## Description

Metadata is a PHP library for loading and managing class, method, and property metadata from inline annotations, YAML, XML, and PHP configuration files. It acts as an object-relational mapping support tool, helping persistence layers and serializers inspect PHP object structures through unified metadata drivers.

The library parses configuration data using specialized drivers to populate internal metadata structures, abstracting disparate data sources into a single consistent interface for inspecting classes and properties. It supports chain-based driver fallback, allowing multiple metadata loading strategies to combine sequentially so the system falls back through different sources until data is found. Additionally, developers can extend the base metadata class hierarchy to store application-specific properties and flags for classes, methods, and properties.
