It is possible to builtin or standard technique for Apache Camel's Bindy data format to marshal to/from java.util.Maps? From what I will tell, the process are only able to be annotated into POJOs so that certain Bean qualities map to/from CSV fields.

Camel's CSV data format supports marshaling to/from Maps (whose secrets correspond with CSV headers and values correspond with CSV fields). Regrettably, it is dependent on Apache Commons CSV, that is still incubating and not active and mature enough to become reliable.

No. Bindy is perfect for binding to/from java beans.

You should use other components that maps to Map structures, for example camel-csv, camel-flatpack.
