DataViewer is an application designed to be installed on a Cozy instance and integrated into the PLRS (Personal Learning Record Store) system.

This application allows you to visualize and manage learning data within the Cozy ecosystem, interfacing with the PLRS server for storing and retrieving Learning Records.

• A functional Cozy Stack instance
• A configured PLRS server
• Node.js and Yarn

Refer to the Cozy Stack README: https://github.com/cozy/cozy-stack/#installing-a-cozy-stack

The PLRS server is included as a submodule in this repository. First, initialize and update the submodule:

git submodule init
git submodule update

The PLRS server is located in the lrs-gateway/ directory. Follow the PLRS server README instructions or https://github.com/Prometheus-X-association/lrs-gateway

⚠️ Note: You won't need any database. Just run the equivalent of:

cd lrs-gateway
docker compose up -d app

depending on the deployment method you choose.

yarn install
yarn build
cozy-stack apps install dataviewer $PWD/build

Set up the necessary flags: When deploying at scale, it will be possible to define these flags for all instances within a context.

cozy-stack features flags '{"dataviewer.plrs": true}'
cozy-stack features flags '{"dataviewer.plrs.server.url": "<plrs_server_url>"}'

⚠️ Important: Replace <plrs_server_url> with the actual URL of your PLRS server.

Navigate to the onboarding page: http://dataviewer.cozy.localhost:8080/ (or the address corresponding to your Cozy Stack deployment)

In the browser console, you should see a URL similar to:

Webhook receiver url: http://cozy.localhost:8080/jobs/webhooks/202f8b689b9945fba29db496ff0a441a

Copy this webhook URL, it will be needed to configure your data resource on the Vision web interface.

Note: This step will be automated through the Vision API when it becomes available.

The PDC source code is available here: https://github.com/Prometheus-X-association/dataspace-connector

Follow the README file to configure it.

Once your PDC is running and linked to a Vision account:

1. Create an infrastructure offer on it
2. Link it to the webhook URL obtained during the DataViewer application onboarding
