A little bird told me[1] that integration between RSpace (an electronic lab notebook) and Dataverse has reached "advanced prototype stage" so I just tried it out and it works! Here's what I did.
Create an account at
https://community.researchspace.com and find Dataverse under "Apps"

Click "Add Dataverse", fill in your the URL of your Dataverse installation (I used
https://demo.dataverse.org ), your Dataverse API Token[2], and your dataverse alias ("pdurbin" for me to correspond to
https://demo.dataverse.org/dataverse/pdurbin ). Then you can click "Test".

Then, you go to "Workspace" and click "Export".
