Ability to dump the mapping between names in logical model and target schema

[bartkl]

It might be nice to be able to pass a flag like --dump-name-mapping which writes the mapping from the names in the logical information model (URIs) to the schema (record and field names, etc.). This way, some name transformations which are obscure or ambiguous can still be related to their source.

The output would probably be JSON text, written to stdout or a file.

It's important to think through whether this is a good idea. Perhaps this desire is indicative of bad design, i.e. you should not have to deal with this problem perhaps? I'm reminded of Joeps preference to have 1:1 name mappings (but of course it's never truly 1:1, since many schemas won't support URIs as names because of their length of contained characters).

       --[no-]mapping                                     Dump mapping between input and output schema to console.

Even better might be to have the possibility of an image representing the transformation. This is certainly a lot more difficult, but Malli's DOT and PlantUML functionality might help sufficiently here.
