New template

Hello there. I have your plugin and I’m really exciting about this. Also I need another template to send in a marketplace, different than google or facebook feeds. Do you have any development guides to do this? Can I do it in a different way?
For example I want to change the names of meta tags in exported xml from “title” to “name”. How can I do this? Or in another tag I want to have static value.
Thanks for your assistant!
John
