Since July 2016 I have been working as Associate Application Systems in the Teaching and Learning Applications group at Columbia University. I have developed several apps, including this Photo Roster, an LTI plugin to the Canvas Learning Management System.
This is the third generation of the Photo Roster tool at Columbia. The first generation, for the Prometheus LMS, was famously scraped by Mark Zuckerberg when he extended Facebook to Columbia. To prevent future release of private student information, this version uses SAML and OAuth2 to authenticate users and securely retrieve student information from the Canvas API, and Oracle SQL to store and retrieve the photo authorizations.
It would be a release of private student information if I showed you the Roster live, so I created a demo class with famous Columbia alumni, and used a screen recorder to make this demo video. Enjoy!
