This repository features a minimal proof of concept for the International Data Spaces (IDS) ecosystem's TRUE Connector.
The proof of concept involves deploying the Compose stack that is included in the original TRUE Connector repository. However, we deploy our own version of a data application to interact with the ECC component. This version is essentially an exact copy of the original DataApp with a minor update to verify that we can inject our own logic to fetch data assets.
Please note that the following dependencies have to be installed in the system for the scripts to work:
- Java 11
- Maven
- Git
- Docker and Docker Compose
- cURL
- Python 3
To deploy all services simply run:
make up
This will produce the following stack:
docker ps -a

You may run the following script to have the consumer fetch an artifact from the provider:
python3 get-artifact.py
INFO:root:Request payload:
{'Forward-To': 'https://ecc-provider:8889/data',
'messageType': 'ArtifactRequestMessage',
'multipart': 'form',
'requestedArtifact': 'http://w3id.org/engrd/connector/artifact/1'}
INFO:root:Response:
{'date': '2023-04-13T10:46:18.517326Z',
'description': 'Minimal proof-of-concept of the IDS TRUE Connector'}
Finally, you can run make clean to remove all side effects, including Docker containers, volumes and Java artifacts.
