Am I being dumb or does this not actually contain the facts about the tax code? Is the /demo/all-facts file supposed to be the “real” facts? Are the XML fact files provided in another location?

It’s pretty cool to see the way that the IRS handles defining and maintaining its tax calculations, but also a machine-readable tax code seems cool too.

I believe the actual IRS tax code implementation is in a separate repo here: https://github.com/IRS-Public/direct-file while the originally linked repo is the fact graph tooling decoupled from the tax implementation.

Look like many of them are specifically the xml files here:

As far as I am aware, fact just means shared assumption. This seems entirely reasonable for a tax code.

It looks like just an HTTP interface to a database, not the actual data.
