Implicit mapping I call Managed Object Graphs MOGs. So you
can write<br>
Person( address.street == "my road" )<br>
<br>
And that internally would get translated too<br>
$p : Person()<br>
Address( person == $p, street == "my road" )<br>
<br>
As there is no doubt that the current explicit bindings
approach on objects is too verbose and hard to read. Nested
accessors add a lot of readability.<br>

So what if Address is not an inserted fact? So far, a CE with
type Foo(...) implied the existence of a fact of that type.
I'm not sure that inserting some object should imply the
insertion of all of its descendants as facts as well...<br>

You don't necessarily have to insert Address. It can attach a
listener, assuming the pojo supported it, when it's accessed in a
pattern - allowing the pattern to receive updates from nested
objects.<br>
<br>
Whether something is inserted or not can be annotation driven.
Something can't be inserted anyway unless it has the necessary
references for the joins.<br>
<br>
I want to look at a full range of MOGs to automate and semi-autimate
things with regards to nested structures. At the moment there is no
best practice and DRL (or any other rule language) does not make
this nice. We ALL suck for compact nested accessors.<br>
