Suppose I have documents

thing { name:blah, owner: persons/1, id:things/1 }
thing { name:other, owner: company/1, id:things/2 }

person { name: bob, id:persons/1 }|
company { name:fedex, id:company/1 }|

Is it possible to do something like

session.Load<Thing

No need

session.Load<Thing>(id).Include(x => x.Owner)

Will do

The server will look at the requested fields and pull the json docs from
store - it doesn't care about the type

No I don't want to do a multiple level include, I'm exploring allowing 1
type of document (Thing) to have multiple types of owners and from what
Itamar said it should. Actually typing out code this should be the real
usage correct?

Session.Include<Thing>(x => x.Owner).Load<Thing>("things/1");

This almost seems wrong as I really want to get back a company or a person
depending on Owner, but I see it's setup like this so i can properly use
strongly typed access to reach x=>x.Owner of Thing, correct? That using
less strong typing that it would be the same as:
Session.Include("Owner").Load<Thing>("things/1"); correct?

Too many questions :)

The syntax is actually

Session.Include<Thing>(x => x.Owner).Load("things/1");

And what it does is pull the JSON documents "things/1" and all other
documents that are mentioned in it's x.Owner property. It doesn't care
about the type. The client API will do the conversion for you when you
deserialize (e.g. call Load and use that ID)
