Great work! Inspiring for me, as I am trying to build a better UI to consult the document “Base Nacional Comum Curricular” and help all schools to use it for their curriculum creation.
Sadly, no. I moved back to the US and then worked on other things, but still maintained it for a few years until the ENEM microdata started to get released super behind schedule, then I gave up on the whole thing. Was called dadosdoenem.org, and you probably may encounter a reference to it here or there somewhere online. Good times... insane to think it was over a decade ago.
Is your site still up?
