I remember about a decade ago, I wanted to analyze US Congressional votes to look for evidence of a possible third-party voting base in across-the-aisle votes.
The votes were generally published as XML documents, which was sort of annoying but a fun way to learn Python.
Nice to see things getting more standardized - I've been pleasantly surprised by how the US government's digital services have advanced in the past 10-20 years.
(Except for the contracted-out disasters like recreation.gov and V1 of healthcare.gov, of course.)
