I&#x27;ve been working on a project like this for some time now - and wresting with whether I want to go the community-based vs. closed source model.<p>The problems listed below are pretty exact: huge data sets, lots of cleaning and normalizing, and the snail mail&#x2F;cd problem is real. Additionally, I&#x27;d note that ~40% of the states [somehow] charge for the data...it takes six digits to get a snapshot of all 50 states - and certain states (looking at you FL) say that they do not store the historical, meaning you have to connect with the local BoE&#x27;s to aggregate the data.<p>A part of me [now] wants to open source this because of the DNC&#x27;s actions.
