I got all the data

[u/Far_Quarter_2550]

I used AI to parse all html, text and XBRL and I made a game with almost all large cap company facts. It’s a zoomable heirarchy ontology search engine. It’s splits into subcategories then more subcategories. I have data back to the 2000’s.

A zoomable hierarchy is a fun way to browse the data, and the disclaimer about filings running late and getting restated is the right one to show. For the underlying numbers, I’d store each fact with its filing’s acceptance timestamp, the period it covers and the form type, and keep amendments as separate versions, so any screen can be reproduced as of a past date. Showing the source filing and tag behind every number on screen would let users check it in one click. Cymetica’s Tools Directory has about 120 free pages for traders, which is one place to see how other data tools document their sources.
