Digital 3D Objects in Art and Humanities: challenges of creation, interoperability and preservation. White paper

International audience; With this White Paper, which gathers contributions from more than 25 experts of 3D imaging, modellng and processing, as well as professionals concerned with the interoperability and sustainability of research data, the PARTHENOS project aims at laying the foundations of a comprehensive environment centered on the researchers' practices concerning 3D digital objects.The topics addressed in the document are meant to help to ensure the development of standardized good practices relating to the production, the handling, the long-term conservation and the reuse of 3D objects. Therefore, even if the focus is put on technical questions (formats, processing, and annotation), the White Paper also identifies the need to clarify the legal status of 3D objects, in order to facilitate their reuse(s) in non-research contexts, in particular in Museums.
