The Howdy Glossary

Epsilon is a domain-specific language designed to enhance efficiency and adaptability in model-driven engineering (MDE) processes. Created by Dimitrios Kolovos and his team at the University of York's Department of Computer Science, Epsilon serves as an executable modeling language that simplifies high-level specifications into various project elements using interpreters or generators integrated within the Eclipse Modeling Framework (EMF). This capability eliminates the need for manual coding at a lower level, streamlining intricate tasks throughout the software development lifecycle.

Epsilon stands out due to its distinctive features tailored to software development in model-driven engineering. It provides a suite of specific languages for transformations, validations, code generation, and model-to-model operations. By enabling the creation of high-level specifications that can seamlessly transition into implementation code through EMF-integrated interpreters or generators, Epsilon supports developers in capturing complex tasks without needing manual authoring of low-level code. This user-friendly approach enhances productivity and flexibility by allowing developers to harness domain-specific languages for intricate tasks.

Despite facing competition from other domain-specific languages like ATL, QVT, Xtend, and Acceleo—each with their unique focus such as model-to-model transformations or template-based code generation—Epsilon distinguishes itself through its comprehensive suite covering multiple MDE tasks under one platform. Its integration with EMF further enhances usability by facilitating seamless transitions from high-level specifications to implementation code or project artifacts. This versatility positions Epsilon as a robust tool capable of addressing numerous development tasks within the software lifecycle while maintaining ease of use and effectiveness in model-driven engineering projects.
