ember.js rest JSON recursively nested with same model

below is an example of the JSON I get from my REST endpoint. I need to create a tree-like structure from the subcategories arrays, which, as you can see, are recursively nested.

I searched and tried for almost a week now, but am unable to come up witha fully working solution -- the best I got so far was that the subcategories appeared both as children of their parent subcategory (as desired), but also as normal top-level nodes, which I clearly do not want.

my question is simply: how do I model this so that ember.js is able to create the desired tree-like structure?

I don't think this is very difficult for an experienced ember user, but as usual ember's documentation it is neither up-to-date nor does it cover more than trivial concepts.

wherever I look, the concept of such a nested structure seems to be alien (all nesting I find is with different types, but that is exactly what I don't need). the JSON format is immutable, I have to work with it the way it is.

I created my project with - ember-cli 0.2.7 - ember.js 1.13.0 - ember-data 1.13.4 using DS.RESTAdapter and DS.RESTSerializer

{
"id": 28,
"hassubcategories": true,
"CategoryName": "By Asset Type",
"subcategories": [
    {
        "id": 29,
        "CategoryName": "Images",
        "hassubcategories": true,
        "subcategories": [
            {
                "id": 30,
                "CategoryName": "Illustrations",
                "hassubcategories": false
            },
            {
                "id": 31,
                "CategoryName": "Pictures",
                "hassubcategories": true,
                "subcategories": [
                    {
                        "id": 61,
                        "CategoryName": "BMP",
                        "hassubcategories": false
                    },
                    {
                        "id": 32,
                        "CategoryName": "EPS",
                        "hassubcategories": false
                    }
                ]
            }
        ]
    },
    {
        "id": 73,
        "CategoryName": "InDesign  (related)",
        "hassubcategories": false
    }
]

}

and this should render in a template to a tree-like list Images - Illustrations -- BMP -- EPS Indesign (related)

thanks for any help.
