 JupyterHub	explore	file	The `Dataverse-to-JupyterHub Data Transfer Connector <https://forgemia.inra.fr/dipso/eosc-pillar/dataverse-jupyterhub-connector>`_ is a tool that simplifies the transfer of data between Dataverse repositories and the cloud-based platform JupyterHub. It is designed for researchers, scientists, and data analysts, facilitating collaboration on projects by seamlessly moving datasets and files. The tool is a lightweight client-side web application built using React and relies on the Dataverse External Tool feature, allowing for easy deployment on modern integration systems. Currently optimized for small to medium-sized files, future plans include extending support for larger files and signed Dataverse endpoints. For more details, you can refer to the external tool manifest: https://forgemia.inra.fr/dipso/eosc-pillar/dataverse-jupyterhub-connector/-/blob/master/externalTools.json
