• DataCanon input: create DataCanon Instances (DCIs) from conventional objects, Shorthand, or files.
• Schema projection: optional DataCanon Type (DCT) constraints, defaults, choices, and processed output.
• Schema composition: inheritance, field-property overrides, copying, and removal.
• Child schemas: validate nested data while keeping inheritance separate.
• Application construction: conventional conversion and constructor arguments.
• SchemaCommandLine: options, files, nested commands, completion, and attribute output.
• Attribute output: property discovery, external names, and output controls.
• Output and application reports: DataCanon (DC) output and application-owned presentation.
• Migrating from numeric coercion: replace the former DataSchemer (DS) input model.

The Reference collects the behavioral rules, Python interfaces, and error details.
