| − | + | There are two ways to create a repository on the CND3D - the final objective being to keep the data on the servers of the National 3D Data Conservatory. | |
| − | + | * Either the files are loaded directly from the web browser, and all the metadata must then be filled online. This approach is not recommended for large projects with numerous data. (need for Sarah's confirmation). | |
| − | + | * Or the files are filled in through the aLTAG3D software - to be installed on the computer. The files are loaded into the software and a large part of the metadata is then retrieved automatically: only the descriptive metadata remains to be documented. Once all the information is filled in, aLTAG3D checks the validity of the deposit, and generates a tree structure with the metadata (xml file). This package can be sent via ftp, with Filezilla for example. This second option is therefore preferable because it allows better documentation of the repositories. Furthermore, when the file formats are recognized by the archiving infrastructure CINES, the same SIP can be deposited here. | |

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. | The concepts of ''archiving'' and ''preservation'' of digital data should not be confused.

| − | 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.

Thus, from a single point of deposit, data can be retrieved on other platforms. |
