Preserving 3D digital objects
The long-term preservation of 3D digital objects raises some critical issues. Indeed, firstly, different kind of data can be archived: the original files depending on the method used to digitize; the final version, depending on the goal (simple acquisition or modelisation) and any relevant information (text, images, pdf , scenarios ...) added for a better comprehension of the 3D object.
Secondly it is important that metadata accompany the archive to ensure that the 3D object will be human-readable in the long-term. These metadata have to be completed in distinct files.
The 3D consortium of Huma-Num developed a tool, aLTAG3D to easily produce metadata file for the full 3D archive. Lastly, a place to preserve 3D data in the long term has to be found. Many solutions exist, depending on the countries. In France, there are solutions such as the 3D conservatory for 3D data research for mid-term preservation, and the CINES in the continuity for long-term preservation.
Workflow steps(4)
1 Convert to 3D long-term format
2 Describe and annotate
3 Create an archiving packet with 3D data and metadata
4 Upload the archive in an official reliable repository
The SSH Open Marketplace is maintained and will be further developed by three European Research Infrastructures - DARIAH, CLARIN and CESSDA - and their national partners. It was developed as part of the "Social Sciences and Humanities Open Cloud" SSHOC project, European Union's Horizon 2020 project call H2020-INFRAEOSC-04-2018, grant agreement #823782.
