Preservation and Archiving Policy

The Preservation and Archiving Policy of the Journal of Hematology and Clinical Research (JHCR) ensures long-term preservation, accessibility, and integrity of all published scholarly content. This policy establishes mechanisms for maintaining permanent digital access even in the event of technical failure or publisher discontinuation.

JHCR’s digital archiving infrastructure complies with global standards, including Portico, LOCKSS (Lots of Copies Keep Stuff Safe), and CLOCKSS (Controlled LOCKSS), guaranteeing redundancy and fail-safe data replication.

Preservation Systems and Partnerships

• Portico: Primary digital preservation partner ensuring content migration, format integrity, and access continuity for all journal volumes and issues.
• LOCKSS: A decentralized network that preserves content across multiple institutional libraries worldwide to safeguard against data loss.
• CLOCKSS: Controlled version of LOCKSS providing additional audit and authenticity certification of digital content.
• Institutional Backups: Redundant secure backups are stored on JHCR’s internal servers with biweekly verification and checksum validation.

Archiving Formats and Standards

All published articles and metadata are preserved in interoperable formats that ensure readability and compatibility across time and systems. Supported archival formats include:

• Full-text HTML (for browser-based reading and metadata extraction)
• PDF/A (ISO 19005-1 standard for long-term preservation)
• XML (CrossRef XML and JATS 1.1 for metadata and structure retention)
• DOAJ XML for open access indexing interoperability

Metadata Preservation and Harvesting

JHCR’s metadata is accessible through the OAI-PMH interface for integration with discovery services and digital repositories. Metadata includes titles, authors, abstracts, DOIs, publication dates, keywords, license, and rights information.

Each article includes persistent identifiers through CrossRef DOIs to ensure that the Version of Record can be retrieved even if journal hosting changes.

Redundancy and Backups

Redundancy is achieved by maintaining multiple copies of all published content across geographically dispersed servers. The journal performs automated weekly incremental backups and quarterly full backups with off-site storage.

Integrity and Authenticity Checks

JHCR employs checksum validation (MD5/SHA256) and file integrity monitoring to detect any corruption or unauthorized alteration. Periodic audits are conducted in partnership with Portico and LOCKSS network administrators.

Format Migration and Technology Updates

To safeguard against technological obsolescence, JHCR maintains migration protocols allowing conversion of content into newer formats as standards evolve. This ensures continuous readability regardless of platform or software updates.

Access Continuity and Retrieval

In the event of server downtime, Portico serves as the trusted dark archive ensuring access continuity. LOCKSS and CLOCKSS repositories enable participating libraries to restore content locally through verified nodes.

Authors, readers, and indexing agencies may continue accessing published material via DOI redirection to Portico-verified mirrors during temporary service interruptions.

Disaster Recovery and Continuity Plan

The publisher maintains a robust disaster recovery protocol covering both digital and operational continuity:

• Daily automated server monitoring and downtime alerts.
• Data replication across three geographic regions.
• Quarterly failover testing to validate disaster readiness.
• Restoration testing under simulated data loss scenarios.

Roles and Responsibilities

• Publisher (Heighten Science Publications Inc.): Oversees system-level backup, archiving, and preservation partnerships.
• Managing Editor: Ensures all new issues and articles are deposited to Portico and CrossRef with complete metadata.
• Technical Team: Conducts quarterly preservation audits and ensures OAI-PMH endpoint functionality.
• Authors: Encouraged to deposit published versions in institutional repositories (see Repository Policy).

Ethical Compliance and Transparency

This policy aligns with the ethical standards of COPE, DOAJ, and OASPA for transparency in scholarly communications. Preservation and archiving practices are disclosed on the journal’s website and reported in metadata records for indexing services.

Legacy and Historical Preservation

All previously published issues since the journal’s inception are digitized and deposited with Portico for permanent access. Legacy metadata is reconstructed to ensure version consistency across all back issues.

FAQs

Is my article permanently accessible even if the journal ceases operations?

Yes. Portico and CLOCKSS ensure perpetual accessibility under publisher discontinuation scenarios.

How often are backups performed?

Weekly incremental and quarterly full backups are conducted, verified by checksum validation.

What formats are preserved for long-term access?

HTML, PDF/A, and XML (CrossRef/JATS) formats are archived for redundancy and future compatibility.

Where can I access the OAI-PMH metadata?

The OAI-PMH base URL is available in the journal’s footer and indexed in DOAJ metadata records.

Does preservation include supplementary data and multimedia?

Yes, provided they are linked with a DOI and conform to repository standards (e.g., Zenodo, Dryad).
