I need to add schema to a specific topic on forum. It’s a directory page that would benefit from schema specifically for the data on the page. Could someone point me in the right direction. All I have really seen is that you have to override show.html.erb - but I haven’t found anything else about the validity of that or how to do it. I appreciate the assistance!

I’m bumping this to see if someone else might see it who would have some ideas. This is specifically referring to Published Pages pages that we have created. Thanks for any help you might offer.
