That's awesome! We are happy to hear the dataset is useful to the community!
These are the guidelines for using the dataset right now before the official release at the conference:
The dataset's copyright code will be CC BY-NC-SA.
You may use the challenge dataset now as is and refer to the challenge website for now as the source (http://www.recsyschallenge.com/2022/
For publications at other conferences please use a placeholder reference for now and replace it with the proper reference when that becomes available for the camera-ready of your paper. In the unlikely event that the camera-ready deadline of your other conference is before the RecSys conference and you want to use the dataset let me know directly and I can make an "in print" reference for you.
