RM 1.1 Multiple ratings for a resource?


I am currently using the resource manager as a way to rate and review certain prescription drugs.

Currently there is only 1 overall rating, but is it possible to have more than 1 rating?

For example Effectiveness rating, Safety rating, Would recommend to a friend rating?

And then be able to sort on these such that people can see the most effective drugs, safest drugs, etc.

Any idea on how to achieve this?
