in the output schema but is not present in the input data/schema, then the

Many in the community are using (and asking for) the user-friendly name to
be in .displayName() and a machine-friendly name like
'convert-record-record-reader' in the .name() property.
> Add Processor capable of converting between different "record formats" with
> the same schema
