How Milan's Digital Archive Crisis Reached Breaking Point: The Story Behind the Duplicate Image Replacement Push

Milan's major public cultural institutions are embarking on a coordinated effort to replace duplicate and degraded images across their shared digital collections, a housekeeping crisis years in the making that now threatens to undermine the city's ambitions as a global capital of design and visual culture ahead of the Milan-Cortina 2026 Winter Olympics spotlight.

The problem is not new. Throughout the 2010s, institutions from the Pinacoteca di Brera on Via Brera to the Museo del Novecento in Piazza del Duomo each ran independent digitisation campaigns, often scanning the same works multiple times using incompatible file standards and metadata schemas. The result: overlapping, mismatched, and in many cases technically inferior image records sitting simultaneously in the same public-facing portals.

A Decade of Parallel Digitisation, Competing Standards

The root of the problem lies in how digitisation funding arrived in Milan — in waves, institution by institution, rather than through a single coordinated municipal framework. When the European Union's Horizon 2020 programme pushed cultural digitisation grants between 2014 and 2020, individual institutions applied separately. Comune di Milano's own digital infrastructure arm, Milano Digitale, was not yet resourced to act as a central aggregator. Each institution used its preferred vendor, its own file-naming conventions, and its own choice between TIFF, JPEG2000, and lower-grade JPEG formats.

By the time the Lombardy regional government and the Comune di Milano began seriously discussing a unified digital collections strategy in 2022, internal audits at several institutions had already flagged duplication rates of concern. Palazzo Reale, which sits steps from the Duomo on Piazza del Duomo, reportedly discovered multiple instances of the same exhibition photographs catalogued under different accession numbers across two separate content management systems — a legacy of a rushed 2018 migration project.

The situation worsened as Milan's international profile intensified. The city's role as host of major Design Week events at the Salone del Mobile, held annually at Fiera Milano in Rho, has accelerated demand from international publishers, licensing agencies, and documentary filmmakers for high-resolution, rights-cleared imagery. When those requests hit the public portals and returned duplicated or degraded files, the reputational cost landed quietly but consistently.

The Cleanup Campaign and What Prompted It Now

The immediate trigger for the current replacement initiative was a January 2026 review conducted in preparation for Winter Olympics-related cultural programming. With international media attention set to descend on the city from February through March 2026, and with cultural institutions expected to feed image assets to accredited press portals, the duplication problem could no longer be deferred.

Milano Digitale, working alongside the Soprintendenza Archeologia, Belle Arti e Paesaggio per la Città Metropolitana di Milano, began a structured audit in February 2026. The audit targeted three priority collections: the Brera Art Library's photographic holdings, the civic photographic archive at the Castello Sforzesco, and the design documentation repository maintained in partnership with the Politecnico di Milano's DESIGN department in the Bovisa neighbourhood.

The process involves more than simple deletion. Each flagged duplicate must be assessed for whether either version holds unique metadata, annotations, or licensing information not present in the other. Where a higher-quality master file exists in offline storage — as is frequently the case at the Castello Sforzesco, where a dedicated digitisation lab has operated since 2019 — technicians are pulling and processing those files to replace the degraded public-facing versions.

For institutions and researchers working with these collections, the practical advice is consistent: treat any image downloaded before March 2026 from Lombardy's shared cultural portal as potentially superseded. Cross-reference against the updated accession records, which institutions are publishing incrementally through the summer. The Pinacoteca di Brera is expected to complete its updated image set by September 2026, ahead of the autumn exhibition season that draws collectors and press from across Europe to Via Brera and the surrounding Brera Design District.

The cleanup will not fix the structural problem on its own. Without a binding common standard for future digitisation contracts — something Milano Digitale has been developing but not yet formally adopted — the same fragmentation risks recurring the next time a major funding cycle arrives and institutions again move at different speeds.
