## What it is
schema-dts provides TypeScript type definitions for the Schema.org vocabulary in JSON-LD format, exposed as discriminated type unions for autocomplete and stricter validation. It includes a companion CLI (schema-dts-gen) for generating typings from specific Schema.org versions.

## Use cases
- add schema.org structured data to a website with type safety
- generate typescript types for json-ld schema.org vocabulary
- validate json-ld structured data in typescript
- emit seo rich-result metadata like Product or Person from a node app
- type-check @graph json-ld documents

## When to choose
- you write JSON-LD structured data in TypeScript and want completions and compile-time validation
- you need typings pinned to a specific Schema.org version or layer
- you want discriminated unions across Schema.org types

## When to avoid
- you need runtime validation of JSON-LD documents rather than compile-time types
- your project is not TypeScript/JavaScript
- you need full JSON-LD processing like framing or expansion
