The French National 3D Data Repository (aka CND3D) is an intitutionnal repository to preserve 3D data produced in Digital Humanities Research.
It is supported by the French Infrastructure Huma-Num for the safe and secure storage part of the tool.
The CND3D tool is used to make deposits of 3D objects but also to discover them in the advanced search module and visualize them in 3D online.


  • Creation of deposit with its metadata
  • Creation of 3D object information with metadata inside a deposit
  • Online Enrichment of 3D object metadata with interoperable thesaurus tag of PACTOLS' frantiq
  • DOI assignement on each deposit
  • DOI assignement on each 3D object
  • 3D object visualization with potree or 3DHOP
  • Creation of collection of 3D objects with reusable url for example La technothèque
  • Cross referencement of 3D objects or deposit with any HAL publication
  • Advanced search in objects or deposits with shareable links

User Experiences[edit]

Nearly 40 depositing entities had been registred in the CND3D.
More than 400 deposits are stored in the CND3D containing 1400 3D objects in 2022.
Massive deposits are made using aLTAG3D packages
Some users prefer to make deposits with the web interface
Almost 2To of data are stored in the CND3D. More than 10TB of additional data have been requested in the last 2 years.
