How to Change the CreativeWork Microdata in Genesis to Book, Music, or Recipe

A Genesis framework developer wants to know: How do I change the “CreativeWork” microdata in Genesis to Book, Music, or Recipe? In this episode, Tonya talks about strategies to find where Genesis sets the microdata attribute and then how to change it to fit your needs.

You’ll learn:

1. Where Genesis sets the microdata itemtype in the code.
2. A strategy of dynamically setting its value based upon the selected custom field (post metadata).
