Hi Devs,
I'm not a contributor but I think option 3 would be a mistake - it will
contribute to poor separation of concerns through obfuscation. Option 1 is the
best choice of the three presented.
Regards,David.

OK, so it comes down to either:
option 1:
@DomainEntity(persistence=JDO|EXTERNAL)@ViewModel
with
@DomainEntityLayout@ViewModelLayout
where:* is symmetrical* some attributes of @DomainEntity don't apply if
persistence=EXTERNAL* the two layouts are basically identical to each other
--- or ---
option 2:
@DomainEntity(persistence=JDO|EXTERNAL)@ViewModel
with
@DomainObjectLayout
where:* not symmetrical* some attributes of @DomainEntity don't apply if
persistence=EXTERNAL
--- or ---
option 3:
@DomainObject(persistence=JDO|EXTERNAL|VIEW_MODEL)
with
@DomainObjectLayout
where:* is symmetrical* some attributes of @DomainEntity don't apply if
persistence=EXTERNAL or VIEW_MODEL* concept of view model is less visible
Cast your votes, please!

As currently there's no "special" support for AggregateRoots or
ValueObjects, no more annotations are needed.
Sounds like a vote to deprecate. Jeroen has said the same thing. Perhaps
they should be deleted in v2.0 and reappear, if we want them back, in v3.0.
I agree with Jeroen.
Currently there's nothing specific about Aggregate Roots on Apache Isis, at
least on the most used modules, AFAK.
* replace @DomainObject(viewModel=false) with
@DomainEntity(persistence=JDO)
... this would be the default
I like it :)
* replace @DomainObject(viewModel=true) with
@DomainEntity(persistence=EXTERNAL)
This one also!
... for view models representing externally-persisted entities. In the
Javadoc, say that auditing, publishing and bounded are not supported for
these
* keep @ViewModel
... extend to include the non-entity stuff from @DomainObject that does
apply (basically, I think that's just "objectType" )
... the intention being that this is used for application-layer views.
I agree. It should be kept for those use cases.
keep @DomainObjectLayout, because everything in it applies equally to both
view models (either variety) and JDO entities.
Mmmmm.... I would prefer to keep symmetry... I know it introduces some
redundant checks on implementation but, from the user's perspective, is a
clearer model ...
I'll reply on your points on @Property and @Parameter separately.
Thx
