Persistent identifiers connected to preserved records.
What the service covers
A practical preservation workflow for journals that need reliable long-term access without adding technical burden to the editorial team.
Deposit preparation
We organize article files, issue structures, supplementary assets, and metadata into consistent preservation packages.
Structured formats
JATS XML, PDF, HTML, images, and supplementary files are checked and grouped so content remains portable.
Metadata quality
Article titles, authors, affiliations, abstracts, references, DOI records, and publication dates are reviewed for consistency.
Continuity checks
Routine checks help identify missing files, broken links, metadata gaps, and records that need attention.
Built around publishing operations
Preservation works best when it is part of the publishing workflow, not an emergency archive created years later.
- Review current journal assets and identify preservation gaps.
- Normalize article files, metadata, and issue-level organization.
- Prepare preservation packages for new and backfile content.
- Maintain a clear record of what has been preserved and what still needs follow-up.
Publisher deliverables
Preservation bundles
Organized article packages that can be stored, transferred, or used for future platform migration.
Access resilience
Stable files and metadata reduce the risk of losing access when websites, platforms, or vendors change.
Indexing support
Cleaner metadata and files make it easier to work with DOI, indexing, and discovery workflows.
Status reporting
Concise preservation status reports help publishers understand coverage and pending work.
Built on enterprise-grade infrastructure
Your content is protected by multi-region redundancy, tamper-proof storage, continuous integrity verification, and automatic recovery — across 7 globally distributed nodes.
Multi-region storage
Every preservation package is replicated across 7 geographically distributed nodes powered by Cloudflare R2, AWS S3, and Tencent Cloud COS — ensuring low-latency access and resilience against regional outages.
Immutable storage
Once deposited, preservation packages cannot be altered or deleted — even by administrators.
- S3 Object Lock with COMPLIANCE mode prevents deletion during retention period
- Bucket Versioning retains full version history of every object
- Write-Once-Read-Many (WORM) policy enforced at storage level
Integrity verification
Regular checksum validation ensures that every preserved file remains bit-for-bit identical to the original deposit.
- SHA-256 checksums computed at ingest and verified on a recurring schedule
- Cross-region consistency checks compare replicas across all nodes
- Automated alerts trigger if any checksum mismatch is detected
Automatic recovery
Damaged or missing files are automatically restored from healthy replicas — no manual intervention required.
- Self-healing replication detects and repairs degraded copies within minutes
- Point-in-time recovery allows rollback to any previous object version
- Disaster recovery tested quarterly with documented RTO < 4 hours
Full transparency, always
Publishers receive quarterly preservation status reports covering ingest completeness, integrity check results, storage metrics, and any corrective actions taken. We believe trust is built through visibility.
