Canonical form
A canonical form is a standardized representation chosen to express equivalent values or entities consistently.

A canonical representation is a normalized form that consistently identifies an entity or concept independently of its alternative textual expressions.
- How it is used
- Maps matched query wording to known entities or semantic functions for query interpretation.
- How deep it goes
- Defines entity fields and walks through extraction and typed-query construction; resolves illustrated ambiguity by popularity rather than contextual disambiguation.
- Examples
- Uses “cto” expansions and a “top kimchi near charlotte” query tree to show normalization and interpretation.
- What you can do after
- Apply it via a Solr text tagger and Python entity extractor to map query variants into typed entities.
API Design Patterns
A canonical form is the single standardized representation selected as the definitive form of equivalent values or inputs.
- How it is used
- Uses standardized representations to fingerprint HTTP requests and make identifiers readable and mistake-tolerant.
- How deep it goes
- Explains ordering, casing, hashing, and tolerant decoding through concrete implementations, stopping short of signature computation.
- Examples
- Uses a signed PATCH request and a hyphenated Crockford’s Base32 identifier.
- What you can do after
- Build it from scratch by assembling deterministic request fingerprints and defining tolerant identifier decoding.
