This paper presents an update of the French solution for long-term archiving combined with online publication of 3D research data in the humanities. The choice of data organisation, metadata, standards and infrastructure is in line with the FAIR principles of the semantic web. Since 2017, our consortium 3D for Humanities offers this service through the French National 3D Data Repository for Humanities. This was the start of our collaboration with CINES (Centre Informatique National de l'Enseignement Supérieur), the standard Open Archival Information System (OAIS) infrastructure for research data in France. In 2021, with more than one thousand (1000) projects registered, driven by laboratories from all over the country, open questions were posed to the community. In response, we have developed a new metadata schema that allows a more precise description of the research content, greater openness to other non-archaeological humanities fields, and better FAIR compliance. This metadata schema is aligned with standard vocabularies and mapped to the Europeana Data Model (EDM). Among other online features, a 3D viewer has been implemented to meet the needs of researchers and public communication. As designed, aLTAG3D, the desktop UI software we developed to help research labs create Submission Information Packages (SIPs), has adapted itself to the new schema through the XSD content.
