Designing Data Trustees: A Modular Process Pattern Approach

This repository contains the supplementary material for the research paper "Designing Data Trustees: A Modular Process Pattern Approach for Data Trustees" (submitted to the International Conference on Wirtschaftsinformatik).

It provides a comprehensive collection of modular process patterns and technical documentation designed to help researchers and practitioners assemble adaptable, economically viable data trust architectures.

📦 Repository Contents

To overcome the rigid and monolithic structures of traditional data intermediaries, we decomposed complex trustee operations into reusable service components.

This repository includes:

• Process Patterns: The executable workflow models for all identified service components.
  • *.bpmn files: Standardized Business Process Model and Notation files, ready to be imported and edited in any standard BPMN modeling tool (e.g., Camunda, Signavio, bpmn.io).
  • *.svg files: High-resolution vector graphics of each process pattern for quick viewing without specialized software.
• Documentation: Extended technical descriptions and contextual applicability conditions for each modular process pattern.

📂 Structure

├── models/
│   ├── bpmn/       # Contains all process patterns in .bpmn format

└── README.md

🛠️ How to Use

• Viewing: Simply navigate to the process patterns directory to view the visual representations of the process patterns directly in your browser.
• Editing & Adapting: Download the .bpmn files from the process patterns directory. You can import these into your preferred low-code platform or BPMN editor to adapt the workflows to your specific domain requirements and legal frameworks (e.g., EU Data Act, DGA).
