Thank you, Mark! I had read about the "elements" before posting this question but I didn't understand what it means before reading your explanation. This is very useful information, many thanks!
As an admin, I'll upload the information to be used in the certificates. I am very comfortable with Moodle's import/export functions for users, grade book, database activity, etc. That's why that was the first thing I could think of.
Thanks for giving me a direction.
