-The Abstract Document design pattern is a structural design pattern that aims to provide a consistent way to handle hierarchical and tree-like data structures by defining a common interface for various document types. It separates the core document structure from specific data formats, enabling dynamic updates and simplified maintenance.

 Real-world example
 
-> Imagine a library system where books can have different formats and attributes: physical books, eBooks, and audiobooks. Each format has unique properties, such as page count for physical books, file size for eBooks, and duration for audiobooks. The Abstract Document design pattern allows the library system to manage these diverse formats flexibly. By using this pattern, the system can store and retrieve properties dynamically, without needing a rigid structure for each book type, making it easier to add new formats or attributes in the future without significant changes to the codebase.

 > An object-oriented structural design pattern for organizing objects in loosely typed key-value stores and exposing the data using typed views. The purpose of the pattern is to achieve a high degree of flexibility between components in a strongly typed language where new properties can be added to the object-tree on the fly, without losing the support of type-safety. The pattern makes use of traits to separate different properties of a class into different interfaces.

 The key idea behind the Abstract Document design pattern is to provide a flexible and extensible way to manage different types of documents or entities with shared and distinct attributes. By defining a common interface and implementing it across various document types, you can achieve a more organized and consistent approach to handling complex data structures.
