Milan's Digital Archive Crisis: The Key Decisions Ahead on Duplicate Image Replacement

Milan's major public collections are sitting on a problem that has been building quietly for years: tens of thousands of duplicate digital images scattered across institutional archives, from the Pinacoteca di Brera's cataloguing system to the civic photographic holdings at the Archivio Fotografico del Comune in Via Durini. The question of what replaces those duplicates — and who decides — has now become urgent, with Milan-Cortina 2026 Winter Olympic events bringing global press and cultural tourism to the city from February onward.

The timing matters because Lombardy's regional government and Sala's city administration have both committed, at least rhetorically, to a unified digital presentation of Milan's cultural assets. A fragmented back-end, where the same image of, say, the Galleria Vittorio Emanuele II interior exists in four different resolutions under three different rights classifications, makes that presentation nearly impossible to deliver cleanly. Cultural technology consultants working across Italian civic institutions describe the duplication problem as endemic to collections that were digitised in waves — first in the late 1990s, then again after 2010 when higher-resolution scanning became affordable — without a single controlled vocabulary or master asset register tying the runs together.

What the Institutions Are Weighing Right Now

The core decision facing institutions like the Museo del Novecento, which manages thousands of images of its permanent collection on Piazza del Duomo, is whether to pursue automated deduplication or human curatorial review. Automated tools — several of which are now offered by firms including Axiell and Zetcom, both active in the Italian market — can flag near-duplicate files by pixel hash comparison and metadata cross-referencing. They are fast. They are also, archivists will tell you privately, imperfect: an image of a Fontana canvas photographed in 1987 and again in 2019 after restoration is not, strictly speaking, a duplicate, even if a machine flags it as one.

Human review costs more and takes longer. For a collection of 80,000 images — a plausible scale for a mid-sized Milanese civic archive — a curatorial team working at standard pace would need roughly 14 months to review flagged pairs, far beyond the pre-Olympics window. The compromise most institutions are now seriously considering is a tiered approach: automated resolution and format deduplication for clear technical copies, with human escalation reserved for images where rights, date, or condition metadata diverge.

There is also the rights question, which is not trivial. Italian cultural heritage law under the Codice dei Beni Culturali establishes specific reproduction rights for publicly held works, and when an institution holds two versions of the same image under different licensing histories, deciding which one to keep as the master record carries legal weight. Choosing the wrong file as the canonical version could expose an institution to rights disputes with the original photographer or the commissioning body.

The Practical Calendar and What Comes After

For institutions tethered to the Olympic preparation timeline, the operational deadline is roughly October 2026 — enough lead time before February for updated digital assets to flow into press packages, tourism platforms, and the official Milan-Cortina cultural programme materials. That gives collections managers fewer than four months from today to make the foundational call on methodology.

The Fondazione Prada, which operates its own rigorous digital asset system across its Largo Isarco campus, is understood to have completed an internal deduplication exercise in 2024, making it something of a local reference point. Public institutions do not have the same resource base, and the gap shows.

What happens next is largely a budget conversation. Lombardy's regional culture directorate has signalled interest in co-funding digital infrastructure projects linked to the Olympics, but no specific allocation for archive remediation has been confirmed in public budget documents reviewed for this article. City officials at the Assessorato alla Cultura have the alternative option of phasing the work: prioritise the most publicly visible collections for clean-up now, and tackle deeper holdings through 2027 and 2028. That is the lower-risk political choice. Whether it produces a coherent digital cultural offer in time for the February press wave is a different question entirely.
