## About

Recidemia is the world's largest classified recipe encyclopedia. Every recipe is
cataloged using the Recidemia Culinary Index (RCI), an ATU-style canonical
numbering system that gives each recipe type and regional variant a unique,
stable, citable identifier.

## Data Structure

The RCI taxonomy has four levels:

- Domain (XX): Broad culinary category (e.g., ND = Noodles & Pasta)
- Family (XX.NNN): Group of related types (e.g., ND.001 = Tomato-based Pasta)
- Type (XX.NNN.NNNN): Canonical recipe type (e.g., ND.003.0042 = Spaghetti alla Carbonara)
- Variant (XX.NNN.NNNN.NNN): Specific regional/cultural expression (e.g., ND.003.0042.001 = Carbonara Romana)

## URL Patterns

- Homepage: /
- Recipe page: /recipe/{variant-rci} (e.g., /recipe/ND.003.0042.001)
- Type page: /type/{type-rci} (e.g., /type/ND.003.0042)
- Family page: /family/{family-code} (e.g., /family/ND.001)
- Search: /search?q={query}

## Structured Data

Every recipe page includes Schema.org/Recipe JSON-LD with:
- Full ingredient list with amounts and units
- Step-by-step instructions (HowToStep)
- Prep time, cook time, total time (ISO 8601 durations)
- Serving count, difficulty level
- Dietary restrictions (vegetarian, vegan, gluten-free, etc.)
- RCI identifier for stable cross-referencing

Type pages include Schema.org/WebPage with ItemList of variants.
