Read the Collaborative modeling section to learn more about how to collaborate using SysON.

How will models developed in your tool, be shared with other vendor SysML v2 tools? Are there any limitations we should be aware of?

We’re fully compatible with the SysML v2 standard. Models can be shared using the SysML v2 textual notation and the SysML v2 API.

How will models in SysML v2 and models in SysML v1 co-exist?

SysON is a pure SysML v2 player. Currently, SysML v1 models can’t coexist within SysON, but coexistence might be possible within your SysML v1 tool.

How do I integrate SysON with other tools or systems?

SysON is a specialized tool for SysML v2, focusing on the latest standards and methodologies, offering robust compatibility with SysML v2 through features such as textual notation support for model import/export, full compliance with the SysML v2 API for seamless integration with other tools, and ongoing integration efforts with Capella for enhanced model interoperability.

How’s your SysML v2 tool integrated with other products you offer?

SysON is designed to be a specialized tool for SysML v2, focusing on the latest standards and methodologies. Currently, as an open source product, SysON is primarily focused on ensuring robust compatibility within the SysML v2 ecosystem. This includes integration capabilities such as:

  • Textual Notation Support: SysON supports importing and exporting models using the SysML v2 textual notation. This facilitates sharing and integration with other SysML v2 compatible tools.

  • SysML v2 API: SysON is fully compatible with the SysML v2 API, allowing seamless interaction with other tools and systems that adhere to this standard.

  • Integration with Capella: We’re working on establishing integration pathways with Capella, a comprehensive model-based engineering solution.

This will enable users to leverage SysON’s SysML v2 capabilities alongside Capella’s powerful system architecture modeling tools, ensuring model interoperability.

Will you have a method to convert SysML v1 models to SysML v2 models?

While addressing SysML v1 model support is currently beyond the scope of SysON, we acknowledge its potential as a valuable extension for the tool. We’re open to collaborations with individuals or organizations interested in contributing to such extensions. We invite those who share our vision and are committed to enhancing SysON’s capabilities to contact us to discuss potential partnerships.
