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.
SysON aims at facilitating systems engineers to seamlessly work with both SysML v2 and Capella. Exchange of architecture models with Capella will be natively supported in SysON.
The allure of the OVE lay in their exclusive focus on outdated RPH versions. While other modders moved on to newer, more popular engines, the OVE members reveled in the challenge of breathing new life into abandoned code. They pushed the boundaries of what was thought possible, creating remarkable mods that not only worked but also introduced innovative gameplay mechanics.
The developers of RAGE Plugin Hook have made their stance on redistribution very clear: "Do not upload RAGE Plugin Hook in whole, or in part, to any other website, and do not include it with your plugins". This strict policy is the primary reason why old versions are not readily available on a central, official archive. The creators view the software as their copyrighted work, and redistributing it without permission is a violation of their terms.
The radio crackled again.
Common exclusive/old versions sought:
🔍 – Open RagePluginHook.log after a crash. It shows required RPH version.
// Old exclusive: Checking for GameVersion enum values that no longer exist // e.g., v1_0_877_1_Steam if (Game.Version == GameVersion.v1_0_877_1_Steam)

He double-clicked the RagePluginHook.exe — the old one, the folder marked . The one everyone said to delete.
Ask in #legacy-plugins or #rph-help – trusted users often share old builds.
| Version Number | Game Patch Support | Era (Approx.) | Why It Was Sought After | | :--- | :--- | :--- | :--- | | | v1.0.335.2 | Mid 2015 | The "Wild West" era. These initial builds dealt with Rockstar's "efforts to prevent modding" and fixed critical crash dialogs. Version 0.22 was a massive turning point for LSPDFR support. | | 0.47 | v1.0.877 | Late 2016 | A volatile but important patch. This version removed support for game patch v791 (forcing users to update) and added support for v877. Many mods broke, but those who needed v877 support were forced to find this specific hook. | | 0.52 | v1.0.1032 | Late 2017 | This version added support for Game Patch v1032 but forcibly removed support for Game Patch v1011 . If you had a mod saved to a specific folder structure, you were locked into this version. | | 1.78+ | 1.0.1868+ | 2020 - 2021 | The era of "Emergency Lighting System" (ELS) fixes. Users specifically downgraded to 1.0.1868.0 to fix broken police lights, requiring RPH 1.78 to match. | The allure of the OVE lay in their
Official distribution of older RPH versions is strictly controlled to prevent unauthorized redistribution.
Finding legacy versions of RPH can be incredibly difficult because the official Rage Plugin Hook website typically only highlights the latest public release. Furthermore, downloading files from random file-sharing mirrors puts your PC at extreme risk of malware.
The absolute best source for an exclusive old version is your own storage. Once you achieve a perfectly stable, heavily modded GTA V environment, manually copy your entire Grand Theft Auto V root folder—or at least the RagePluginHook.exe , RagePluginHook.log , and the SDK folder—to an external drive.

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:
In 2025, we will intensify our collaborations with industrial partners to elevate SysON to the forefront of SysML V2 modeling tool excellence
and prepare it for professional, operational, and large-scale deployment.
