## What it is
Nette Schema is a PHP library for validating and normalizing data structures against a defined schema using a fluent Expect API. It processes arrays or objects (e.g., API payloads or config files) and returns normalized data or detailed validation errors.

## Use cases
- validate user-submitted API payloads in PHP
- validate and normalize configuration files
- enforce structure of nested arrays and objects
- validate JSON data against a schema
- normalize input data types before processing
- collect all validation error messages at once

## When to choose
- you need schema-based validation and normalization of arrays/objects in PHP 8.1+
- you want a readable, fluent schema definition API
- you need detailed, structured validation error messages
- you're already in the Nette ecosystem

## When to avoid
- you need JSON Schema standard compliance or interoperability
- your project is not PHP
- you only need simple type checks that built-in PHP functions cover

## Facets
- artifact type: library
- maturity: stable
- function: form-handling, serialization, configuration-management
- domain: developer-tools, web-development, apis
- platform: php, cli
- tags: data-structures, schema-validation, normalization, nette-framework, config-validation
