WHAT IS PUBLISHER?

Purpose-Built for MBSE Model Conversion

Publisher is SodiusWillert's dedicated model conversion solution for systems engineering teams. It converts system models between leading MBSE tools accurately, completely, and without the data loss caused by generic export/import workflows.

Unlike XMI-based conversions or manual migration scripts, Publisher understands the internal semantics of each supported tool. The tool maps stereotypes, tagged values, relationship structures, and diagram layouts with precision, delivering a model in the target tool that is ready to use immediately.

Publisher is designed for aerospace and defense programs where model integrity is a program-critical requirement, and where the cost of a failed migration is measured in schedule delays, compliance risk, and months of lost engineering work.

WHO IT'S FOR

Built for the scenarios that cost teams the most

Whether you are migrating a legacy program, delivering to a customer's tool standard, or enabling cross-team collaboration, Publisher has you covered.

Program tool migrations

Your program has been acquired, restructured, or is transitioning from IBM Rhapsody to Cameo/MagicDraw. Migrate your entire models in hours.

Customer delivery requirements

Your customer or prime contractor requires delivery in Cameo/MagicDraw format, but your team works in IBM Rhapsody. Publisher lets you keep your tools and meet the delivery standard, faithfully.

Partner collaboration

Different partners (e;g. contractors, subcontractors, etc) may be on the same program and use different modeling tools. Publisher bridges the gap so teams can exchange models freely without losing structure, diagrams, and traceability.

Iterative bidirectional worklows

Some teams need to work iteratively across different modeling tools (e.g. publishing Rhapsody models to Cameo). UID-based roundtrip support makes this repeatable and reliable.

Digital engineering transformation

Organizations adopting digital engineering frameworks can use Publisher to consolidate model repositories, preserve knowledge, and reduce legacy tool debt.

CONVERSION SCENARIOS

BENEFITS

Why engineering teams choose Publisher

Complete Model Fidelity

Every element, relationship, stereotype, tagged value, and diagram is faithfully converted. Publisher maps the semantics of the source tool to the target. There are no silent substitutions, no missing relationships, no lost engineering decisions.

No Manual Rework

The automated conversion workflow eliminates the need for engineers to recreate or re-validate models post-migration. Teams that previously spent weeks on cleanup after a failed migration find that Publisher delivers a model that is ready to use immediately.

Hours, Not Months

What takes engineering teams months, sometimes years, to do manually, Publisher completes in hours. This dramatically reduces program risk, keeps the digital thread intact across tool transitions, and frees your MBSE team to focus on engineering rather than migration logistics.

Enterprise Reliability, Proven in Production

Publisher has been used on complex, mission-critical engineering programs in aerospace, defense, and automotive. It is validated by leading systems integrators and trusted by organizations where model accuracy is critical program requirement.

FAQs

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.

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 Publisher 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.

How long does a typical conversion take?

Conversion time depends on model size and complexity, but Publisher consistently completes in hours what manual migration would take weeks or months. Most production-scale models used in aerospace and defense programs are converted within a working day. A detailed time estimate can be provided after an initial model assessment.

Do we need to validate the converted model manually after conversion?

Publisher generates a detailed conversion report that documents transferred element and flags any items that require attention. Program teams can use the report to sign off on the conversion with confidence.

Is Publisher a one-time tool or can it support iterative conversions?

Publisher supports both one-time migrations and iterative conversion scenarios, such as programs where the source model continues to evolve during a transition period. Contact us to discuss the specific requirements of your program.

What versions of Cameo are supported as the target?

Publisher currently supports Cameo Systems Modeler (MagicDraw) versions 19.0, 2021x, 2022x, and 2024x. If your program requires a specific version not listed here, contact us to discuss compatibility.

How do we get started?

The fastest path to getting started is to request a trial conversion. This lets you validate Publisher's output against your specific model before committing to a full migration. Contact us here or visit this page to request a trial.
