An element collection has the contents of a view or module. The URI for an element collection is available in the service document and the general URI is in the form:

The JSON representation of the element collection contains a URI for each element in the element collection. Depending on the link that was chosen in the service document, the collection might include attribute values and might be structured as tree or a flat list.

A single element contains all attribute values and contains more details than the collection.

If a collection is an Add view or a module, you can add an element to the collection by using a POST operation. The body of the request must contain a JSON representation of the element. If the collection is an Add view, the contents of the view are in the folders. The folders can be parents when a new element is added.
