Item resources are sometimes presented as collections of items. For example, calling the items endpoint on a particular list will return a collection of all the items in that list.

Scenario: Creating a new item (POST)

Posting to the items collection endpoint and including a link to an existing resource will allow you to create a new item associated with that list and other resource. The response is the new item that was created. While each implementing system will require different fields, any optional fields not included in a post operation should not be set at all by the receiving system, or should be set to default values.

Scenario: Modifying an item (PUT)

You can update an item by calling a PUT operation on that item's endpoint. Your PUT should contain fields that you want to update. Missing fields will be ignored by the receiving system. Systems may also ignore PUT values, depending on whether fields you are trying to modify are read-only or not. You may set an attribute to nil by including the attribute using nil for value.

Scenario: Optimized List Item Retrieval (GET)

Where supported by the API provider, a single request may retrieve one item (or a collection of items) along with the resource(s) they represent. For example, calling the items endpoint on a particular list will return a collection of the items in that list. If the server optionally embeds into each item the resource to which the item refers, then the client will not need to make further API calls to retrieve the end resource(s).

The following example retrieves a list collection where each item in the embedded list links to an osdi:person resource and also embeds the osdi:person resource within it:
