Other ddd frameworks, libs, ...

Other ddd frameworks, libs, ... may already have similar annotations (or even interfaces).
Did you investigate, or do you know what is out there ?

To be honest, I don't know about any other frameworks which might offer similar annotations. Most frameworks I have seen expose base classes which need to be subclassed by your own project. I'd be happy to hear about other libraries/frameworks which offer similar tooling. Let me know, if you have some.

This seems interesting:
https://github.com/xmolecules/jmolecules

..but I like your considerations about overlapping annotation names (@Entity @Repository) better

and there is no "kmolecules" yet :)
