roc-validator 0.2.0

A Python package to validate RO-Crates

rocrate-validator

A Python package to validate RO-Crate packages.

• 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.

Setup

Follow these steps to set up the project:

1. Clone the repository

git clone https://github.com/crs4/rocrate-validator.git
cd rocrate-validator

2. Set up a Python virtual environment (optional)

Set up a Python virtual environment using venv:

python3 -m venv .venv
source .venv/bin/activate

Or using virtualenv:

virtualenv .venv
source .venv/bin/activate

This step, while optional, is recommended for isolating your project dependencies. If skipped, Poetry will automatically create a virtual environment for you.

3. Install the project using Poetry

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

poetry install

Usage

After installation, you can use the main command rocrate-validator to validate ROCrates.

Using Poetry

Run the validator using the following command:

poetry run rocrate-validator validate <path_to_rocrate>

Replace <path_to_rocrate> with the path to the RO-Crate you want to validate.

Type poetry run rocrate-validator --help for more information.

Using the installed package on your virtual environment

Activate the virtual environment:

source .venv/bin/activate

Then, run the validator using the following command:

rocrate-validator validate <path_to_rocrate>

Replace <path_to_rocrate> with 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
