Create your first (meta)model

Create your first metamodel

In this section, you’ll learn how to create a metamodel and its corresponding model in Jjodel. Metamodels define the structure of your modeling language, while models are the instances of those structures. Follow these steps to design your first meta/model and start your modeling journey.

 

The whole procedure is also illustrated in the following video:

 

Create your first Metamodel

This video provides a clear, step-by-step walkthrough for creating a basic Person-Organization metamodel in Jjodel. It demonstrates how to define key classes (Person and Organization), add attributes (name, age, industry), and establish relationships like belongsTo. Designed for beginners, the video emphasizes simplicity and guides viewers through the process of building and visualizing their first metamodel, making it an excellent starting point for learning metamodeling.
