Web-data guides
Methods we use and automate, written to be useful even if you never touch Zillusion. No tricks, no tool lock-in — just how careful teams get web data they can rely on.
All guides
- How to turn any website into a dataset — the six-step lifecycle: define the record, find the best access path (API > file > embedded > HTML), extract, verify, version, monitor.
- How to verify scraped data is actually correct — the 4-check method (clean re-run, reproducibility, resample against the live source, field semantics re-proven) and the independence rule behind it.
