Gaia-X Self-Descriptions

A simple proof of concept of the process to build and sign a Self-Description using the Gaia-X Compliance Service.

The main contribution of this repository is demonstrating how to programmatically build Gaia-X Self-Description documents, which are then validated by the Gaia-X Lab Compliance API. We leverage the fact that Let’s Encrypt is able to issue free certificates signed by a valid Trust Anchor, ensuring compliance without incurring extra costs.

Prerequisites

  • A Linux server with sudo access that has ports 80 and 443 exposed to the Internet.
  • A public DNS domain that points to the IP address of the previous Linux server.
  • Docker.
  • Node 18+.
  • Taskfile.

Usage

First you need to update the configuration to match your environment. Copy the file .env.default to .env and, at least, update the following variables:

Variable Description
CERTBOT_DOMAIN The domain name of your server for which you want to generate the Let's Encrypt certificate.
CERTBOT_EMAIL The email of the owner of the domain name.
RESOURCE_OPENAPI_SPEC This variable should point to an OpenAPI schema that describes the HTTP API that you want to model as a Gaia-X Resource.

Then, install the dependencies and request the certificates with the following commands:

$ npm install
$ sudo task get-certs

This will generate the certificates and store them in the certs folder. You can now build your Verifiable Credentials and submit the resulting Verifiable Presentation to the Compliance API:

$ task build-credentials

The output should be something similar to the following:
