How does Freeconf implement User Data validation against Yang Model and its subsequent persistance in a DataStore

[nishantrai5]

Wordings and Terminologies maybe incorrect. Please Ignore!

Assuming we have a YANG Model say "interface.yang". Reading the docs I figured Freeconf can serve Restconf endpoints against the Yang Model. Now when a user sends a post request to create a new interface, does the user data validation validation happen automatically against the Yang Model or do we re-implement the same in Go with various listeners. Same goes for things like Patch,Put and delete.

Additionally how are we persisting the user data in a datastore? Do we implement a way to update/get the user data once validation is successfull into a DB or something?

If both my above assumtion are correct, then is the YANG model only here for generating a unified way to create go structs?
