Custom Post Type Relationships

This talk discusses ways to relate post types to each other in WordPress: Actors starring in Movies, Speakers giving Talks, Groups hosting Events located at Venues. It covers how to store such relationships in the WordPress database and how to modify the WordPress interface to allow them to be created. This page contains a link to the presentation on SlideShare, plus links to download the code I wrote during the presentation and to other resources I mentioned. (I presented this talk at WordCamp Orlando 2012 on December 1.)
