Michiel Leenaars, Dir. of Strategy, NLNet

Technology is everywhere, and is reshaping how we live, work, (get) entertain(ed), learn and create. But not all technology is equal, nor beneficial. As societies we have the choice to let ourselves be dragged around by the maelstrom of venture capital and its continuous flood of (wannabe) big tech and unicorns that like to move fast and break things or to use the potential of digital commons to empower everyone.

NLnet Foundation is one of the most active grantmakers in the field of the open internet and of technology commons. NLnet is a public benefit organisation that was instrumental in taking the internet out of the United States and bringing it to Europe in the eighties, making it one of the oldest grant making philanthropies in the space of digital commons in the world altogether. Together with a growing coalition of partners, and supported by donations from individuals, foundations, public sector organisations, companies and institutions like the European Commission, it has been a strong advocate for building a free and open technology stack from top to bottom. NLnet has been an active proponent of the European Next Generation Internet initiative, in particular through the various NGI Zero programmes.

In this talk, Michiel Leenaars (director of strategy at NLnet) will take a quick recap of history and give a high level overview of the digital commons landscape from the point of view of a small and flat country partially below sea level. He will also give an update on the hundreds of recent and ongoing efforts funded by NLnet creating advanced FOSS building blocks   from open hardware e-ink screens and mobile networks to social media tools, from video conferencing tools to compartementalised operating systems and secure digital payment methods.

Michiel Leenaars, Dir. of Strategy, NLNet

Michiel Leenaars (1972, Netherlands) is Director of Strategy at [NLnet](https://nlnet.nl). He is responsible for defining and initating short term and long term policies and managing strategic activities within the NLnet foundation, and acts as its spokesperson to the press and society. He currently also leads [NGIZero](https://nlnet.nl/NGI0), a family of research programmes including [NGI0 Entrust](https://nlnet.nl/entrust) and [NGI0 Core](https://nlnet.nl/core), part of the [Next Generation Internet](https://ngi.eu) initiative. He joined the management team of NLnet in 2007. He has a background in Physics at [Technische Universiteit Eindhoven](http://www.tue.nl) and Theory and history of literature/Visual and verbal communication at [Tilburg University](http://www.uvt.nl).

Alexis Kauffmann, Ministry of Education

"Supporting the development of digital commons" is a strong axis of the new Digital Strategy for Education 2023-2027 of the French Ministry of National Education, which uses a lot of open source software but also contributes to it.

Sovereign and sustainable, the Forge of Digital Commons is one of the projects of this strategy.

France has nearly a million teachers. Among them, there are teachers developing Open Source softwares but there are also more and more teachers using text format (markdown, LaTeX...) to create and share educational content. Yesterday all these projects were scattered over multiple forges including Microsoft's GitHub which is difficult to trust in the long term. Hhosted and managed by the ministry, the "Forge of Digital Educational Commons" project aims to pool all these projects on a dedicated GitLab instance and invite the school community to participate.

Julien Paris

A customizable open source widget to visualize and edit open datasets, without any other backend than Github or Gitlab.

Imagine you are a business, a public institution, or non-profit organization and you regularly produce datasets you would like to share and to valorize ; you produce datasets but you would like to make them become true digital commons. It could be complicated for you to share those data on your website in a pleasant and intuitive way, and it could be even more complicated to invite your community to contribute to it : either you don't have enough money to invest in a proprietary solution, or you lack time or skills to do so...

Datami is a 100% open source project allowing you to generate and configure datavisualization widgets on top of open datasets, but also to make possible for anyone to contribute to them.

With Datami you can visualize open datasets as interactive cards, tables, maps or graphs. Datami also allows you to open your datasets to contributions - without asking users to create any account - but keeping the dataset producers' ability to moderate such contributions .

Datami uses Github or Gitlab as its "backend", so all the moderation tools you will need to curate contributions already exist thanks to Github's or Gitlab's API !

As Datami works as a web component you can integrate Datami in any website, and fine-tune its configuration directly in the page's html.

Datami is 100% free to use : the source code can be deployed once, but any widget calling the deployed code can be configured independently.

Datami was one of the laureates of the "France Relance 2022" open call from the French National Agency for the Cohesion of Territories (ANCT), and was developed by the french digital cooperative multi.

☕ Coffee break



Clément Aubin, XWiki

XWiki is a FOSS knowledge management solution, and a direct alternative to the Confluence, the wiki part of the Atlassian software suite, along with Jira or Bitbucket. XWiki and Confluence share similarities in their approach, including an extension mechanism and the possibility to write macros in wiki pages, which enables users to create dynamic contents.

Today, following changes in Atlassian's policy when it comes to handling on-premise licenses [1], companies are looking to migrate away from Confluence to limit lock-in and to take back ownership on their data. However, migrating from such complex systems comes with its own set of challenges, both when it comes to the financing of migration tools and the implementation of technical alternatives to functionalities in proprietary software.

In this talk, we will dive into some of the technical aspects that make a migration from complex proprietary tools difficult. We will also look into how we chose to build and finance the development of Open Source migration solutions to make the switch from Confluence to XWiki.

Christophe Maudoux, Gendarmerie Nationale

LemonLDAP::NG is a free open source full AAA WebSSO solution. It provides global Authentication (Single Sign-On), Authorization (access rules) and Accounting: (access logs).

In cloud environments or  DevOps  architectures, applications may require other applications API. It means that a web application may need to request some other web applications on behalf of the authenticated users. LemonLDAP::NG provides three ways to do this:

  • the Ugly that consists in providing SSO cookie to all protected applications. It is an unsecured method because the SSO cookie can be caught and used everywhere, every time by everyone! NOT RECOMMENDED solution.
  • the Bad with the SecureToken Handler. This approach is deprecated. Should be used for specific use cases only.
  • and the Good one with the ServiceToken Handler. Since 2.0 version, LL::NG provides a better way to protect API by using limited scope tokens aka ServiceTokens.

I will explain the ServiceToken Handler mechanism and how to implement it during this presentation...

Konrad Wawruch, 7bulls, Geir Horn, Univ. of Oslo

Persistent applications will experience variable demands and workloads, and Cloud resources may mitigate performance problems by allowing the necessary resources to be temporarily rented as needed. Cloud deployment decisions must consider not only the best suited providers but also the possibility to use beneficially hardware accelerators like GPUs and FPGAs should these be useful for the application and improve its performance. Since additional application resources may be needed at any time in response to the changed workload, or as a function of the data processed by the application, automated application management is desirable. This talk will cover the versatile MORPHEMIC platform capable of managing and optimizing the application over its lifetime using forecasting to predict and anticipate changes in the execution environment and proactively provide the Cloud resources timely to the application. Additionally, MORPHEMIC can deploy polymorphic application components to the hardware resources best apt for the application tasks at hand. Examples from real world applications will be given to show the benefits of the approach.

Anthony Harrison

There is an increasing awareness that Software Bill of Materials (SBOM) will be a key artefact in improving software security and resilience. However, an SBOM is only as good as the data which is contained within it. Recently there has been a lot of discussion about what makes a good SBOM and this session will attempt to define this and identify the key parts of the SBOM which the community can help curate and improve to ensure that the benefits of providing and using SBOMs are realised. This session will include a number of practical examples to show what can be revealed when the quality of the data is improved.

Krystian Podemski, PrestaShop

Some of the challenges that open source projects face are organizing member contributions and increasing community involvement. During this talk, we will show you how PrestaShop, one of the leading open source e-commerce software platforms, addressed these challenges and strengthened its community in the last few years.

You will understand how the PrestaShop project evolved in recent years, and how new communication channels helped project members be better informed and get better involved. To go further, the project is working with contributors in a live environment, so discussions and communication can be kept with the community. We will show you how this has eased communication between members.

A new open source team has been put in place. You will better comprehend the influence it has had on the separation of the project from the company. You will also learn, through short use cases and examples, about the maturity of the PrestaShop project and how community pull requests more than doubled in 5 years. In the future, the project would like to open decision-making to the community, which will be discussed during the presentation.

Samir Saidani, Babel.coop

Free and open-source licenses are the standard way to make software a digital common good. A digital common good might be governed in various ways depending on the political awareness of the authors. The power to commit changes to the code is usually held by a few hands. Changing the governance is hard: the energy cost to maintain and develop the forked software acts as a barrier to change. We propose a social technology to secure the democratic governance of a digital common. A Democratic Common is a common governed in a democratic way through a constitution. The constitution itself is a common good. The constitution guarantees the sovereignty of the community over the common.  The constitution protects the fundamental rights and freedoms of the members of the community. Democratic common governance is based on the rule of law, like any democracy: everything is authorized unless a rule states otherwise. The organization of the common is structured by roles and circles created and destroyed dynamically according to the needs of the common. The common decision process is a battle-field tested governance process, involving the collective intelligence of stakeholders to produce the rules of the common. Babel.coop is a democratic common run by the Babel.coop Constitution, which has been successfully used for a few years in our community. The Babel.coop Constitution will be released into the public domain.

Jehan Monnier, Belledonne Communications

The Linphone project is an open source solution that was first released in 2001. It started as a personal project done on spare time and it is now a sustainable company employing 20 people (15 of them being software developers). We believe that employing open source software developers is the best way to pay them for their contribution to the open source ecosystem.

We are often asked how an open source company can make money and grow on the long term. We rely on three different sources of income:

  • corporate customers, by selling our technology to third parties who wish to integrate it to build their own products. Our revenue has been progressively increased thanks to a business model based on three types of income: licensing, support, and developments on demand. Third party companies are willing to finance the development of your great open source technology if you ask them to!
  • public subventions, via the response to a call for expressions of interest and the use of research tax credit (CIR)
  • end-users, by selling our solution in a SaaS mode to companies who wish to use it « as is » for their internal needs. This talk will highlight why and how we are reworking our business model with the aim of wearing two hats: technology provider and software editor. This will allow us to obtain a new source of income, that we hope to be recurrent.

Martin Alvarez-Espinar, Huawei, W3C

Every town is singular and has a fascinating history (and many stories) behind it. Undoubtedly, digital transformation helps preserve culture and (material and immaterial) heritage and allows us to expose these local stories and hidden gems to the current and future generations. Still, not all communities have the resources or capabilities to digitize their most precious touristic, natural, or cultural assets. To overcome this worldwide challenge, we have created 'Heritage in...', a low-code methodology and open-source tools, to support local communities in promoting their famous and unknown heritage through open data resources and collaborative tools.

This talk presents a non-commercial methodology and tools developed under the OW2 Quick App Initiative that enables rapid development and release of new light applications (Progressive Web Applications and Quick Apps) to digitize, promote and enrich the local heritage of any town worldwide. The project has been tested with several real-world implementations that make the most of the public (and open-licensed) assets, public knowledge, and open-source tools. In less than one hour, we can implement new appealing use cases. No strong IT skills are required; only a basic understanding of Git and web technologies.
