rocrate-validator

A Python package to validate RO-Crates.

• Supports CLI-based validation as well as programmatic validation (so it can easily be used by Python code).
• Implements an extensible validation framework to which new RO-Crate profiles can be added. Validation is based on SHACL shapes and Python code.
• Currently, validations for the following profiles are implemented: RO-Crate (base profile), Workflow RO-Crate, Process Run Crate. More are being implemented.

Note: this software is still work in progress. Feel free to try it out, report positive and negative feedback. Do send a note (e.g., by opening an Issue) before starting to develop patches you would like to contribute. The implementation of validation code for additional RO-Crate profiles would be particularly welcome.

Installation

You can install the package using pip or poetry. The following instructions assume you have Python 3.8 or later installed.

Optional Step: Create a Virtual Environment

It’s recommended to create a virtual environment before installing the package to avoid dependency conflicts. You can create one using the following command:

python3 -m venv .venv

Then, activate the virtual environment:

• On Unix or macOS:

source .venv/bin/activate

• On Windows (Command Prompt):

.venv\Scripts\activate

• On Windows (PowerShell):

.venv\Scripts\Activate.ps1

1. Using pip (from PyPI)

You can install the package using pip:

pip install roc-validator

2. Using poetry (from source)

Clone the repository:

git clone https://github.com/kikkomep/rocrate-validator.git

Navigate to the project directory:

cd rocrate-validator

Ensure you have Poetry installed. If not, follow the instructions here. Then, install the package using poetry:

poetry install

Usage

After installation, use the rocrate-validator command to validate RO-Crates. You can run this in a virtual activated environment (if created in the optional step above) or without a virtual environment if none was created.

1. Using the installed package

Run the validator using the following command:

rocrate-validator validate <path_to_rocrate>

where <path_to_rocrate> is the path to the RO-Crate you want to validate.

Type rocrate-validator --help for more information.

2. Using poetry

Run the validator using the following command:

poetry run rocrate-validator validate <path_to_rocrate>

where <path_to_rocrate> is the path to the RO-Crate you want to validate.

Type rocrate-validator --help for more information.

Running the tests

To run the tests, use the following command:

poetry run pytest
