QuestionFormAnswers

The QuestionFormAnswers data format describes answers submitted by a Worker for a HIT, or for a Qualification test.

A QuestionFormAnswers data structure is a string value that consists of XML data. The XML data must conform to the QuestionForm schema. See WSDL and Schema Locations for the location of this schema. For more information about using XML data as parameter or return value, see Using XML Parameter Values.

The QuestionFormAnswers data structure is used as a response element for the following operations:

The QuestionFormAnswers data structure is a value in an Assignment data structure, and a value in a QualificationRequest data structure.

All elements in a QuestionFormAnswers belong to a namespace whose name is identical to the URL of the QuestionFormAnswers schema document for the version of the API you are using.

A QuestionFormAnswers element contains an Answer element for each question in the HIT or Qualification test for which the Worker provided an answer. Each Answer contains a QuestionIdentifier element whose value corresponds to the QuestionIdentifier of a Question in the QuestionForm. See the QuestionForm data structure for more information about questions and answer specifications.

If the question expects a free-text answer, the Answer element contains a FreeText element. This element contains the Worker's answer.

If the question expects a multiple-choice answer, the Answer element contains a SelectionIdentifier element for each option the Worker selected. If the Worker did not make any selections, the Answer will contain zero SelectionIdentifier elements. The identifier corresponds to the SelectionIdentifier for the selection provided in the answer specification for the question.

If the multiple-choice question includes an OtherSelection field, and the Worker enters data into this field, that data appears in the Answer in an OtherSelectionText element. If the Worker both selects an option from the list and provides text in this field, both values will be present in the answer.

If the question expects an uploaded file as an answer, the Answer element contains an UploadedFileSizeInBytes element, and an UploadedFileKey element. UploadedFileSizeInBytes indicates the size of the file the Worker uploaded. UploadedFileKey is a unique identifier for the file, unique with respect to other files that Workers may have uploaded. To retrieve an uploaded file, your application calls the GetFileUploadURL operation, which returns a temporary URL your application can use to download the file. See the GetFileUploadURL operation for more information on retrieving uploaded files.

Answer data will always conform to the answer specification provided in the HIT question, or in the Qualification test question.

The following is an example of a complete QuestionFormAnswers data structure. Remember that this value will be returned as a single return value, XML escaped in the response.
