SHACLER Generator

SHACLER Generator is a tool for generating human-readable documentation from SHACL shapes. It parses SHACL .ttl files, extracts node shapes, property shapes, and their constraints, and produces Markdown documentation. This makes it easier to understand and maintain your SHACL definitions, similar to how Swagger visualizes JSON Schemas.

Features

• Parses NodeShapes and PropertyShapes from SHACL .ttl files.
• Extracts and displays SHACL constraints, including property paths and their cardinalities.
• Produces Markdown documentation for easy sharing and integration into CI/CD pipelines.

Installation

This project uses Poetry for dependency management. To set it up:

1. Ensure you have Python 3.7+ and Poetry installed.
2. Clone this repository:

   git clone https://github.com/YourUsername/SHACLER.git
   cd SHACLER

3. Install dependencies:

    poetry install

   This will create a virtual environment and install all required dependencies.

Usage

The main entry point is main.py. To generate documentation:

poetry run python main.py --input <INPUT_DIR_OR_FILE> [--output <OUTPUT_DIR>]

Arguments:

• --input: Required. Path to a SHACL file or directory containing SHACL .ttl files.
• --output: Optional. Directory where the generated Markdown files will be placed. Defaults to ./docs if not specified.

Example:

poetry run python main.py --input ./shacl_files/schema/src/shacl --output ./docs

After running this command, look inside the selected directory. You will find Markdown files with documentation for your shapes.

Testing

poetry run pytest

Further Development

• All formatting rules are hardcoded. Implement a configuration system to control documentation generation
• Add more test. Ensure all SHACL features are covered.
