Hi Joel!

This is from Rating Manager. You can disable Rich Snippets from the settings panel in Rating Manager > Settings and see for “Structured data”. We use http://schema.org/Review for better SEO. More information is here: https://developers.google.com/structured-data/rich-snippets/reviews#reviews

I don’t think you need to edit the schema. It’s integrated to work nicely with Rating Manager. If you really need to edit it, then try to use a filter: elm_ur_html_template . Related file is: rating-manager.class.php , but I don’t recommend to edit directly.
