UI Annotations are a way of linking up screen shots of system UI with fields in messages. UI annotations can be useful for non-technical stakeholders to help them understand how messages being mapped by relating them to the systems they are familiar with.
Adding UI Annotations to Messages
Select an element in a message and click the 'Add UI Annotation' button.
Choose an existing screen-shot file if one has previously been uploaded, or click 'Choose File' and upload a new one. Then click the button marked 'Save Image'.
Move the circular guides so the rectangle marks out the field on the screen-shot that corresponds to the field selected in the message, and then click 'Save'.
Once the UI annotation has been saved it can be edited by clicking on the thumb-nail, or additional UI annotations can be added to the message element.
