科斯莫·韦恩曼讲述了他为获取罗丹博物馆已受资助创作的公有领域雕塑三维扫描文件而进行的八年法国信息自由斗争。法国行政文件获取委员会(CADA)认定,这些由公共资金创建的扫描文件属于行政文件。但自2019年提起诉讼后,巴黎行政法院基本支持了韦恩曼的诉求,并命令博物馆提供多种格式的文件。韦恩曼称,博物馆和文化部无视了该判决。 在二审中,法国最高行政法院认定,这些扫描文件不属于行政文件,而是罗丹博物馆不可处分馆藏的一部分,可与实体复制品相提并论。法院驳回上诉,判令博物馆支付3000欧元诉讼费用,从而实际上推翻了下级法院此前对韦恩曼有利的裁决。 此案凸显了一个核心的文化获取问题:由公共资金创建、且作品本身已进入公有领域的扫描文件,是否应可自由获取和再利用,包括用于商业用途?韦恩曼警告说,保密、诉讼和对机构权威的顺从,可能使信息透明法律形同虚设。他将于2026年10月13日在COMMUNIA举办的“罗丹案”沙龙活动上讨论这些问题。

The Hacker News 上的讨论主要围绕 Cosmo Wenman 与罗丹博物馆之间关于雕塑高精度三维扫描件的争议。法国国务委员会拒绝公开这些扫描件,将其视为博物馆不可处分馆藏中的实体艺术品,而非可以公开的行政文件。Wenman 则认为,这些扫描件由公共资金资助,博物馆也曾承诺在网上公开,因此依据法国信息自由法,它们属于公共文件。 评论者对博物馆的动机意见不一。有人怀疑博物馆是在保护复制品销售、维持机构对艺术资源的把控,或担心高精度的数字复制品会削弱原作的权威性。另一些人则强调文物保护、来源记录,以及实体艺术品无法被扫描件取代的观点。 另一场争议涉及如何界定罗丹遗产。法国法律承认最多十二件经授权、在罗丹去世后制作的青铜复制品为“原作”,而许多扫描件所呈现的是石膏模型,它们通常被认为更接近罗丹亲手创作的作品。讨论者还指出世界各地已经存在大量复制品和较低精度的扫描件。 后续讨论认为,这项裁决在法律上颇为牵强,并批评了官僚机构的敌意态度;但也有人质疑文章是否公正呈现了博物馆的立场。之后的 lengthy? Long tangent: 一场冗长的题外讨论探讨了可编程法律或经过正式验证的法律能否减少司法腐败。

[Note: I will be speaking at COMMUNIA Salon: The Rodin Case, on October 13, 2026]

When France’s highest court for administrative justice hears your eight-year freedom of information case, and the court’s own legal analyst directly invokes surréalisme to argue that “sometimes a document is not a document,” you know you’re about to get wrecked.

In 2017, I began writing to the Rodin Museum requesting that it identify and grant public access to 3D scans of Auguste Rodin’s sculptures, some of the most well-known and widely copied public domain cultural heritage works in the world. The museum’s administrators responded with a sustained campaign of lies, weaponized incompetence, and open lawlessness.

When Paris-based civil rights advocate Alexis Fitzjean Ó Cobhthaigh took up my case and sent the museum a formal request for its 3D scans, its senior directors quietly sought legal analysis from the French government’s own Commission on Access to Administrative Documents (CADA). The CADA’s opinion was in my favor, finding that the museum’s scans were undoubtedly administrative documents and therefore must be made accessible to the public. The museum’s director did not dispute the CADA’s analysis, but she confided to the Ministry of Culture, in writing, that she planned to ignore French freedom of information (FOI) law and make me take her to court.

In 2019, we filed suit in the Administrative Tribunal of Paris, where open culture and digital rights advocacy organizations Communia, Wikimédia France, and La Quadrature du Net joined me as co-plaintiffs. We were all represented by Fitzjean Ó Cobhthaigh, who had advised us that while the facts and law were on our side, we still faced an uphill battle, since the judges would be extremely deferential to the Rodin Museum and would grant it the benefit of any doubts. He was certainly correct, but I did not anticipate that in both the Paris court and, later, on appeal in the Conseil d’État, the judges would not only tolerate the Rodin Museum lying but would reward them for it. I did not imagine that showing them how the museum had lied to them on multiple issues would have absolutely no effect on its credibility on other issues. I did not expect that the Conseil d’État itself would not only decline to hear our testimony and evidence but would take up the task of inventing and promoting new, nonsensical arguments and falsehoods the museum itself had never dared to raise.

During litigation in the Paris tribunal, the Rodin Museum baselessly insinuated that I was a would-be criminal counterfeiter while pleading its own technological illiteracy and failure to preserve the documents in its care. The museum claimed that even with the help of (unnamed) outside experts it couldn’t figure out how to use its own scan documents. It dissembled about which sculptures it had scanned and falsely asserted that its written applications for public funding to produce those scans were non-existent.

It is no exaggeration to say that the Rodin Museum lied outright to the Paris court about the few scans it reluctantly admitted to holding. It claimed that its ultra high-resolution, state-of-the-art laser-scanned 3D point cloud documents, which are in open plaintext formats that are routinely used in the digitization and cultural heritage fields, were so technologically mysterious, and of such poor quality and so incomplete as to be virtually impossible to even visualize, and were thus unusable even by the museum itself.

Images of the museum’s point cloud documents that I obtained from third parties illustrate the museum’s fraud on the public and the court:

Visualizations of the Rodin Museum’s point cloud scan documents of Le Penseur, La Porte de l'Enfer, Les Trois Ombres detail, and Le Baiser

The Rodin Museum’s funding applications, which we forced the ministry to disclose in a separate FOI procedure and presented in court, also made the museum’s lies and misappropriation of public funds perfectly clear.

Not content merely to tell simple, substantive lies, the Rodin Museum submitted increasingly absurd and disjointed legal briefs to the court. For example, it simultaneously claimed that its scans were unusable and that they could be used by counterfeiters. In one brief, the museum confirmed that it held a scan of Les Trois Ombres, then in the next brief denied the sculpture had ever been scanned. (We replied with a photograph of the museum’s subcontractors scanning the sculpture.)

The Rodin Museum argued that they should benefit from every possible exception to French FOI law, even if they were mutually exclusive and had no connection to the facts of the case. We refuted them all.

The Paris court rejected all of the museum’s arguments relating to trade secrecy, counterfeiting, its business model and revenue, and intellectual property. In December 2023, the court ruled that 3D scans in a variety of formats were administrative documents and therefore must be made available to the public. In a significant victory for open culture, the judges directly ordered the museum and ministry to give me those scans and to compensate me €1,500 for my trouble.

But the Rodin Museum and the Ministry of Culture simply ignored the court’s order. To be clear, they did not appeal it, they ignored it.

Worse, the Rodin Museum’s buffoonish hand-waving about 3D scan technology apparently confused or impressed the judges, who ignored our world-class expert’s testimony on point clouds. In their decision, the judges improvised a novel exception to French FOI law, ruling, without any discernable legal basis, that 3D scan point cloud documents in open, plaintext formats could be withheld from the public.

In late 2023, we appealed that point cloud exception in the Conseil d’État, France’s highest court for administrative justice, where representation by specialist avocats au Conseil d'Etat et à la Cour de cassation is mandatory. Represented by Fitzjean Ó Cobhthaigh’s colleagues at the law firm SCP Marlange - de La Burgade, we detailed the lower court’s serious procedural and legal errors and its obvious misunderstanding of point cloud documents.

We presented testimony from experts in academia and industry and the arts.

We showed the high court that cultural heritage programs the world over routinely use and publish point cloud documents that the Rodin Museum claimed were unusable, and that the French government publishes petabytes of open source point cloud documents from its aerial 3D scan surveys of the entire French territory.

Our appeal explained to the court how point cloud documents are produced, and showed that the French government itself had spearheaded the development of free, open source software for viewing and using them.

We referred the court to the Ministry of Culture’s own published guidance on the proper formatting, use, and accessibility of open format point cloud documents in the cultural heritage sector.

None of this mattered.

In its reply to our appeal, the Rodin Museum reiterated to the high court its fantastical lie that point cloud documents are fundamentally unintelligible, citing as its sole authority the speculative musings of the lower court’s rapporteur public (the court’s own legal analyst).

The rest of the Rodin Museum’s briefs in the Conseil d’État were equally inept and detached from reality, so much so that we thought they might have been too stupid to warrant a response, and we seriously considered letting the case proceed to a decision without replying. But we felt a duty to create a record that repudiated the museum’s claims point-by-point to convince the judges of the absurdity of the museum’s misrepresentations. Also, we hoped to create the possibility that the high court judges might feel embarrassed to credit the museum's nonsense.

It didn’t work.

In the days leading up to our hearing, the high court sent us a short notice that it was, on its own initiative, raising an entirely new argument on the museum’s behalf, on which it was likely to decide the case, an argument the museum itself had not suggested: that point cloud documents were not even administrative documents.

We submitted a reply, but we could only guess at what we were rebutting since, in its wisdom, the court had not disclosed the basis of its new argument. We reiterated that the Rodin Museum’s publicly funded scans had clearly been made within the context of its public service mission, and that by all legal standards, precedents, and CADA analyses, they were clearly administrative documents. And we reminded the court of the well-established, conventional nature of point cloud documents.

At our hearing in early December, 2025, the high court’s rapporteure publique began her presentation by reminding the judges of René Magritte’s surrealist painting The Treachery of Images (This is Not a Pipe), and explained that “sometimes a document is not a document.”

For additional dramatic effect she then read aloud the definition of “document” from the Dictionnaire de l’Académie française, then stumbled over her words when she seemed to realize it very clearly argued against her position. She asserted and continuously reiterated that point cloud documents are neither documents nor administrative documents. She offered her own assessment, too ludicrous for the museum to have suggested, that it would be too burdensome for the museum to deliver copies of its point cloud documents to me—documents it had already gathered and been sitting on for eight years. The rapporteure publique recited a variety of supposed exceptions to FOI law that did not fit the facts of the case and had already been examined and rejected by both the CADA and the lower court, and were not even subjects of the appeal. These included moral rights, trade secrecy, commercial reuse, counterfeiting, and economic competition, for example, the last of which drew approving nods from the judges. It was as if by merely naming these, without any evidence, relevance, or reasoning, she was presenting the judges with a buffet of options from which they could choose to reject our appeal.

In our opportunity to briefly respond with oral arguments, we directed the court’s attention to the example point cloud document we had submitted that morning: if anyone cared to look at it, it would demonstrate that it was, in fact, a document. We could have also quickly drafted and submitted a follow up written brief immediately after the hearing, but that seemed pointless. We had already said everything that could have possibly been said.

Our entire eight-year effort up to that point had generated argumentation, replies, testimony, correspondence, imagery, and hard-won evidence, which the court had compiled into a dossier more than 800 pages long. The public is not permitted to read that dossier, and in light of the way it handled our case, it appears that no one at the Conseil d’État has read it either.

The Conseil d’État issued its written decision a few weeks after the hearing, and it went well beyond what its rapporteure publique had suggested. It ruled that the Rodin Museum’s 3D scans of cultural heritage works are legally indistinguishable from physical reproductions. The museum’s scans are not administrative documents but part of its inalienable collection, and French FOI law is therefore inapplicable.

By implication, the high court’s ruling means that the government’s own FOI experts at the CADA had repeatedly erred in their analyses in my favor, as had the Paris court. Our earlier victory on other 3D scan formats was effectively undone. There would be no need for the Rodin Museum and Ministry of Culture to heed the lower court’s order that they had already chosen to violate.

The Conseil d’État judges noted that since FOI law did not apply, there was no need to consider the facts or circumstances of the case.

The judges threw out our appeal, ordered me to pay €3,000 to the Rodin Museum, and did not even bother to send me written notice of their decision.

While I’m disappointed in the court’s decision, I am proud of our work, and I appreciate how the case resolving this way achieves a strange sort of perfection.

We had begun this project by asking for permission to access publicly funded digitizations of public domain cultural heritage works, then asserting our rights to them, and methodically following every rule and procedure and official channel, and relying on the law and the truth. Confronting the Rodin Museum and Ministry of Culture with these, despite a multi-billion euro resource disadvantage, we forced them to explain and defend their policies, reasoning, and outlook, and they could not do it.

Like the Rodin Museum, other arms of the Ministry of Culture talk a good game about digitization and accessibility, but refuse to deliver. French FOI law looks good in principle, but in practice it can easily be abused by a hostile and lawless administration to exhaust petitioners’ resources and create indefinite delays until, in the final hour, a deus ex machina intervention delivers the outcome it wants.

In this case, that outcome is for the preservation, dissemination, and benefits of digitization of France’s cultural heritage to be entrusted to the care of unaccountable administrators who prize secrecy and exclusivity over accessibility, who lie without shame, who are shielded by the law but unconstrained by it, who forgo even the appearance of adhering to its procedures and orders, and who don’t hesitate to shift from proclaiming their authority to pleading their incompetence and illiteracy whenever it suits them.

The court has upheld this tableau surréaliste, but no one can justify it.

On 13 October, 14:00 to 15:00 CEST, join us for a new COMMUNIA Salon exploring the French “Rodin case” and a deceptively simple question at the heart of access to cultural heritage: Should 3D scans of works in the Public Domain be freely available for reuse, including for commercial purposes?

During this COMMUNIA Salon, we will unpack the legal twists and turns of the Rodin case and discuss what the decision means for the Public Domain, cultural heritage institutions and the people who want to access and reuse our shared cultural heritage.

Cosmo Wenman, Alexis Fitzjean ó Cobhthaigh, Benjamin Jean (INNO3) and Brigitte Vézina (Creative Commons) will discuss the case, with COMMUNIA member Camille Françoise moderating.
