How to Build the European Standard of Sovereignty and Continuity Required by the Art World?

Artistic Heritage: The Challenge of Digital Sovereignty

The digital transformation of the art market has reached a decisive milestone with the accelerated digitisation of Catalogues Raisonnés. This shift meets major operational and security imperatives. Digital archiving speeds up data structuring, ensures traceability, and enables real-time updates to attributions and provenances. Beyond greatly simplifying information sharing and retrieval, digital tools also streamline print publishing workflows. In the short term, digitising the entirety of these definitive reference works appears inevitable.

However, this transition brings to the fore the critical question of the long-term sustainability and security of chosen technical infrastructures. Selecting a software solution cannot be reduced to adopting a simple database management system or a generic archiving platform. The scientific rigour inherent to compiling a Catalogue Raisonné requires highly specialized domain-specific functionalities absent from generalist Anglo-American collection management software. Where a basic database treats an artwork record as static, a dedicated tool must map out the complexity of states and impressions, chain-of-ownership lineages, cross-indexed exhibitions and bibliographies, as well as the scholarly evolution of attributions.

The second strategic imperative lies in data sovereignty and the legal framework governing host environments. Infrastructures dependent on American providers subject to extraterritorial laws—such as the CLOUD Act—expose data stored with AWS, Google Cloud, or Microsoft Azure to administrative seizures by the United States government. Compounding this risk is the unconsented scraping of content by artificial intelligence models trained by these tech giants. Securing the confidentiality of unpublished scholarly research necessitates exclusively European hosting.

For archivists, art historians, and foundations, durability hinges on fundamental institutional and technological guarantees—essential to preserving heritage across decades. Long-term integrity relies first on a stable, seasoned management structure capable of steering academic projects with the consistency that art history demands. This governance must be backed by a resilient financial backbone, untethered from the pressures of investment funds driven by speculative, short-term demands often incompatible with the extended timelines of academic research. Technically, sustainability requires an open, independent, and highly secure architecture. Such design guarantees institutions complete data reversibility, allowing them to export or retrieve their entire holdings directly, seamlessly, and without vendor lock-in.

Ultimately, the software vendor’s financial viability and structural stability dictate service continuity and archival integrity over time. Given such stringent specifications, the market offering remains exceptionally narrow.

To meet these exacting standards, the French platform InventoZen combines the power of an intuitive interface with tailored support, progressively establishing itself as the benchmark provider. Within two years of operation, the company has brought together over 200 published or active Catalogues Raisonnés, sustaining uninterrupted growth that represents an unprecedented volume on an international scale. The vendor stands today as the sole player guaranteeing end-to-end hosting within European borders. According to its president, Diane de Polignac, several major artist foundations have now selected this infrastructure.

The emergence of a French and European leader in this critical tech segment sends a strong signal for the protection of global cultural heritage. By pairing scientific expertise with digital sovereignty, Paris and the broader European ecosystem reaffirm their central role in safeguarding and transmitting artistic creation.
