View source for Workflow:How to preserve your 3D data with the French National 3D Repository?

==Context==
The concepts of ''archiving'' and ''preservation'' of digital data should not be confused. Preservation implies that data is stored and populated with a set of metadata on a medium. Archiving brings an additional constraint: as file formats evolve, the files must also be updated to ensure the long-term readability of the content. This costly operation can only be done if the file format is documented and has a [https://facile.cines.fr/ validator]. As a consequence, only a few file formats can be accepted. Preservation, on the other hand, means keeping the files as they were received, without maintaining the file formats, which is a lighter solution. Although there is no obligation concerning the file formats that can be deposited, we can only recommend that the most universal possible formats be used, which are documented and can be opened with software that is accessible in the medium term.

Preserving files does not only mean putting them on a server or a hard disk, as several dangers can arise. Over time, one can forget that they exist. Then, one can also forget how they were produced, for what purpose. This is important information that allows you to have confidence in the data: this is a key aspect in the reuse of data for scientific research. All this information should be transcribed in the form of metadata. The main advantage of the proposed workflow (compared to archiving) is to format the information so that it can be recognized by the tools developed by the [https://3d.humanities.science/ French National 3D Data Repository (aka "Conservatoire National des Données 3D / CND3D")] and several other search engines ([https://isidore.science/ Isidore], [https://ariadne-infrastructure.eu/ ARIADNE+] and [https://www.gotriple.eu/ GoTriple]) when it will be in place. Thus, from a single point of deposit, data can be retrieved on other platforms.
