OpenSysML Forum
A community forum for the OpenMBEE and OpenSysML ecosystems — discussing, sharing, and improving practices and models for Model-Based Systems Engineering (MBSE) and Digital Engineering.
The Open SysML Forum exists to bring together practitioners, tool builders, researchers, and newcomers working with SysML, OpenMBEE, and related MBSE tooling. Whether you're debugging a model, comparing digital thread strategies, or just getting started with systems engineering, this is the place to ask, share, and learn.
This wiki is the front door to the community — use it to find your way around, learn how things work here, and discover resources maintained by the group.

The Open SysML Forum supports two closely related communities:
| Community | Focus |
|---|---|
| OpenMBEE | Open-source Model-Based Engineering Environment — tooling for managing, integrating, and publishing systems models |
| OpenSysML | Practices, extensions, and open discussion around the SysML modeling language (v1 and v2) |
Together, this forum is a home for:
- Sharing modeling patterns and reusable model libraries
- Discussing tool workflows (Cameo, MagicDraw, Papyrus, MMS, etc.)
- Comparing approaches to Digital Engineering and the digital thread
- Troubleshooting and technical support
- Highlighting case studies and lessons learned
- Coordinating on standards, extensions, and best practices
New here? Start with these steps:
- Read the Community Guidelines below.
- Introduce yourself in the introductions thread — tell us what you work on and what brought you here.
- Browse the Discussion Categories to find topics relevant to your work.
- Search before posting — many common questions are already answered.
- Ask away! No question is too basic, and detailed answers help future readers too.
| Category | Description |
|---|---|
| MBSE Best Practices | Modeling patterns, architecture frameworks, style guides |
| SysML v1 / v2 | Language questions, migration notes, spec discussion |
| OpenMBEE Tooling | MMS, View Editor, model management, integrations |
| Digital Engineering | Digital thread, digital twin, model-based data exchange |
| Tools & Interop | Cameo, MagicDraw, Papyrus, and cross-tool workflows |
| Case Studies | Real-world project write-ups and lessons learned |
| Help & Troubleshooting | Setup issues, error messages, "how do I…" questions |
| Announcements | Community news, releases, and events |
- Be respectful. Assume good intent and disagree constructively.
- Stay on topic. Keep threads focused on MBSE, SysML, and Digital Engineering.
- Search first. Check existing threads and this wiki before opening a new one.
- Share context. Include tool versions, model snippets, or diagrams when asking for help — it gets you better answers, faster.
- Give credit. If you're sharing someone else's model, pattern, or write-up, link back to the source.
- No spam or self-promotion outside of designated announcement spaces.
- OpenMBEE — official project site
- OMG SysML Specification — language specification
- SysML v2 Submission Team — next-gen SysML development
- INCOSE — systems engineering body of knowledge
- Community-maintained model libraries and example projects (linked as they're contributed)

This wiki is community-maintained. To contribute:
- Fork or clone the wiki repository.
- Add or edit a page using standard Markdown.
- Keep pages focused — one topic per page, linked back to this Home page.
- Open a pull request (or push directly, if you have write access) with a short description of your change.
- Tag a maintainer if you're proposing a new top-level section.
Is this forum affiliated with the OMG or INCOSE? No — it's an independent community space for practitioners in the OpenMBEE and OpenSysML ecosystems.
Do I need to be an expert to participate? Not at all. Beginner questions are welcome and encouraged.
Where do I report a bug in OpenMBEE itself? Use the appropriate OpenMBEE GitHub repository's issue tracker rather than this forum.
