About the project

Project Name: UI-Transfer

A Complete Solution for the “User Initiated Inter-Controller and Continuous Data Transfer” Pattern

Team: Tom Haegemans, Wouter Janssens, Lauro Vanderborght, Dirk De Bot, Sander Claes

This project aims to provide a complete (i.e. legally, technically and commercially sound) solution for a problem pattern that would very commonly occur when Tim Berners-Lee’s Solid specification is adopted by organisations.

Achievements from the first phase of the DAPSI programme

In the first phase of the DAPSI programme, we were able to design a legal framework for data reuse using the Solid standard in Europe. We also implemented a proof of concept of how this framework could be used in practice.

Achievements from the second phase of the DAPSI programme

In the second phase of the DAPSI programme, we gained additional market traction and were asked to implement the framework once again in another case. We then used the insights of both cases to distil a set of reusable software artefacts to complement the legal framework and bundled everything in a toolbox called the Data Reuse Kit. At the end of the programme, we published our legal framework as a technical report, were able to grow our team with four people, got several new customers and produced an artefact that does not only benefits Digita, but the Solid community in general. The technical report is available as follows:

The Data Reuse Kit can be accessed through our website and our Github profile.



The DAPSI programme contributed greatly to the success of Digita and even Solid. This is because it gave us the resources to design and develop a component for the Solid ecosystem which has proven to be essential for the ecosystem’s adoption: a legal framework for applications in Europe
