Authors may make their accepted manuscripts or published articles publicly available immediately upon acceptance or publication, provided that DJES is acknowledged as the original place of publication and that full and correct citation details are provided. When the published version of record is deposited or shared, authors should include the article title, author names, journal name, volume, issue, page numbers or article number where available, DOI, and the URL of the published article.

Authors are encouraged to link deposited versions to the official published version on the DJES website whenever possible. Any deposited version should clearly identify the version of the manuscript being shared, such as preprint, accepted manuscript, or published version of record.

Authors may also deposit supplementary materials, datasets, software, codes, models, or protocols related to their published work where appropriate and in accordance with the journal’s Data Availability Policy, provided that ethical, legal, privacy, confidentiality, and proprietary restrictions are respected.

Digital Archiving and Preservation Policy

DJES is committed to the long-term preservation, accessibility, and integrity of its published scholarly content. The journal preserves its published articles through the journal website, the Iraqi Academic Scientific Journals (IASJ) platform, and its hosting and technical backup arrangements.

The journal aims to maintain reliable access to published articles, metadata, DOI information, bibliographic records, supplementary publication records, and links to any associated correction, expression of concern, or retraction notice where applicable. Published articles remain part of the scholarly record and will not be silently removed from the journal website or archive.

In addition to the journal website and the IASJ platform, DJES maintains backup arrangements for its electronic publishing system. These arrangements include backup copies of the journal system, files, metadata, database, published articles, and related publication records on an independent server located in a data center different from the main hosting server, in accordance with the journal’s hosting and technical support arrangements.

These preservation and backup arrangements are intended to support the restoration and continued availability of journal content in the event of technical failure, accidental data loss, website interruption, hosting transfer, cybersecurity incident, or other service disruption. If access through the journal website is temporarily interrupted, DJES will make reasonable efforts to restore access and preserve the availability of published content through its digital archive, backup copies, and the IASJ platform.

DJES will periodically review its digital preservation arrangements and may adopt recognized long-term preservation services, such as the PKP Preservation Network, LOCKSS, CLOCKSS, or Portico, where technically, institutionally, and financially feasible. The purpose of these arrangements is to protect the scholarly record and ensure that published content remains accessible to readers, authors, researchers, indexing services, and the academic community over time.
