UIO Architecture

I have created a UIO Options iteration page that is for now very barebones:


It contains a list of JIRA tickets that describe the actual work that we are planning to tackle first. Let me know if you see anything missing or in case I am describing something incorrectly (I tried to write those JIRA's up based on the notes that were sent previously in this thread :) ).
