Perennial DToU, on SoLiD

This repo is a meta-repo for the work about Perennial Semantic Data Terms of Use (DToU, or psDToU), originally reported in our WWW 2024 paper.

The work is being continuously improved. See here if you want to see the repo for the WWW 2024 paper.

Try from this repo's Pages if you encounter any unexpected rendering of resources (e.g. DToU Spec).

Introductory Resources

If you want to understand what is DToU, and how it differs from other approaches (e.g. ODRL), the following would be of interest to you.

Overview

• 3-min Video Intro
• Poster

In-practice or in-details

• Demo apps for DToU + Solid: Demo apps for SoSy2026 Authz Session
  • You need a compatible Solid service -- see below
• DToU Spec: specification of the DToU policy language
• Paper: DOI 10.1145/3589334.3645631
  • arxiv: 2403.07587

Repo and Code

If you want to try it in practice, host your service, or dig into details, see below.

• DToU lang: The repo for the DToU language, containing the reasoner (the core of the DToU policy engine), mainly N3 rules, and the basic rules for the language (and example rules)
• CSS with DToU: The repo for the modified CSS (Community Solid Server) where the DToU engine is integrated with
  • The DToU engine uses the same reasoner (N3 rules) as the DToU reasoner repo above
• DToU Demo App: The repo for the demo App for demonstrating the integration
  • It also contains the benchmark scripts
