==Workflow Description==

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 (see [https://coptr.digipres.org/index.php/Workflow:Life_Cycle_of_3D_Data_for_Cultural_Heritage 3D data life cycle] ) 

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 Consortium "3D for Humanities" of [https://www.huma-num.fr/about-us/ Huma-Num] developed a tool, [https://altag3d.huma-num.fr/ 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 [https://3d.humanities.science/ 3D National Data Repository] for 3D data research for mid-term preservation, and the [https://www.cines.fr/en/ CINES] in the continuity for long-term preservation.

<!-- Describe your workflow here with an overview of the different steps or processes involved-->

==Purpose==
This workflow is a use case scenario designed to illustrate best pratices in the long term preservation of
3D digital objects with a final deposit at the CINES (National Computing Center for Higher Education), a
public institution supervised by the French ministry for Higher Education and Research which offers
services to the scientific community in the long term digital preservation.

Long term preservation of digital documents has three main objectives:

* Keep the document
* Make it accessible
* Preserve intelligibility

==Context==
The use case scenario for preserving 3D digital objects was produced by the team of the consortium “3D for Humanities” for [http://ssk.huma-num.fr/# (SSK) the Standardization Survival Kit (SSK)], a toolkit for Humanities developed within [https://www.parthenos-project.eu/ the PARTHENOS project] in order to stabilize knowledge on standards and good research practices, giving access to them in a meaningful way, by the mediation of research scenarios.


<!-- Describe what your workflow is for - i.e. what it is designed to achieve, what the organisational context of the workflow is, and what content it is designed to work with -->

==Evaluation/Review==
<!-- How effective was the workflow? Was it replaced with a better workflow? Did it work well with some content but not others? What is the current status of the workflow? Does it relate to another workflow already described on the wiki? Link, explain and elaborate -->
The workflow has been extensively tested since 2016 by members of the Consortium " 3D for Humanities", and is regularly improved. For any questions or suggestions, please contact contact@humanities.science
