### Core Components

1. **DocumentIR (Intermediate Representation)**: Unified abstraction for all documents, containing document tree, metadata, assets, etc.
2. **BaseParser (Parser Base Class)**: Defines the parser interface, parses various formats into DocumentIR
3. **BaseRenderer (Renderer Base Class)**: Defines the renderer interface, renders DocumentIR into various formats
4. **ConverterRegistry (Registry)**: Manages all parsers and renderers, provides format lookup and auto-matching
5. **DocumentConverter (Conversion Engine)**: Coordinates parsers and renderers to complete document conversion
