ModelDesk was built from the conviction that data modeling deserves better tooling. Designed with deep knowledge of UML and RDF, and with the daily practice of data modelers and ontologists as the starting point.

Data modelers and ontologists working with UML, RDF, and related standards often rely on a patchwork of desktop tools, manual translation steps, and scattered documentation. ModelDesk brings the entire trajectory — from conceptual model to technical schema — together in one web environment.

Model, transform, and publish across modeling languages and schemas — with full traceability and version control. Entirely in the browser.

What ModelDesk does:

- Import existing models from XMI, RDF, or XSD
- Model with native metamodel support, including proper terminology and validation rules per standard
- Transform models between standards using configurable mapping rules
- Validate automatically against the rules of the chosen metamodel
- Publish to XMI, XSD, JSON Schema, RDF (Turtle, JSON-LD, RDF/XML), and more
- Align ontologies with AI-assisted suggestions and confidence scores
- Track provenance: every derived element preserves its source
- Collaborate within your organization with role-based access control

Built by domain specialists who have worked with these standards for years, and designed around the workflows that matter most: importing, modeling, transforming, validating, and publishing.

Your models, your formats, always exportable in open standards.
