Review Comment:
Hi @Claudenw,
We have a mix of using constants and expressions to define this map. I think
it would be better to do it one way or another: Use all constants or use all
expressions.
The simplest would be to inline the constants from `Converter` and decrease
the new public footprint. Alternatively, to keep constants we could make them
package-private in a new or existing class.
Any thoughts on this?
