One important project catalyzed by the 2025 Congressional Hackathon was the coming together of a Legislative branch data map, the existence of which had been requested by Appropriators. The map is an effort to identify across the Legislative branch the different sources for congressional data and drew rhetorical inspiration from the 2013 executive order on making open and machine readable the new default for government information, the 2018 Open Government Data Act, and advocacy from public-interest minded groups.

The map data was seeded from my 2023 biased yet reliable guide to sources of information and data about congress and collaborations from governmental members of the Congressional Data Task Force, although its GitHub repository quickly drew pull requests from hackathon participants as well. In other words, anyone can suggest items to add to the list of Legislative branch data sources and that list can point to official and non-official sources for data. The map improves the findability of information and makes it discoverable when someone has done the hard work to refine that information into a useful format.

Here is where you can find and suggest edits to the Legislative Branch Data Map, version 0.1.
