Jake,
I am a publisher and I am trying to grant access to my course/textbooks materials to moodle users (for example in a different moodle deployment) as an external tool (publishing the course as LTI) , but I only want to give access to such material to those students who can validate that they purchased the book (for example via a unique code printed in the textbooks or actually, any other validation method would work, but the goal is to not grant free access to the external course to all people enrolled in the school's course, but rather to validate from my end that they made a purchase)... have you heard of a similar case or can you provide any ideas on what can be done? Maybe I need to develop something but what would be the direction of this development? (maybe it's not even possible, and maybe it would be better to use my own LMS as the source of the LTI access point so I can control who is actually validated, but then again, I hope the first scenario is possible)
Thanks,
Rodolfo
