This is a prototype digital library application based on the YouTube Data API version 2 and written in PHP by Jason A. Clark (@jaclark). A full article explaining the theory and how-to behind the app is published in the Code4Lib Journal, Issue 20 - http://journal.code4lib.org/ titled "Developing a Digital Video Library with the YouTube Data API".
Example scope note for live app in production:
