Digital archiving & preservation

Current preservation measures

All published content — article PDFs, HTML full text, figures, supplementary files, and metadata — is protected by the publisher's redundant backup infrastructure:

• Multiple copies of the full published corpus are maintained on geographically and technically independent systems.
• Backups run on a regular schedule and are verified for integrity, so that content can be restored completely in the event of hardware failure, data corruption, or hosting disruption.
• Journal metadata is additionally distributed beyond our own systems through DOI registration (see below), which means the bibliographic record of every article exists independently of Lumora's servers.

Long-term preservation commitment

Redundant backups protect against technical failure; true digital preservation must also protect against organisational failure — the possibility that a publisher ceases to operate. For journals hosted on OJS (Open Journal Systems), the recognised solution is the PKP Preservation Network (PKP PN), which preserves journal content in a distributed LOCKSS-based network and makes it available if the journal ever disappears from the web.

In the interest of transparency: Lumora journals are not yet enrolled in the PKP Preservation Network or another LOCKSS/CLOCKSS-class dark archive. Enrolment in PKP PN (or an equivalent recognised preservation network) is a stated commitment of this policy, and this page will be updated to name the active preservation arrangement once enrolment is complete. Until then, the redundant backup measures above, DOI persistence, and authors' unrestricted self-archiving rights (below) together ensure that Lumora content is not held in a single vulnerable location.

DOI persistence

Every Lumora article is assigned a Digital Object Identifier (DOI) registered with Crossref. DOIs provide:

• Permanent citability — the DOI, not the URL, is the persistent address of the article. If our platform, domain, or hosting arrangements ever change, DOIs are updated to resolve to the new location, so existing citations never break.
• Independent metadata — the article's bibliographic metadata is held by Crossref, outside our infrastructure, and remains discoverable regardless of the state of our website.
• Linked updates — corrections and retractions are registered against the DOI, so the status of the version of record travels with its identifier (see Corrections & Retractions).

Self-archiving rights — a preservation layer in themselves

Because Lumora publishes under CC BY 4.0 with authors retaining copyright, authors may deposit all versions of their work — the submitted version (preprint), the accepted manuscript (postprint), and the published version of record — in institutional repositories, subject repositories, preprint servers, funder platforms, and personal websites, immediately and with no embargo. No permission from Lumora is required.

• We positively encourage deposit of the published PDF in institutional repositories: every additional trustworthy copy strengthens the preservation of the scholarly record.
• Deposited copies should cite the version of record and include its DOI link.
• These rights are guaranteed by the article's open licence and cannot be revoked. See our Open Access Policy and Copyright & Licensing Policy.

Format migration

File formats age. Lumora commits to keeping published content usable as technology changes:

• Articles are produced in widely adopted, standards-based formats (PDF and HTML with structured metadata) chosen for their longevity.
• If a format used for published content risks obsolescence, Lumora will migrate the content to a suitable successor format, preserving the intellectual content and presentation as faithfully as possible.
• Metadata follows community standards so it remains machine-readable by indexing and preservation services.

What is preserved

• The version of record of every article, including any correction, expression of concern, or retraction notice attached to it — retracted articles are preserved with their retraction marking, never deleted.
• Supplementary files published with the article.
• Journal-level and article-level metadata.

For underlying research data, we recommend deposit in dedicated data repositories with their own preservation guarantees, as described in our Data Availability Policy.

If a journal ceases publication

Should a Lumora journal cease publication, its published content will remain accessible: the archive will stay online, DOIs will continue to resolve, and — once preservation-network enrolment is in place — the dark-archive copy provides an independent guarantee. Ceasing publication never means removing the record. This is consistent with the preservation expectations of DOAJ and the transparency principles of COPE.
