Requirements

• Python 3.7+
• No external dependencies (uses Python dataclasses and standard library)

---

Installation

From PyPI

pip install remake_dpp

From Source

git clone git@github.com:nmis-group/remake_dpp.git
cd remake_dpp  
pip install .

---

Usage Example

We have created a simple python file to showcase the usage.

cd remake_dpp

# 1. Generate a sample DPP JSON file (using helper script or usage_test logic)
python generate_dpp_json.py

# 2. Run the main usage script with input file and target schema
python usage.py coffee_machine.json ECLASS
# python usage.py coffee_machine.json ISA-95

---

Quick Start Steps

1. Install with pip or from source.
2. Import model layers and part classes.
3. Create instances and assemble your passport.
