django_pid: Extensible PID Pool Management for Django

django_pid is a Django app for managing persistent identifiers (PIDs) such as Handle, DOI, ARK, and more. It provides:

• PID pool management: Pre-registers and reserves PIDs, ensuring a ready supply for assignment to resources.
• Server abstraction: Supports multiple PID server types via a flexible factory pattern.
• Asynchronous operations: Uses Celery tasks for pool replenishment, health checks, and retry logic.

Key Features

• Extensible PIDService Factories: Easily add support for new PID systems by registering custom service builders (see object_factory.py). The default implementation uses the PID4Cat Handle server, but you can plug in other PID services by implementing and registering a compatible factory.
• Robust pool lifecycle: Handles server outages gracefully, with local handle generation and exponential back-off retries.
• Django ORM integration: Models for PID servers, types, and pool entries, with custom managers for pool logic.

Installation

This project uses uv as the default Python package manager and runtime. Do not use pip directly.

uv sync  # Install all dependencies from pyproject.toml

For development tools and formatting:

uv run ruff check --fix .
uv run ruff format .

Usage

Add django_pid to your Django INSTALLED_APPS and migrate:

python manage.py makemigrations django_pid
python manage.py migrate

Configure PID servers and types via the Django admin or fixtures. The app will maintain PID pools and handle assignment automatically.

Extending with Custom PID Services

To support additional PID systems, implement a service class with the required interface (see pid_service_builders/pid4cat.py) and register it in the object factory (object_factory.py). This allows seamless integration of new PID backends without modifying core logic.

Project Structure

• src/django_pid/models.py: ORM models for servers, types, and PIDs
• src/django_pid/tasks.py: Celery tasks for pool management
• src/django_pid/object_factory.py: Generic factory for service builders
• src/django_pid/pid_service_builders/: Service implementations (default: PID4Cat)
