The French National 3D Data Repository (aka CND3D) is an intitutionnal repository to preserve 3D data produced in Digital Humanities Research.
The CND3D tool is used to make deposits of 3D objects.


  • Creation of déposit with metadata
  • Creation of 3D object information with metadata
  • Enrichment of 3D Object metadata with interoperable Thesaurus tag
  • DOIs assignement on each deposit and on each 3D object
  • Creation of collection of some 3D Objects
  • Cross referencement with HAL publication

It allows to publish 3D data thanks to a DOI.
It allows creation of collection of 3D objects with persistent link to be used in other sites.
3D Object can be enriched online.
Cross references are permitted with HAL publications.

User Experiences

Nearly 40 depositing entities had been registred in the CND3D.
More than 400 deposit are stored in the CND3D containing 1400 3D objects.

Massive deposits are made using aLTAG3D packages
Some user prefer to make deposit with the web interface
Almost 2To of data are stored in the 3D Data Repository, more than 10To have been requested for the last 2 years.
