Package-level declarations

Abstract base class for metadata parsers that provides caching functionality to improve performance by avoiding repeated parsing of the same class metadata. This class implements a thread-safe caching mechanism using ConcurrentHashMap to store parsed metadata.

Marker interface for metadata objects in the Wow framework. Classes implementing this interface represent parsed metadata information about various components such as commands, events, aggregates, and other framework elements. This interface serves as a type constraint for metadata objects that can be cached and managed by metadata parsers.
