OW2 is 15 years old, and things are moving: OW2's new CEO, Pierre-Yves Gibello, shares this session with Cédric Thomas, the CEO who started OW2 from scratch, to open OW2Con'22. What's next?
Starting a new open source project is the easy part. Building a skilled community to strengthen the project while making it a professionally adopted, industry-grade open source software is much more challenging. It requires a sustainable business model that balances the spirit of open source with economic realities. And what works in the early years of a project doesn’t necessarily work forever: finding the right balance is a never-ending journey. Let’s try and understand what works, what doesn’t.
It is a common strategy to start an open source solution without external contribution and governance. But at one point, your ecosystem will need an open governance in order to invest in the project and contribute. Then, where do you start? Strategic governance, technical governance, road-map, legal compliance, intellectual property and business model are hot topics to address. In this presentation, we will see together how to track the work to be done, and start the opening process to have a clear separation between the company and the open source project.

Portugal is proud to be at the forefront of progress and adoption of the latest technological advantages, but in relation to Open Source, after a late start, it is now starting to create new business opportunities.
ESOP - the Open Source Business Alliance for Portugal, has worked with the business community and the Portuguese Government since its creation in 2007, to create a dynamic market where Open Source technologies are well accepted and compete in equal terms.
In this talk I'll explain some of the opportunities and challenges a newcomer to the Portuguese market might expect.
This talk shows how the Standard for Public Code can help you collaborate with public organizations all across the world.
Digital Sovereignty is a tough subject for the Collaboration software industry, which is heavily dominated by the large US cloud providers Microsoft & Google. This talk will address the importance for Europe to not give up this space, the challenges that lay ahead, the pitfalls we should avoid, the success that do exist, how Open Source matters to allow the industry to work better together to really challenge the status quo.
The EU is on its way to adopting legislation on artificial intelligence. Transparency plays a major role in this. But how exactly should this transparency be designed and what role does Free Software play? The talk will give an insight into the current state of the debate and what chances there are that provisions for Free Software will be included in the legislation.
What is Rocket.Chat? Rocket.Chat is a fully customizable communications platform for organizations with high standards of data protection. It enables real-time conversations between colleagues, with other companies or with your customers, regardless of how they connect with you.
Rocket.Chat has grown beyond team.chat, the chat, you most likely know as: Teams, Slack, Mattermost or similar communication tool, each has channels, threads and discussions. With this growth our team kept closely engaged with our Open Source Community. This community is the motor to grow and prosper together, allowing our engineering team to be on the edge of technology providing the finest integrated solutions together with community’ eyes and hands.
Conversations make us unique. They’re the very thing that makes humans, humans. They’re how we connect, bond, exchange information and work better together.
Unfortunately, the technology that was meant to bring us closer together, managed to set us apart. It focused on the benefit of a select few rather than that of each of us. It limited what we can and cannot do.
You’re allowed to talk. As long as everyone uses the same tool. As long as you’re ok completely waiving your rights to data privacy, security and ownership.
Enough.
These are our conversations. It’s time to make things right. Time to focus on the better good. We’re meant to connect, bond and work together with whoever we need to - on our own terms.
It’s time to own our conversations. Just like it was always meant to be. Rocket.Chat
For about a year Omnichannel has been integrated with all chats, this is the way to communicate with almost every communication medium you can imagine like: Telegram, Facebook, Messenger, WhatsApp, WeChat, SMS, Email, and so on.
Recently Voip and the Matrix protocol were added to this mix allowing power users to seamlessly switch communication between all the contacts directly in their preferred device. Omnichannel is about removing friction for your customers, and allowing business to happen wherever your customer prefers to communicate, it has a Live Chat that can easy integrate in any web based application.
Let every conversation flow - without compromise Own your data, customize anything, integrate everything.
Customizations we call in.app.chat, the playground where lots of apps meet a robust realtime api and the new UIkit allows developers to do all this magic with the best interoperability and security you're already used to.
Some of the magic is summed up here:
- Authentication: LDAP, Saml, oAuth2/OIDC
- Voip and email connection (the old world)
- Matrix WebRTC with federation (new deal technology)
- Robust rest and realtime api that integrate with about anything -- Webhook integrations and bots that allow AI/NLP -- App engine that allows for full integration -- UIKit that allows UI extensions and new type of integrations and interactions -- Interoperability a must have these days -- Security.
Anyone who has worked in software development knows that some parts of code are repetitive and boring to write. It is precisely to avoid this inconvenience that Telosys (OW2 project) was created.
During this talk you'll discover how simple it is to use this code generator and how it can save you a lot of work. Telosys is usable to generate any kind of language (with any framework).
A short demo will show how to generate a Python web application.
KNOWAGE, the enterprise-level suite for analytics and business intelligence available on OW2 Marketplace, is constantly evolving to help end users to look more clearly into their data and support them in the decision making process in an increasingly intuitive way. KNOWAGE evolution in 2022 mainly focuses on: new data preparation module and data federation in self-service process, augmented analytics to support every end-user touch point and provide automatic insights, usability and performance for a new effective UI, a core offering as SaaS ABI solution.
Lutece Core 7 was released last year by the City of Paris' dev team, offering new features and a cleaner and lighter code. All digital services can now benefit from it and from a larger and larger shelf filled with source code, new business packs packages arise to facilitate their adoption by the growing community and peers.
Since 2001, OCS Inventory has been looking to make hardware and software inventory of computers more efficient. The open-source software includes the package deployment feature, in order not to control, but to ensure uniformity of the software environments present on the network.
Cover the progress and new features developed in XWiki since last year's OW2Con conference.
On May 1, 2021, the bintray server was closed. The dependencies of our open source softwares Centreon-Engine and Centreon-Broker were no longer accessible. Impossible to compile a new version. How to best manage dependencies to external projects in an open source product. Are there sustainable, risk-free solutions or is it only utopia?
Imixs-Office-Workflow is a production ready easy to use Business Process Management Suite. It enables you to digitize and organize documents and business workflows in a fast, flexible and transparent way.
LemonLDAP::NG is a WebSSO, Access Management and Identity Federation free software. Years after years, new features are added to ease the integration with applications and improve the support of standards like OpenID Connect.
French Gendarmerie Nationale is a major LemonLDAP::NG contributor and an advanced user since 2004. More than 10 WebSSO instances have been deployed and migrated to LL::NG 2.0. Those platforms are declined into different flavours to afford specific services and meet particular needs. To achieve this, it requires advanced functionalities or features that have been implemented and appended to LemonLDAP::NG since the first 2.0 release in 2018. This presentation aims to describe and explain some of those advanced functionalities/features that can only be found in LemonLDAP::NG and nowhere else!
This speech aims to highlight the benefits and strengths of open source solutions for enterprises and public administrations willing to gain relevant insights from their data. Different use cases will be presented in which KNOWAGE, the open source suite for analytics and business intelligence, enabled effective data analysis helping to achieve data-driven decisions.
Trends in mobile app technologies
With estimations of over 230 billion mobile apps downloaded last year, a figure growing year by year, mobile apps are projected to generate more than 613 billion USD in revenues in 2025. This promising estimation will be supported by the upcoming development trends driven by cutting-edge technologies that enable new services and products for a demanding audience. The everlasting discussion about native, web, and hybrid technologies continues. More powerful devices, fastest communications, immersive technologies, and new architectural paradigms (the so-called, Web3) complement new choices in mobile development. Light apps for seamless user experiences, Progressive Web Applications for universal access, distributed applications for increased robustness are only some examples of the new possibilities today.
Everybody talks about Web3, but no one really knows what this word actually means. The certainty is that a big change is coming. Blockchains are an interesting technology, but how do we integrate them in our daily life applications? How do we deal with interoperability? Data ownership? New architectures?
With the examples of Verifiable Credentials, Distributed IDentity, Solid web standards and an opening on complementarity with Distributed Ledger technologies, we will present all the work we do on this matter at Startin'blox and the state-of-the-art technical trends beyond Web3.

The number of devices on which users cannot run Free Software is exponentially increasing. The consequence is an increased loss of control over users’ technology.
Device neutrality is the policy concept that users should have the right of non- discrimination of the services and software they use, based on platform control by hardware vendors, manufacturers and service providers. It is a concept that involves the fair and non-discriminatory use of Free Software in devices. The talk will explain why Free Software is fundamental to implement Device Neutrality.
Free and open source license detection in source and binary code is still evolving at fast pace. License detection is essential to get licensing right in an automated way as we are consuming more and more FOSS code packages to build rich systems and applications.
This session will present the latest techniques.
IT transformation : moving applications to the cloud involves redesigning the architecture and making different choices for some components of the applications.
This is particularly true for Databases, and can lead to a lot of work and uncertainties.
This presentation is a return of experience of a particular use case that prepares & facilitates migration to the Cloud
LibreOffice was announced in 2010 as a desktop productivity software for Windows, macOS and Linux. Since 2011, it has evolved from a single desktop product to a technology platform supporting applications for the desktop, the cloud and mobile. All products share the same engine, which provides superior consistency. The goal of the presentation is to present the different stages of this evolution.
from opportunity study based on Orange France uses cases to industrialization and support of projects (training and video tuto) also a quick highlight of partners which helped us at specific moments on this project
Online collaborative work is growing in popularity today. Working remotely as a team also involves collaborating on documents. ONLYOFFICE Docs offers an online editor for text documents, spreadsheets, presentations, and forms.

In this presentation we talk about why we use Lisp, and what it has done for us as a small open source organization. We talk about the power of the REPL, the power of SEXP, and more.
Systems (e.g., Hadoop, Mysql, Hive) contain a vast number of configuration parameters that control the performance of the system. However, it is a challenging task to tune the parameters, as there are more than hundreds of parameters and the best parameters are different for different workloads. To solve this problems, we design an AI-based automatic parameter tuning system (named A-Tune). The experimental results show that the performance of mysql improves 30%-40%.
Nowadays a lot of tools exist to ease dependency management helping you to keep your dependencies up to date and secure. But most of those tools lack accuracy leading to noise for development team. This session will present a demonstration of FASTEN tool that demonstrate how the combination of several data sources and call graph can lead to a more accurate dependency management assistant.
More and more organizations are picking up the DevOps practices and controlling their infrastructure using code - following the Infrastructure as Code (IaC) principles. However, every code, including IaC, needs testing, otherwise stakeholders risk security issues with everything that comes along. To this end, the European Union's Horizon 2020 project - PIACERE - is proposing DevSecOps methodology focusing on security and extensive testing. In this talk, I focus on the dynamic testing approaches marketed as the PIACERE Canary Sandbox Environment (CSE). The CSE extends open source software, contributing back to the ecosystem, and allows to test the IaC in a controlled environment.
The talk will describe the MORPHEMIC open source components and the MORPHEMIC implementation integrated as a pre-processor for the existing MELODIC platform extending its deployment and adaptation capabilities beyond the multicloud and cross-cloud to the edge, 5G, and fog. The talk will then detail the open source strategy for the exploitation of the project results.

Microsoft recently underwent a transformation in its relationship with open source. To keep up with this transformation, its polices, procedures, and tools needed to grow exponentially. In this talk, Justin will walk through the organizational, legal, and cultural changes that enabled Microsoft to create reliable and predictable open source engagement at scale.
Fully embracing Open Source Software means to go beyond simply using it – it means to become an active member of the Open Source community. But how do we get there as a big automotive company? At Mercedes-Benz, we decided that if we are going to take Open Source seriously, this needs to become deeply ingrained in the company’s “DNA”, away from a strict “we develop our own code” attitude.
This is why we created the Mercedes-Benz FOSS Manifesto. It is a set of guidelines and core values which sends our employees on their Open Source mission, knowing well that they are fully supported by the company. It is now a key pillar in how we become part of the Open Source movement, and – in the spirit of Open Source – we would like to share it with you.
In this talk, I will present our Mercedes-Benz FOSS Manifesto and the therein contained principles. Attendees will learn how these principles can modernize and transform an IT organization to drive forward a cultural change towards Open Source which will profoundly impact the way in which software is developed at corporate level.
Open source is eating the world and academic institutions cannot escape from that. With several American universities joining the ever growing list of institutions explicitly promoting open source through offices dedicated to fostering Open Work, we will share some initial experiences, lessons learned, and some insights into where we think open source in academia is headed. In this short talk, we will tell a story about how “Open” in academia goes far beyond source code, and the way faculty create, distribute, and collaborate on their work varies greatly. This talk will only cover the tip of the iceberg of Open Work in academia but will provide attendees an introduction to this great world that we are discovering ourselves.
As the software engineering field gets more mature, properly managing open source software and culture within organisations has become more important and needed than ever. In this context, the Good Governance Initiative offers a much-needed set of actionnable guidelines to hep frame, build and develop OSPOs within any type of organisation.
During this roundtable, we will discuss OSPOs, their role and duties, and share experience and best practices with our panelists.
