About

Enabling a data-based circular economy via global collaboration and local production

The Fab City concept provides a promising pathway towards a more resilient and ecological mode of production and consumption. Globally connected cities and regions share data, information and know-how and collaborate on the development of physical goods in the form of Open Source Hardware, whereas the creation, repair and recycling of those physical goods and artifacts happens in the local sphere close to the place of need and by means of digital production technologies, e.g. freely accessible in Fab Labs.
While the global movement around Fab Cities, Fab Labs and the maker scene is growing, there is a digital infrastructure missing enabling a data-based circular economy on both the global and local sphere.

Connecting Fab Cities via a federated digital network

The goal of the INTERFACER project is to build this open-source digital infrastructure in the form of a federated network. Along the concept of commons-based peer production and throughout the product life cycle, the so-called Fab City OS (OS = Operating System) shall enable cities and regions to bundle, systematize and share data, information and knowledge generated in global knowledge networks and communities of practice in order to produce physical artifacts locally in a decentralized, green and resilient manner.

Fab City OS helps cities and regions to set up and run a decentralized local value creation system by matching local demand for physical artifacts represented in a store that features globally sourced designs with local production capacities (e.g. SMEs or Fab Labs) and other services (e.g. repair, adaption). It furthermore enables tracking and tracing of physical resources and thus material flows on the local level by means of digital product passport functionalities (DPP) and provides production resource planning capabilities with IoT (Internet of Things) applications in the local area.

Fab City OS connects hardware designers and producers and provides economic incentives for collaboration on a global scale. Based on distributed ledger technologies (DLTs) and a git-based versioning system of hardware design documentation, inventors and contributors may benefit financially any time physical artifacts based on this documentation will be sold in a Fab City. Any contribution and enhancement will be tracked and value that is captured be distributed among the people involved in the design process. Fab City OS empowers citizens to participate in value creation and sustainably consume by giving them full access to the documentation and thus control over the products they may buy, build, adapt, use or repair.

Building the digital infrastructure to run a Fab City

In the EU EFRE-funded project INTERFACER, four partners teamed up to develop, test, publish and run the Fab City OS and collaborate on related issues, e.g. promoting circular design or improving the Open Source Hardware tool chain. Existing open source solutions and software applications will be further developed and systematically integrated. The focus is on the identification, definition and design of interfaces between systems, networks and physical artifacts, from which the project title INTERFACER is derived. Helmut-Schmidt-University leads the consortium with a research-driven approach and strong focus on value co-creation, bottom-up economics and open source hardware. Fab City Hamburg e. V. is the perfect use case and thus partner to develop the user interfaces and create a unique user experience. Dyne.org foundation has a great track record on building open source software in Europe for decades which greatly benefits the project. Finally, HIWW provides expertise to the consortium in the field of innovation and knowledge management.

Vision

Our vision is to promote a green, resilient, and digitally-based mode of production and consumption that enables the greatest possible sovereignty, empowerment and participation of citizens all over the world.
We want to help Fab Cities to produce everything they consume by 2054 on the basis of collaboratively developed and globally shared data in the commons.

Mission

The need to reorganize globalized value creation and production systems and to establish sustainable and synergetic production processes worldwide is the starting point for the INTERFACER project. The goal is the development, initial application and distribution of an open source software system called Fab City OS (OS = Operating System) which can be implemented as a software stack along the value chain at the respective entities of the global network, e.g. Fab Cities, Fab Labs to build up and run a local and yet globally connected value creation system.

Key Principles

We strongly believe in the power of Open Source and thus apply corresponding licensing regimes to all of our software and hardware developments and applications. As a result, a digital commons is created - a public, non-exclusive good. Another key concept is federation in the sense that we build a digital infrastructure that can be hosted individually and independently by a Fab City while being able to connect and exchange data with other Fab Cities. Finally, we make use of distributed ledger technologies (DLTs) and crypto functions to enable secure transactions among the network.

Research & Development

The path to a digitally based circular economy with open source software

While the development of Fab City OS is at the heart of the INTERFACER project, we also engage in related issues that can make an impact on the dissemination of Open Source (Hardware) and circular economy practices. Below, we will introduce a selection of projects we work on.

Fab City OS - Software Kit

The Fab City Software Kit enables Fab Cities to build a community and share knowledge within their city and with others. It comprises a set of open source software components bundled and packed to be installed on a local instance by a Fab City with features that enable local community building, communication and collaboration.

Fab City OS - Core

Fab City OS is a central component of the digital infrastructure of a Fab City and can be easily installed and used by users as part of the Fab City Software Kit. It enables the efficient production and marketing of Open Source Hardware at all levels of the value chain of distributed production. The technological basis is Reflow OS majorly developed by Dyne.org in a EU-funded project which enables modeling of economic exchanges to promote trustworthy circularity at a generic level. We focus this featureset on workflows related to Open Source Hardware and production workflows. Part of this backbone is also a digital product passport (DPP) with two dimensions, namely to track and trace material and design flows. Fab City OS will allow designers to exchange and contribute to each other’s designs and bring manufacturing and design closer together with a set of suitable user interfaces. The software development will also be accompanied by a policy and user research process resulting in an economic framework.

Open Source Software for Open Source Hardware

Key to a seamless workflow from digital files to physical artifacts is a fully functional open source tool chain from hardware design and development over engineering to production. We address current shortcomings in this realm by developing a software prototype to automate the documentation process of an Open Source Hardware Project which has the potential to leapfrog collaborative development. Besides, we will develop a set of OS tools for project management of hardware projects and build a foundation that promotes the development of Open Source Software for Open Source Hardware development.

Outreach Activities

With different formats and approaches, we reach out to potential users, facilitators and stakeholders both on the local level within Fab City Hamburg as well as in the global context via the Fab City Foundation to raise awareness on the project, to gather expert insights and to build up user and expert communities. Together with these communities, we want to elaborate circular design principles and innovation best practices that are appropriate to spark inventive behavior among citizens globally and thus foster the dissemination and adoption of Fab City OS.
