Hong Kong's Digital Archives Push Hits Snag Over Duplicate Image Replacement Standards

Three of Hong Kong's largest cultural institutions are at odds this week over how to handle duplicate image replacement in shared digital archive systems, a dispute that has temporarily suspended cross-platform uploads and left thousands of newly scanned files in a processing queue. The standoff involves the Hong Kong Public Libraries network, the Hong Kong Film Archive in Sai Wan Ho, and the digitisation unit operating under the West Kowloon Cultural District Authority.

The timing is awkward. Hong Kong has spent the past two years accelerating its digital heritage programmes, partly to shore up its credentials as a regional cultural hub against competition from Singapore's National Library Board, which completed a major metadata standardisation overhaul in early 2025. The city's own Digital Culture Strategy, a framework document published by the Culture, Sports and Tourism Bureau in November 2024, set a target of having 1.2 million archival assets searchable online by the end of 2026. That deadline is now looking precarious.

What Sparked the Dispute

The immediate trigger was a software update pushed on June 30 to the Joint Repository System — the shared backend that links the three institutions' collections. The update introduced an automated duplicate-detection algorithm that flags images appearing more than once across collections. Where it finds a match, it prompts archivists to designate one file as the canonical version and replace or suppress the others. Staff at the Film Archive's repository desk in Sai Wan Ho flagged concerns on July 1 that the algorithm was misidentifying near-identical but legally distinct images — for instance, separate prints of the same film frame held under different licensing agreements — as duplicates eligible for deletion. Deleting the wrong file could mean losing provenance metadata that took months to compile.

The Hong Kong Public Libraries' Central Library on Queensway escalated the matter to bureau level by July 2, requesting a freeze on automated replacements until a manual-review protocol could be agreed. The West Kowloon Cultural District Authority, which manages the largest share of newly digitised contemporary art documentation, backed the freeze. As of Friday morning, no new batch uploads had been processed for four days.

The episode exposes a gap that archivists have flagged repeatedly: the Joint Repository System was built under a 2021 contract worth approximately HK$38 million, but its specifications predated the current scale of cross-institutional sharing. The system was not designed to adjudicate ownership disputes between participating bodies when two institutions both hold rights to what the algorithm treats as a single image.

Practical Fallout and Next Steps

For researchers, the freeze has real consequences. The University of Hong Kong Libraries' special collections team, which relies on the shared system for academic access to pre-1997 newspaper photography, told staff this week that reference requests involving digitised images may take up to three additional working days to fulfil while the queue clears. The Hong Kong Baptist University's Visual Studies programme had a batch of 4,000 scanned images from a private donation due to go live on July 7; that launch is now postponed.

A working group involving technical leads from all three institutions is scheduled to meet at the West Kowloon Cultural District's M+ administration building on July 8. The group is expected to draft interim manual-review guidelines that would allow non-contested files — those held exclusively by one institution — to resume processing while disputed duplicates are reviewed case by case.

Archivists familiar with similar disputes point to London's Wellcome Collection, which resolved a comparable duplicate-replacement controversy in 2023 by publishing a clear hierarchy of file authority: the originating institution's version is always canonical unless a rights transfer document exists. Hong Kong's institutions have not yet adopted an equivalent rule, and negotiating one across bodies with different governance structures — one government department, one statutory authority, one cultural district corporation — is not straightforward.

Institutions with pending digitisation grants should document their image provenance records now, before any resumed automated processing touches their files. The Culture, Sports and Tourism Bureau has not yet publicly addressed the freeze, but the July 8 meeting will be the clearest signal of whether the 2026 deadline for 1.2 million searchable assets remains viable.
