What you propose would certainly be possible. You'd have to write a
custom EntityProvider that will serialize and deserialize instances
of classes with those annotations.
Have you looked at the JSON support in the JAXB entity provider that
Jakub added ? Take a look at the Bookmark example that shows it in
use. You might not be able to get the exact JSON format you show
below but I'd bet you could get close just using some of the JAXB
annotations.
