Notes:The loader updates existing collections and is different from a
reader that would create new (detached) object instances.
The loader also creates objects, but it adds them to an existing
(attached) collection.
- Part of the reason for using this also for create is that
we want to support parent-child import from JSON that has
foreign key hidden. dataset:read-json cannot infer the relationship
into a new dataset in this case, so we need to call the collections
which will load the json into an existing context.
