SD - Tag Request

Sequence Diagram for a Tag Request

• Still need to verify this; I understand that 'tag' requests are still handled this way and that Display Groups are handled using an ID.
• After verification, I want to list out the packages involved so refactoring will be easier to understand. The reasons behind multiple back and forth between AJAX and other components isn't clear, but I think it has to do with being able to update the progress bar. Perhaps that could/should be factored out.
