Title: How Open Source Influenced Traditional Product Development

André Lemos, VP of Products, iText Software

Abstract: André explores the history of open-source development and its influence on traditional product development. In turn, he also discusses how COSS products benefit from the backing of a commercial enterprise; by employing full-time developers, keeping the product’s development on the right path, and how this feeds back into the open-source community.

He also talks about how iText uses its commercial side to drive development and benefit its wider community, and how open source can benefit from competition in the marketplace.

Title: The Evolution of Open Source into the Commercial Arena

Raf Hens, CTO, iText Software

Abstract: Raf discusses how Open Source has evolved over the years to become a force in the commercial arena. As an example, he talks about how iText began as a hobby project which transitioned into a community project, and then into a dual-licensed one.

He explores the reasons why the core iText PDF library remains open source, the differences between dual licensing and the “Open Core” model, and the importance of meeting the expectations of our development community.

Finally, he looks at the importance of structure and processes, why the “benevolent dictator” approach works in open source, and the impact of transitioning from FOSS to COSS on engineering.

Title: PDF Security: What It Is, and Why You Need It

Michaël Demey, Research Manager, iText Software

Abstract: Michaël begins by discussing the concept of securing PDFs to prevent unauthorized use or viewing, and to ensure content remains unchanged. He then talks about the ways to secure PDFs and guard the content they contain, such as with passwords, encryption, and certificates, how digital signatures work to authenticate users and detect unauthorized changes, and the concept of non-repudiation for proof of the origin, authenticity, and integrity of data.

Finally, he explores how the implementation of secure PDFs into workflows can be achieved, and what solutions are available to allow this.
