How to convert policy routing rules using "all" and "iif" to OpenWRT's UCI format?

Question

I would understand if it's possible, and if yes how, to convert the following rules to OpenWRT UCI format using the rule directive:

ip rule add to all table 111 pref 4
ip rule add from 10.0.0.1/24 lookup 113 pref 32768
ip rule add iif lo lookup 113 pref 32768
ip rule add from all lookup 112 pref 32769

I also have a default route to add to a specific table:

ip route add default via 10.0.0.1 dev br-lan table 113

I guess for this one I will have to use the route directive, I'm just not sure how and I will like to familiarise more with the OpenWRT UCI way of doing this.

I also want to learn this because I would like to improve the automation facility present in OpenWISP (an open source wifi controller).

Thanks in advance
