Result Data Extension

This extension is used to pass data in addition to a grade when using the outcome service

Introduction

If this extension is supported the consumer sends a list of accepted data values and the provider adds a resultData node to the result XML sent to the consumer.

Launch Parameters

Name Required Description
ext_outcome_data_values_accepted yes Presence of this key indicates that the consumer is capable of using the resultData extension. The value should be a comma separated list of: url, text, or values agreed upon between consumer and provider.

Tool Provider Response

If the provider wants to supply these values, it can augment the POX sent with the grading value. LTI replaceResult POX

Only one type of resultData should be sent, if multiple types are sent the tool consumer behavior is undefined and is implementation-specific.
