First, create a list of profiles to query. This could be a custom list, all authors of the submissions, all members of a group, such as reviewers, etc. This should be a list of profile IDs or emails that are associated with profiles.
Check your work: The result should be a dictionary with the query profile ID and the OpenReview Profile Object.
3. Parse the profiles
Review the example here to understand how profile information is stored, and one example of how to flatten and tabulate the data.
Check your work: Use Python to get the profile ID property, the preferred email, and the current institutional affiliation. Then print the profile information and check that the data you extracted is correct.
