01
Platform continuity
Public article pages use canonical URLs, DOI links, XML sitemaps and OAI-PMH metadata. Historical OJS URLs are redirected to their corresponding ERSS records.
02
Version-of-record files
Migrated PDFs are verified by filename, file size, page count and SHA-256 checksum. The platform stores source URLs and import status in a dedicated provenance record.
03
Operational backups
The production architecture supports encrypted, versioned backups of the database and private file storage, off-site retention and scheduled restore drills. Backup configuration must be completed and tested by the publisher before launch.
04
Long-term preservation
The platform exports JATS XML, Dublin Core and OAI-PMH records to support repository deposit and future preservation arrangements. Participation in a dedicated preservation network must be verified before any public preservation badge is displayed.
