Beacon v2.x

This repository is an implementation of the Beacon v2.0 Model and contains:

• The (Python 3.9+) source code for beacon,
• A MongoDB database with sample data to demo the capabilities of the Beacon API.
• AAI and LS-AAI integrated.

Frontend usage instructions

Managing AAI-LSAAI permissions

To give the right permissions for AAI you will need to set the permissions of the users inside permissions folder, within the public_datasets.yml, registered_datasets.yml, controlled_datasets.yml files, or run the beacon admin page that allows you to manage all the permissions in a friendly way and no need to open .yml files. Just start the UI, that will run in http://localhost:8010, by executing this command from the deploy folder after the containers are up and running:

docker exec beacon-permissions bash permissions/permissions-ui/start.sh

Note: To make the permissions ui run, create an .env file inside permissions/permissions-uiweb folder and add the next variables with the exact same names:

SECRET_KEY="your_permissions_ui_secret_key"
OIDC_RP_CLIENT_ID='your_client_id'
OIDC_RP_CLIENT_SECRET='your_client_secret'

Please, bear in mind that the name of the user has to be the same that you used when creating the user in LS or in IDP, whatever the AAI method you are working with. To give a user a certain type of response for their queries, please modify this file response_type.yml adding the maximum type of response you want to allow every user.

Also, you will need to edit the file conf.py and introduce the domain where your keycloak is being hosted inside idp_url.

Also, inside the folder permissions, before building your permissions container, you will need to create an .env file for each idp provider (e.g. lsaai.env) inside idp_providers folder you want the beacon to allow, and add the next variables (exactly named the same for each idp provider you add, see example.txt for an example):

CLIENT_ID=example_id
CLIENT_SECRET=example_secret
USER_INFO='https://example.com/userinfo'
INTROSPECTION='https://example.com/introspect'
ISSUER='https://example.com/issuer'
JWKS_URL='https://example.com/certs'

When you have your access token, pass it in a header with Authorization: Bearer in your POST request to get your answers. This token works coming from either from LS AAI or from keycloak (idp container).

Handling CORS

To avoid CORS using beacon and the frontend or a third-party authorization site like Keycloak, you will have to include all these URLs inside main.py, including them in the CORS middleware and CORS routes lists:

middlewares=[web.normalize_path_middleware(), middlewares.error_middleware, cors_middleware(origins=["your_URL"...

    for route in list(beacon.router.routes()):
        cors.add(route, {
        "your_URL":
            aiohttp_cors.ResourceOptions(allow_credentials=True,
            expose_headers="*",
            allow_methods=("POST", "PATCH", "GET", "OPTIONS"),
            allow_headers=DEFAULT_ALLOW_HEADERS),
