OAIS platform

Web API, built on Django, managing workflows for the CERN Digital Memory OAIS platform.

Main goals of the platforms are:

• Allow users to trigger the harvesting of resources and produce SIPs (using the bagit-create tool);
• Allow services and users to deposit SIPs and ingest them in the platform;
• Trigger preservation workflows;
  • Interface with a distributed deployment of Archivematica;
  • Send SIPs to Archiver.eu platforms and evaluate their interfaces, performance and behaviour on ingestions and processing metadata;
• Send prepared AIPs to the new CERN Tape Archive (CTA);
• Maintain a registry of the successfully harvested and ingested resources, processing and exposing metadata;
• Expose resources on an access system powered by InvenioRDM.

Run

A docker-compose setup is provided in this repository, bringing up the following services:

To quickly setup a development instance, featuring hot-reloading on the backend:

# Start by cloning oais-platform
git clone ssh://git@gitlab.cern.ch:7999/digitalmemory/oais-platform.git
# Inside it, clone oais-web
git clone ssh://git@gitlab.cern.ch:7999/digitalmemory/oais-web.git oais-platform/oais-web
# Build the web application
cd oais-platform/oais-web
npm install --force
npm run build
# Go back to the oais-platform folder and launch the docker compose setup
cd ..
docker-compose up

Node version 14.19.3 or newer is required for this (use node -v to check the current version).

If you also want the React application to hot-reload on file modifications, instead of running npm run build, keep a shell open and run npm run serve.

The following endpoints are then available, on localhost:

• / - Oais-web React application
• /api - Base OAIS Platform API endpoint
• /api/schema - OpenAPI 3 specification of the API
• /api/schema/swagger-ui/ - Swagger UI documentation for the API

See troubleshooting for more instructions on how to see logs and run commands in the single containers.

Django

To run these commands inside a Docker container, run it in the container shell with docker exec -it oais_django sh.

# python manage.py showmigrations
# Prepare migrations
python manage.py makemigrations oais
# Apply migrations
python manage.py migrate
# Create administrator user
DJANGO_SUPERUSER_PASSWORD=root DJANGO_SUPERUSER_USERNAME=root DJANGO_SUPERUSER_EMAIL=root@root.com python3 manage.py createsuperuser --noinput
# Run the application
python manage.py runserver

Run tests

python manage.py test

With docker-compose:

docker-compose down
docker volume prune -y
docker-compose -f test-compose.yml up --exit-code-from django

Code is formatted using black and linted with flake8. A VSCode settings file is provided for convenience.

Configuration

CERN SSO

To enable the CERN SSO login, set Client ID and Client Secret from your application on https://application-portal.web.cern.ch/. Documentation can be found at https://auth.docs.cern.ch/applications/sso-registration/.

# Secrets for OpenID Connect
export OIDC_RP_CLIENT_ID="Put here the Client ID"
export OIDC_RP_CLIENT_SECRET="Put here the Client Secret"

Sentry

To set up Sentry, set the endpoint with the SENTRY_DSN environment variable. To get this value go to your Sentry instance dashboard - Settings - (Select or create a project) - SDK Setup - DSN.

export SENTRY_DSN="Put here the Sentry SDK client key"

InvenioRDM

To be able to connect the platform with InvenioRDM, create a new API Token in your InvenioRDM instance (Log in - My Account - Applications - Personal access tokens - New token).

export INVENIO_API_TOKEN=<YOUR_INVENIO_API_TOKEN_HERE>
export INVENIO_SERVER_URL=<YOUR_INVENIO_SERVER_URL_HERE>
