Build Your Own Dataspace App: Hands-On Workshop with the Eclipse Dataspace Connector (EDC)

Join us for an exciting developer workshop where you'll get hands-on experience building your very own use case application powered by the Eclipse Dataspace Connector (EDC). Whether you're new to EDC or looking to deepen your knowledge, this workshop is designed to be both fun and practical — guiding you step-by-step as you create a real, working application.

What You'll Do

In this interactive session, you’ll dive into a prepared codebase with predefined entry points, where you’ll write the logic that brings your application to life. You’ll learn essential interaction patterns, get familiar with the EDC APIs, and discover how straightforward it can be to enable secure, sovereign data exchange between participants in a dataspace.

Your Mission

By the end of the workshop, you’ll have a functioning application that allows participants to chat with each other inside a dataspace — a playful, yet powerful way to demonstrate how data exchange can happen in a real-world scenario using EDC.

We Provide Everything You Need

• Pre-configured Dockerfiles and installation scripts (hosted and maintained by Sovity)

• A ready-to-use Graphical User Interface (GUI) to interact with

• Clear guides and instructions that walk you through each step, point out exactly where to add your code, and explain the logic behind it

Why Join?

• Hands-on experience with one of the key technologies in the data economy

• Learn by doing — no dry theory, just real code and real results

• Collaborate with peers and exchange ideas in a creative, supportive environment

• Walk away with a working app and a deeper understanding of how to build your own EDC-enabled solutions
