Practical guidance for authoring Internet Object documents and schemas.
Type your fields in production. Prefer name: string, age: int over bare name, age; types catch bad data and document intent.
Use keyed schemas beyond trivial records. Positional (CSV-like) data is great for flat, fully-required records; reach for keyed fields once shapes get richer.
Put optional fields last in positional schemas. A leading optional field can swallow the next value (the first value provided fills the optional slot).
Reuse with references. Define a shape once as $address and reference it; change it in one place. See Composition & Reuse.
Quote ambiguous values. Quote strings that look like numbers, booleans, or null ("123", "true", "N"), contain commas, or contain : / / (URLs, times).
Pick the right number type. Use int/uint/intN for whole numbers, decimal (m) for money, bigint (n) for very large integers — not number for everything.
Mark nullability explicitly with the * suffix; mark optionality with ?.
Keep the schema in the header, data below ---. Use metadata keys for paging/status.
Use collections for many similar records; one schema validates them all.
Comment the why. Use # to explain intent, not to restate the obvious.
Stay in Internet Object when exactness matters. decimal, bigint, datetime, and binary can be lossy when converted to JSON — see JSON Compatibility.
