## What it is
A PHP library for managing class, method, and property metadata from multiple sources such as annotations, YAML, XML, and PHP configuration files. It abstracts the metadata source behind a common interface via a MetadataFactory and driver chain.

## Use cases
- read class and method metadata from annotations in php
- load configuration metadata from yaml or xml files
- build a common metadata interface across multiple sources
- attach custom metadata to php classes and properties
- implement annotation-driven behavior in a framework

## When to choose
- you need to read annotations or config-file metadata in a PHP project
- you are building a library that supports multiple metadata sources
- you want a stable, widely used metadata abstraction layer

## When to avoid
- you use PHP 8 native attributes and need no legacy source support
- your framework already provides its own metadata or attribute reader

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: developer-tools, web-development
- platform: php
- tags: metadata, annotations, php-library, reflection
