Dear Jana,
at KU Leuven we have developed an application for synchronizing files from different source repositories into a Dataverse installation.
In addition to iRODS the application also has plugins for the following systems:GitHub, GitLab , Dataverse (use other Dataverse as source to import the data),Microsoft OneDrive, Microsoft SharePoint Online, OSF, SFTP, REDCap.
We are also working on a tool to be able to push data from iRODS to a Dataverse (initiating it from iRODS).
I hope this helps,
Best regards,
Ingrid
