muMLE

Tiny (meta-)modeling framework.

Features:

  • mostly textual concrete syntax
  • meta-modeling & constraint writing
  • conformance checking
  • model transformation primitives (match and rewrite)
  • rule-based model transformation
  • examples included:
    • Class Diagrams (self-conforming)
    • Causal Block Diagrams language
    • Petri Net language

Dependencies

  • Python 3.?
  • Python libraries:
    • Lark (for textual parsing)
    • Jinja2 (not a hard requirement, only for model-to-text transformation)

Development

The following branches exist:

  • mde2425 - the branch containing a snapshot of the repo used for the MDE assignments 24-25. No breaking changes will be pushed here. After the re-exams (Sep 2025), this branch will be frozen.
  • master - currently equivalent to mde2425 (this is the branch that was cloned by the students). This branch will be deleted after Sep 2025, because the name is too vague.
  • development - in this branch, new development will occur, primarily cleaning up the code to prepare for next year's MDE classes.

Tutorial

A good place to learn how to use muMLE is the tutorial directory. Each file is an executable Python script that explains muMLE step-by-step (read the comments).
