Implementing a new COMMAND CLASS

I have a zwave RFID reader which uses command classes which are not yet supported by openhab.
I have access to an experienced java developer who might be able to do this for the community.
Is there something already prepared that points him in the right direction for a starting point?
Or can anyone direct him to the correct bit of code?
He will follow existing instructions for creating his own development environment.
Thanks all

I know that there are people on this forum who are keen to use an RFID tag reader. If someone can just tell us where to start (ie by telling us where an existing COMMAND CLASS is defined), we could be getting on with this.

I’m no expert, but I think it’s here

Thanks Rich, that looks promising.
Much appreciated
