FBI Investigation Context: Charlie Eppes discovers list directories on Rachel Lawton's hard drive. By inspecting spacing patterns, bounds, and digits, we deduce the context of unlabeled data (metadata).

Step 1: What is Metadata?

Numbers represent entities in the physical world. In intelligence audits, raw database logs are frequently stripped of headers. We define metadata as the structural attributes, formatting rules, limits, and patterns that describe the data.

For instance:

  • A pattern of XXX−XX−XXXXXXX-XX-XXXX implies a U.S. Social Security Number.
  • Ratios ending in standard denominators like /200/200 or /20/20 represent Snellen visual acuity eye tests.
  • Frequencies bounded inside [88.1,107.9][88.1, 107.9] with odd decimals signify FM radio broadcasts.

We use logical constraints to identify what these columns represent.
