The Generic Eclipse Modeling System (GEMS) is a MDD tool for Eclipse that allows for the rapid development of visual modeling tools for Eclipse based on EMF/GEF. Developers specify the rules for a domain language using a metamodel and the tool generates a diagram editor plugin that enforces the rules from the metamodel. Interpreters can then be written to traverse the model and generate code, perform analyses, or execute the model. The tool supports complex model analysis using Prolog; Java, OCL, and Prolog constraints, remote model updating via CORBA, applying CSS styles to models, model-to-model linking, exportable templates, and more.
QiQu is a framework to support the MDA and MDSD approach. It transforms a UML model into source code. It lets you build your own domain-specific generators that transform your models into the code of your choice, respecting your architectural design. You are not limited to any predefined transformation engines or cartridges, nor to any predefined transformation rules. Since QiQu heavily relies on XML, you can not only convert from XMI (representing UML) to source code, but from any XML format into anything else.
Snippetory is a general Java template engine based on passive templates. In passive templates, template code and logic are clearly separated from each other. The templates contains very simple mark up. By removing logic, templates are directly accessible, fully parametrized, and free of context, and can easily be reused. Navigation, code competition, and structuring of the code with methods and classes are supported.
