While financing infrastructure and its maintenance is extremely important (no questions asked), in this talk we want to explore why a diverse funding landscape that also allows for supporting people and groups with new ideas, that have been under the radar before, can only be incredibly valuable to the field of open source.\n\nHow can we use existing funding structures, bend and twist them to meet the real needs of communities? How can we make them more useful to projects and people who are not typically the recipients of their money? We want to talk about how to build support infrastructure that allows us to fund in ways that bring more diversity, more joy in experimenting, more novel ideas and more inclusivity to our communities - and we want to talk about how to do this in a sustainable way.\n\nWith the Prototype Fund we have funded almost 400 projects by and for the civil society in the past eight years. This has taught us a thing or two about the different wants and needs of grantees, about what they value in funders and the importance of flexibility when funding inividuals and their innovative ideas.\n\nThis talk is a call to government institutions, funders and other organisations with the power to distribute money to join forces, break down the barriers that might come with their traditional funding models and create a vibrant network of small, diverse and lightweight funds that meet the needs of different communities. It is an invitation to communities to come together and share their needs in order to help build structures that can actually support their work.", "recording_license": "", "do_not_record": false, "persons": [{"code": "EVVFVB", "name": "Patricia Leu, Prototype Fund", "avatar": "https://pretalx.ow2.org/media/avatars/EVVFVB_Mcsjpye.webp", "biography": "Patricia is co-director at the German public funding programme Prototype Fund.

By reusing and contributing to open-source projects initiated by public administrations, we can create a robust ecosystem that benefits both the public and private sectors. This talk will explore how reusing public projects can lead to shared governance and a thriving open-source software (OSS) ecosystem.\n\nKey Points:\n**Decidim Case Study:**\nDecidim is an open-source platform designed for participatory democracy, enabling citizens to engage in decision-making processes. The project is a result of public investment from the city of Barcelona. It is now a vibrant open source ecosystems with more than 10 integrators, 150 contributors and instances running all around the Globe.\n\n**The sovereign workspace opportunity \ud83c\uddea\ud83c\uddfa for the FLOSS ecosystem**\nWith La Suite Num\u00e9rique and OpenDesk we have the opportunity to create a credible alternative to internet giants' solutions at a moment in history where it is the crucial. If states cities and open source companies work together we'll get there faster and sooner.\n \n**From Reusing to Contributing to Shared Governance:**\nOften we see public entities adopting open source software, most of the time relationship with software editors go great but sometimes it gets harder. The path to true sovereignty is the one that leads to autonomy meaning, operating their infrastructure, contributing to the code and have a say on the roadmap. For large organization as budgets margins becomes thinner the licence models becomes less financially viable and slows down adoption of open source solutions. \nSo what if we do it the other way around, public organization as editors, and businesses as reusers and contributors. We'll discuss the potential benefits of this approach.\n\nConclusion:\nBy reusing and contributing to public open-source projects, we can build a strong foundation for digital commons that benefits everyone.

In the first edition of this laboratory, we are creating a dataset of misinformation online, involving people to collect untrustworthy news, to annotate the content of news, and discuss how this dataset can be used to shape a software that supports them in their search of information.", "description": "Collecting data is a crucial step for the development of AI tools. The most common approach to data creation is scraping contents and behaviours of users-generated contents mainly online, and use crowdsourcing platforms or relatives (colleagues, students, and so on) for the annotation. However, recently, some scholars advanced some alternative methods that involve people at different steps and levels during AI-based service development (Delgado et al., 2023). Following their proposal, we designed the Citizen-Dataset Lab, a laboratory with the purpose of creating datasets with people in order to involve them in the process of dataset creation used for training models, and guarantee that their opinions/decisions are embedded in the annotated dataset. Indeed, current technology is designed and delivered by W.E.I.R.D. researchers without consulting the real needs of citizens or including perspectives coming from disadvantaged communities (Dignum, 2023).\nThe design of our lab is based on 5 principles: (1) Ensure diversity in dataset creation and annotation; (2) Promote participation, empowering people to decide which are the contents that must be included in a dataset, and explaining to them how technologies use data; (3) Consider subjectivities in the creation of schema of annotation and guidelines; (4) Democratize technologies co-shaping the service with people, collecting impressions about the annotation process and discussing the potential uses of the developed resource; and (5) Embrace Open Source. In fact, datasets and technologies resulting from this laboratory will be open source and available to the community. \nThe first edition of Citizen-Dataset Lab (February-May) focuses on misinformation. The spreading of misinformation is strongly related with the growth of ideological polarization in the EU (Vasist et al., 2024). Communities of people exposed to opposed media diets become ever more conflictive in the online conversation, with worrying effects in the real world. Therefore, we believe that machines should not classify news as true or false, but support people in grasping the complexity of our media environment and in understanding other views of the world. In this context, Citizen-Dataset Lab will help us to shape the new features of  Debunker-Assistant, an open source product for fighting misinformation (Capozzi-Lupi et al., 2023), building a multilingual dataset to make Debunker-Assistant better and fairer in supporting people against misinformation.\n\nReferences:\nDelgado, F., Yang, S., Madaio, M., & Yang, Q.
