Should add Schema markup to my sites Business Directory?

[ColeBField]

I'm adding a Business Directory to my ecom site to show where the product can be purchased/used. Some listings are stores where you can purchase others are restaurants, bars and spas the product can be used. My question is should I add relevant Schema markup for each listing? My thoughts are yes but wanted feedback from the community.
Thanks

Hi Cole,

I'm not sure that adding schema to businesses that are not yours would directly benefit you, though it might benefit the stores in question. Can you explain what your goal is with this?
