There are several metadata fields available for Items in the Details section of Item Settings, which authors can use to provide more information about the Item or to collaborate with other authors while creating the Item. All text entered for the notes, source and description metadata fields is made searchable in the Author API, but will not be visible to the student at any stage.
The Notes field can be used to provide notes to other Authors on the Item’s content when Items are being created and reviewed between multiple Authors.
The source field can be used by Authors to provide information on the source of the Items content.
The description field can be used by Authors to provide a description for the Item.
The acknowledgements field can be used by Authors to provide copyright acknowledgement for the Item content. Acknowledgements entered here can be configured to dynamically appear on the Activity Outro Item. This is particularly useful for adaptive Activities as you won't know which Items will appear in the Activity.
The visibility of the acknowledgements field can be controlled by the acknowledgements initialization option in Author API.
The difficulty level can be used to provide a difficulty level to your Item for internal reference, or when using adaptive assessments.
