Business, property and inspection documents

Certificates, appraisals, inspection reports and the operational paperwork that runs a company.

The documents in this cluster look easy and are not. A certificate of origin is one page with fifteen boxes; a rate confirmation is one page with a number on it; an inspection report is a list of findings. What makes each of them hard is never the layout. It is that the fields carry meaning defined somewhere outside the page — a check digit that either computes or does not, a standard designation whose year suffix changes what was certified, a numbered list whose Part I and Part II mean opposite things, a severity word whose definition is printed on page three of the same report.

So these pages are about the specific thing each document type will do to you, and about the arithmetic or the cross-reference that catches it. The general machinery — schema design, confidence, review queues, the reading-order problems of a scanned page — lives in its own cluster and is linked rather than repeated here.
