Modeling Language

A modeling language is a formal language used for specifying, visualizing, constructing, and documenting the artifacts of a system. Modeling languages are used in software engineering, systems design, enterprise architecture, and data modeling to capture structure and behavior in a way that can be shared, reasoned about, and turned into running systems. This index tracks modeling languages and notations relevant to the API and software design space.

Modeling Language is profiled on the APIs.io network. Tagged areas include Modeling Language, System Design, UML, SysML, and Architecture.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/modeling-language: open an issue to ask a question, or submit a pull request to add artifacts.
