FAQs

What is the Sodius Publisher Family?

The Sodius Publisher Family is a suite of automated tools that enable seamless model transformation between MBSE platforms such as IBM Rhapsody, Sparx Enterprise Architect, UNICOM System Architect, and Cameo Systems Modeler. These plugins convert SysML and UML models with complete diagram fidelity, hierarchy, and traceability, eliminating the need for manual rework.

How is the Publisher different from using XMI export/import?

Unlike standard XMI-based exchanges, the Publisher preserves diagram layouts, model profiles, and tool-specific semantics. XMI exports often lose visual and semantic information — which represents up to 90% of a model’s engineering value. The Publisher solves this by mapping how each tool actually implements SysML/UML internally, ensuring the result looks natively built in the target tool. You can read more in our blog article about XMI export/imports.

What kind of models can I convert?

You can convert a wide range of SysML and UML diagrams, including:

Block Definition, Internal Block, Package, and Parametric Diagrams
Activity, Sequence, State Machine, and Use Case Diagrams
Custom and content diagrams (including non-UML elements)

The Publisher supports large-scale transformations — up to hundreds of thousands of model elements and thousands of diagrams.

Does the Publisher require an internet connection?

No. The Publisher runs completely offline, making it suitable for classified and air-gapped environments in defense and aerospace programs. You can install, configure, and execute conversions without connecting to external networks.

Is there a free trial available?

Yes. You can request a free evaluation license to explore the full functionality of the Publisher tools here. The trial provides complete export/import capability with only a small watermark disclosure on output diagrams.

How is Sodius validated for defense programs?

The Publisher for Rhapsody has been approved by NAVAIR with a Commercial Item Description (CID) and recognized by the Defense Contract Management Agency (DCMA) as a reusable, commercial solution. Sodius is also Trade Agreements Act (TAA) compliant and deploys in both classified and non-classified environments.
