I have an idea to my community and for a plugin but I’m starting as “discourse plugin developer” and there are too many things to learn yet.

I hope you can help me to see the best way to address my idea. Here we go:

* * *

Let’s say we have a **Topic** called “Review about the new Ford Fusion 2017”, with a normal text and some “fixed” metadata with a rating like:

- Price: 6/10
- Engine: 9/10
- Confort: 8/10
- CO2: 5/10

Then, the community can **Reply** the **Topic** with the same approach: normal text with its comments and fill the same metadata:

- Price: 2/10
- Engine: 4/10
- Confort: 6/10
- CO2: 6/10

At the end, I want to display at the top of the topic the average.

* * *

I hope I explained well, if not I can do a mockup with the feature that I want to create.

Any ideas?

Thank you!
