+## Overview
+
+**aas-standard-parser** is a Python library for parsing and handling Asset Administration Shell (AAS) standard submodels. It provides a comprehensive set of parsers and utility helpers to extract, interpret, and work with AAS structures.
+
+### Available Parsers
+
+* **AAS Parser**: Extract submodel IDs and references from Asset Administration Shell structures
+* **Submodel Parser**: Navigate and retrieve submodel elements using intuitive dot-separated paths with support for nested collections and indexed access
+* **AID Parser**: Parse Asset Interface Description (AID) submodels to extract interface metadata, properties, protocol bindings, and authentication details
+* **AIMC Parser**: Extract and process Asset Interface Mapping Configuration (AIMC) submodels, including mapping configurations and source-sink relations
+
+### Available Helpers
+
+* **Collection Helpers**: Work with submodel element collections, filter by semantic ID, and extract keys from collections
+* **Reference Helpers**: Handle AAS references, semantic IDs, and validate reference structures
+* **JSON Helpers**: Load and validate submodels from JSON files with structured error handling
+* **Utility Functions**: General-purpose utilities for logging, validation, and data transformation
+
+The library leverages the [python aas sdk framework](https://github.com/aas-core-works/aas-core3.0-python) to ensure compatibility with official AAS data models and structures.
