Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.
An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format
SysON was presented during the Vendor Roadmaps and Implementation Status session of the MBSE Workshop held as part of the INCOSE International Workshop 2025, in Seville, Spain, on February 1, 2025.
We're thrilled to share that we've already made significant progress toward our goals!
As demonstrated in the quick demo, SysON is up and running—packed with powerful features and designed with a strong focus on user experience.
The project is on the right track and is already generating considerable interest.

SysML was created in 2005 as a standard for model-based systems engineering (MBSE) to elevate the role of models as primary tools for communication and documentation.
With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysML 2.0 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.
SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.
This will be achieved through three means: the support of the SysML 2.0 standard, the use of state-of-the-art web technologies, and an open-source approach.

Modding Sonic Generations is practically a rite of passage for Sonic fans. From importing Sonic Unleashed levels to playing as Shadow or Metal Sonic, the community has kept this game alive for over a decade. However, it’s incredibly frustrating when you’ve spent an hour downloading files only to have the game crash or simply ignore your mods.
Some total conversion mods (like The Hedgehog Project ) redirect your save file to a different folder to prevent corruption. If your game crashes immediately upon loading a save, try toggling the setting in HMM. Run as Administrator

Obeo is also preparing a secure cloud-based offering to provide SysON as a fully hosted SaaS solution, enabling users to access and use it without any deployment on their machines or servers.
Stay tuned…
Alongside the open source development of SysON, Obeo is working on advanced commercial features to support cutting-edge deployments for large-scale and/or mission-critical projects.
Stay tuned…The project team works in an iterative mode to deliver a new version every 8 weeks.
The first release of SysON, version 2023.12, was launched in December 2023 by Obeo and CEA List.
The SysON roadmap takes into account user feedback and needs identified as part of an Open Innovation approach.
For the next months, our main goals include:
Achieving a first level of maturity for SysML V2 modeling with SysON, suitable for teaching, research, and industrial pilot project activities. sonic generations mods not working link
Expanding industrial collaborations, via an Early Adopter Program, to prepare for deployment and usage in operational contexts in 2026. Are you running into a specific or a
