WEB UI framework/method.
HTML / forms are better for accessibility etc etc
per @cyrin , the WEB UI people should talk about their choices and come to a decision on how you want to approach the web UI, will it be heavily JS, or a mix of JS and traditional HTML/forms, or something else all together? Me being more of a backend developer brought this up, because it might affect our choices on the backend. Heavy JS would mean we would be more service oriented handing out JSON for you to consume. @meltheadorable mentioned accessibility(A11Y) as a potential reason to think about traditional HTML/forms instead of heavy JS UI's. Also what if any UI frameworks you want to use.
Anyways, this is for anyone interested in the UI development portion to get their say! :)
