Scenario: Creating a new answer (POST)

Posting to the answers collection endpoint and including a link to an existing Person resource will allow you to create a new answer associated with that question and person. The response is the new answer 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 answer (PUT)

You can update an answer by calling a PUT operation on that answer's endpoint. Your PUT should contain fields that you want to update. Missing fields will be ignored by the receiving system.
