Question: alternative serialisation/deserialisation

[skinkie]

This project is about (de)serialisation of XML and some other formats into dataclasses. Given that the deserialisation into dataclasses requires some heavy lifting I wonder if there are any other (for example binary) representations that would take the contents of a properly parsed object into a dataclass for storage or distribution.

Hence: I want to use the generated classes, but don't want to go back into XML to store the modified results, and then parse it again when required. XML -> dataclass -> intermedate presentation -> dataclass -> (eventually) XML.

Anything already available that quickly can do this job?
