01 Purpose and Scope

JPG seeks to maintain continued access to its published scholarly content and related metadata through stable journal URLs, persistent identifiers and responsible digital-preservation arrangements. The policy covers the journal’s published articles, issue-level metadata, article landing pages and associated full-text files to the extent supported by each archiving service.

Preservation of the published record is distinct from local backup: backups help recover an operating system, while preservation services are intended to protect access to scholarly content over time.

02 Journal Publishing and Archiving Infrastructure

JPG publishes through Open Journal Systems (OJS) and identifies the Public Knowledge Project Preservation Network (PKP PN) as a long-term archiving pathway. Successful preservation of a particular issue depends on eligibility, plugin configuration, deposit and acceptance by the preservation service. The editorial office should verify individual issue status in the OJS PKP PN plugin before reporting completed archival coverage.

03 Continuity Across Journal Platforms

JPG has used successive OJS platforms. Readers can access the journal through the following locations, subject to the availability of the historical systems:

The official Journal History page records the transition of platforms, including security and technical disruptions. When restoring or migrating records, editors should retain bibliographic metadata and existing DOI links wherever possible.

04 Author Self-Archiving and Reuse

Consistent with JPG’s open-access policy, authors retain copyright and may share and deposit their publications in institutional or other appropriate scholarly repositories, subject to correct acknowledgement of the first publication and the published article’s Creative Commons Attribution 4.0 International (CC BY 4.0) license.

• Include a full citation and DOI link when depositing the published version.
• Clearly identify whether a deposited file is a preprint, accepted manuscript or the published version of record.
• Respect research-participant confidentiality, third-party copyrighted material and other restrictions that are not superseded by the article license.

See Open Access Statement and Copyright Notice for the journal’s published licensing terms.

05 Continuity, Maintenance and Inquiries

The editorial office periodically reviews the accessibility of article pages, published files and archive links. If published content becomes temporarily unavailable, readers may request assistance through the Contact Editorial Office page. Long-term archiving claims and backup practices should be reviewed whenever OJS, the host server or preservation plugin is upgraded.
