mAUmL

mAUmL is a fictional modeling language used in educational materials and online prompts to illustrate a compact, human-readable approach to modeling inspired by the Unified Modeling Language (UML). It is not an officially standardized language and has no formal specification or widely used tooling. The name is commonly described as standing for 'minimal Abstract UML Language' and is employed to teach concepts rather than to define a production-ready syntax.

Design and features: mAUmL aims for simplicity and readability while retaining core UML concepts such as classes, attributes, operations, and relationships. It supports class definitions, basic data types, and simple constraints. Relationships include associations, generalizations, aggregations, and compositions, expressed in a compact textual form. Constraints can be attached to classes or relationships using a lightweight syntax. The language is intended to be easily parsed by hand and by simple scripts, and can be converted to standard UML diagrams or XMI with a defined translation mapping.

Example syntax: class Person { name: String; age: Integer; } class Employee extends Person { employeeId: String; } Person -- livesAt --> Address;

Usage and tooling: Because mAUmL is not an official standard, support is limited to tutorials and demo code. It can be used to sketch models rapidly or to teach UML concepts, and can be mapped to UML for diagram generation.

Origin and status: The term appears in online discussions and classroom materials since the early 2020s; it is not widely adopted and should not be confused with UML-based languages or formal DSLs with official definitions.
