DECODER joins the OW2 open source code base after three years of EU-funded R&D

Designed since January 2019 as part of a Horizon 2020 European collaborative research project,
the DECODER platform continues its development within the OW2 open source code base.

Paris, May 5, 2022 – OW2, the community promoting open source software for information systems, is pleased to welcome the DECODER open source project, a result of three years of research funded under the European Horizon 2020 programme - see DECODER public deliverables provided during this period. The DECODER software project intelligence platform and its tools for DevSecOps teams are managed by the OW2 member CEA List LSL (software security and safety laboratory) based in Paris-Saclay.

DECODER provides a comprehensive open source framework for DevSecOps teams, leveraging NLP (Natural Language Processing) technologies, and cutting-edge AI (Artificial Intelligence) and machine learning techniques. Its goal is to provide greater efficiency throughout the application lifecycle, enhancing code understanding, readability, reuse, compliance and security.

OW2 presents DECODER at OSXP

The OW2 open source community invites Open Source Experience Paris attendees to discover the H2020 DECODER platform in order to accelerate their software development, with quality and security. .

Paris, November 9, 2021 - The OW2 open source community booth #C16 is showcasing the DECODER platform, a new open source toolbox for DevSecOps teams at OSXP’21, 9-10 November, Paris Palais des Congrès. This platform is an outcome of the DECODER project that gathers seven members from four European countries, including one university (Universitat Politècnica de València), one research organization (CEA List), two industrial partners (Capgemini, Sysgo), two SMEs (Technikon, Tree Technology) and OW2 as non-profit organization. It is coordinated by Technikon, with CEA List as Technical Leader and involves OW2 as dissemination leader and use case provider.. 

Thanks to its methodology and its comprehensive toolset including the DECODER PKM (Persistent Knowledge Monitor), and specific modules designed for developers, testers and maintainers, the DECODER platform can automatically analyze and document IoT and cloud computing projects, providing a deeper understanding of software codes and their changes.

The tools developed in DECODER have the potential to help developers manage the complexity of source code, as well as the complexity of artefacts such as requirements, diagrams, designs, documentation and test results,” says Armand Puccetti, CEA List Research Engineer, before adding: “Leveraging the information stored in this informal or semi-formal documents is one key goal of the DECODER project.”  

DECODER provides a comprehensive open source framework for the DevSecOps teams, leveraging technologies such as NLP (natural language processing), and state-of-the-art Artificial Intelligence and Machine Learning techniques. Its main objective is to offer more efficiency along the application lifecycle, through code understanding, readability, reusability, compliance and security. 

The DECODER project received funding from the European Union’s H2020 research and innovation programme under the grant agreement 824231.

Exploring Software Code to Understand Design Intentions

DECODER Poster October 2020
Date: October 6, 2020
Authors:  Virgile Prevosto (CEA List) and Olivier Bouzereau (OW2)
Publications: Rocking Robots, Medium

In order to ease collaboration between programmers, testers, and system operators, the DECODER platform provides deep analysis of source code repositories involved in business applications or embedded systems.

The goal of DECODER is to improve the efficiency of development, testing, verification and validation through a centralized platform. This platform is a work in progress, as it consolidates various sources of information to keep the knowledge about source code repositories, libraries and components in sync. An original feature of the project is that it considers software code as a form of natural language. Therefore, it relies on NLP (Natural Language Processing) tools and semi-formal abstract models to understand the intentions and the properties of source code.
