This looks very cool. I'd love to know if it'll be fully open source -- the NEH grant seems to imply that it will at least be partially opened up (https://apps.neh.gov/publicquery/main.aspx?f=1&gn=HAA-287859-22), but then they say "patent pending" on the website, which is typically incompatible with a wider open source release. I also didn't find a GitHub repo or anything like that.
