  We introduce the French National 3D Data Repository for Humanities designed
for the conservation and the publication of 3D research data in the field of
Humanities and Social Sciences. We present the choices made for the data
organization, metadata, standards and infrastructure towards a FAIR service.
With 437 references at the time of the writing, we have feedback on some
challenges to develop such a service and to make it widely used. This leads to
open questions and future developments.
