Hi Robert,

first: thanks for your answers.

One key concept seems missing here (at least to my attention):
Aggregates

They are on of the key elements of the object model in DDD, liky you 
surely know.
But aside one mention in the docs (page Persistance) I could not find 
any other reference. The good doc page about Objects doesn't even state 
them. It's only mentionted in the context of the persistance but not the 
creation and access of domain objects.
Or are the examples, i.e. the blog example,  build on the assumption 
that they are aggregate (roots)?

Another question is: there is only one repository for all objects, 
right? A kind of repository factory, I guess.
But what if I like to have my own repositories (just like I do for 
almost all aggregate roots because they have all different interfaces) 
except for simple entities, like lookups?

Perhaps I've overssen some concepts or the docs quite uncomplete.

Thanks for clarification,
Nino
