That's the case for scalar values, but it isn't the case for references to
other objects.

So, you almost got it right. As per sec 2.9.2.1 of the RO spec, the value
must be a json-node with a "href", ie:
{ "toDoItem":
{"value":
{ "href": "http://localhost:8080/restful/objects/TODO/L_18"; }
}
}
~~~
Your next question, I suspect, will be: "how do I know which hrefs to
provide?" In the Wicket viewer, we have support for the autoComplete
facet, and so render a drop-down. In the RO spec v1.0, there is no support
currently for autoComplete, so there is no easy way to support it.
I am working on v1.1. of the spec that defines this capability. A couple
of ideas for you in the meantime:
- extend the dom application to support choices (this is defined in the RO
spec), and render a drop-down of these
- cache objects identifiers as they are visited and make them available in
a drop-down (as "recently viewed")
- provide some sort of ability to pin or bookmark objects (eg onto a
"shelf" area) so that they can then be dragged down into the slot
afterwards.
