Re: DDD and cross domain AR references for UI

I'd look into composite frontends and autonomous business components.


It sounds like the rendering of your profile part belongs to the social 
bc that owns the data.


If you still want to integrate the bcs through REST endpoints you could 
e.g. create a model for describing how data should be rendered, but this 
can get complex very quickly.


It's also possible that you're missing a context or an aspect in your 
model.
