Data Classification & Retention

Classification schemes that had to survive a court rather than an audit.

Also known as Retention Schedules, Legal Hold, Defensible Disposition, Chain of Custody

Left to right is time. Each row is one of the 14 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Set enterprise standards for data classification, retention and disposition across agencies with incompatible obligations.

Florida public records law made retention schedules, disclosure exemptions, legal hold and defensible disposition statutory obligations rather than internal policy, which meant the classification scheme had to survive a court rather than an audit.

Chain of custody was designed into the architecture rather than into procedure — most explicitly in the Medical Examiner’s Office integration, where a forensic case moving between nine federated subsystems had to remain provably intact.
