How It Works
A technical-level overview for people evaluating this rather than just clicking through it. This is a summary, not the full internals - some detail is intentionally left out.
The pipeline
- Canonical schema. The full national MMUCC standard - every element, every enumerated code value - is modeled directly from the government's own official machine-readable schema file, not retyped by hand from the prose guideline. That matters: a hand-transcribed standard drifts from the real one over time and in small, easy-to-miss ways. This one doesn't, because it's generated straight from the source.
- Per-state mapping. Each state gets its own configuration describing how its real, existing crash-data fields correspond to the national standard's elements - built by someone who actually read that state's own code manual, not inferred automatically. A state's code "5" doesn't necessarily mean the same thing as the standard's code "5," and that translation is the real work.
- Validation. Every mapped crash record is checked against the government's own published cross-field consistency rules - real logic like "if the first harmful event was another vehicle, at least two vehicles need to be marked as being in-transport." This isn't a plausibility check invented for the demo; it's the federal government's own rule set, implemented directly.
- Export. A validated record can be produced in the standard's own compliant output format - the shape a state would actually need to hand off.
What's real about this demo
- The schema, the validation rules, and the export format are all sourced from the government's own official technical package - not approximated.
- The five states shown (Nebraska, Iowa, Illinois, DC, Kansas) each map real public crash data pulled from that state's own live source, not synthetic test fixtures.
- The mapping and validation logic you're seeing run is the same logic the underlying engine actually executes - the site isn't showing a separate description of it.
The specifics of how a state's mapping is actually built and matched aren't detailed here - if you'd like a deeper technical walkthrough, get in touch directly.
