Hi Audrey,
The easiest implementation of multiple sessions is if your participants have some kind of id. For example, in Prolific, each participant knows their Prolific ID and you can ask them to enter that ID at the beginning of each session. We have an example for a study from Prolific
here.
So, if your participants have their own id, they can enter that in a questionnaire very similar to the
Prolific ID questionnaire that starts our Prolific example.
I should note that we are working one on a new version for integrating our Minno library with DataPipe. In that version, we will provide support for adding variables to the URL and recording them with the data. For example, if you redirect participants from Qualtrics to our system and you know the participant's ID, you can write code in Qualtrics that will redirect the participants to your Minno study and add the ID to the URL. For example: "
https://baranan.github.io/minno-tasks/studies/datapipe.example.iat/exampleiat.html?qID=xyz"
I hope we release this version in a couple of days.
All the best,
Yoav
