Model Transform Tools (MTT)

"A picture paints a thousand words."
— Fred R. Barnard

Exposing APIs for your business services offers significant benefits, but designing them by hand is slow, repetitive, and error-prone. Model Transform Tools (MTT) solves these problems by generating deterministic API specifications, schema definitions, and static documentation directly from graphical domain models.

Why Use MTT?

  • Define Once, Generate Many

    Generate OpenAPI, GraphQL, Protobuf, Markdown, and custom data standards from a single output-agnostic model.

  • Improve Efficiency

    Reduce development costs significantly. For example: The Library sample project automatically generates over 7,500 lines of OpenAPI and 450+ lines of GraphQL.

  • Incorporate Best Practice

    Implement local standards and enterprise rules once in the transform engine, resulting in architectural rigor and consistency across all generated artifacts.

  • Democratise Development

    Standard UML diagrams allow business analysts, enterprise architects, and domain experts to participate in model reviews before writing server code.

  • Technology Independence

    Generate implementation-agnostic specifications rather than locked-in framework code, giving engineering teams total freedom to choose target languages.
