I have never used FOLDERs in anger. Just cannot figure out how to associate a composition/contribution with a FOLDER, either in Better Ehrscape or the openEHR REST API.

Any pointers?

Well a Contribution causes modifications to the Folders structure, just like any other structure. Contribution = version change set record.

Hi Ian, 

this example is from the integration tests of EHRbase. Should hopefully work:

    {
      "_type": "FOLDER",
      "name": {
        "_type": "DV_TEXT",
        "value": "root"
      },
      "archetype_node_id": "openEHR-EHR-FOLDER.generic.v1",
      "folders": [
        {
          "_type": "FOLDER",
          "name": {
            "_type": "DV_TEXT",
            "value": "subfolder 1"
          },
          "archetype_node_id": "openEHR-EHR-FOLDER.generic.v1"
        },
        {
          "_type": "FOLDER",
          "name": {
            "_type": "DV_TEXT",
            "value": "subfolder 2"
          },
          "archetype_node_id": "openEHR-EHR-FOLDER.generic.v1"
        }
      ],
    	"items": [
          {
      		"id": {
      			"_type": "HIER_OBJECT_ID",
      			"value": "d936409e-901f-4994-8d33-ed104d46015b"
      		},
      		"namespace": "my.system.id",
      		"type": "VERSIONED_COMPOSITION"
      	}
      ]
    }

In my understanding, the composition is linked to the root folder. If you need to associate compositions with a sub folder, you can create an item array under that also.

Thanks, @Dileep_V_S.  It works as you suggested, and even with "items": [] or without it.
