Open Source UML Tools

NClass is a free tool to easily create UML class diagrams with full C# and Java language support.

The Whole Platform is a technology for engineering the production of software. We provide an Eclipse based Language Workbench for developing, manipulating and transforming languages using a model driven approach.

ODABA is an terminology-oriented database management system (TODBMS) on a high conceptual level. It provides a number of enhanced features based on natural language analysis. Terminology orientation allows designing user oriented data models. Enhanced event model and Active Data Link technology support rapid development of GUI applications. Several development, documentation, test and analyzing tools are provided in order to support developers and administrators. .NET interface and a powerful object-orjented script language (OSI) improve development efficiency.

A component based programming framework. This project is aimed to support various target frameworks. A wxWidgets based GUI application is the major sample which also provides rapid database GUI design with UML import and export (db reverse engineering).

JAG - the Java Application Generator - is a 100% Java application that generates working projects containing complete, best-of-breed J2EE applications.

Coral is a tool and a development platform to create and transform models and modeling languages. It can be used to edit UML models, to develop editors for other modeling languages and to implement MDA and QVT-like model transformations.

The Introspector enables the programming tools that deal with source code such as the compiler to communicate in a standard and neutral manner reducing the accidental cost of programming. http://github.com/h4ck3rm1k3/

Tefkat is the transformation engine for the Eclipse Modeling Framework (EMF). It implements a state-of-the-art declarative model-to-model transformation language, including a source-level debugger and support for UML2, MOF2, and XML Schema-based models.

The Amplify MDA project is aimed at delivering a 'model-to-text' generator tool with real-world applicability in less than 1000 lines of Java/Groovy code.

A JML generator. Generates JML specifications based on other specification formalisms.

The BDT (Build Development Tools) Project is working towards providing a fully functional Build Integrated Development Environment (IDE) for the Eclipse platform.

CHSM is a language system for specifying concurrent, hierarchical, finite state machines (an implementation of "statecharts") to model and control reactive systems.

This projects aims to be an UML modeling tool and a set of reusable components for other projects.

A set of tools and utilities that allow development teams to practice code generation techniques in a scalable and extensible manner. This is based on the style of code generation found in Ruby on Rails.

DTDS is a system of definition of data types for unification of information exchange with use of different Samond Classes Library functions and for generation of source texts based on the completed data type definition

The goal is to generate UML classes from an existing database. Connect to a database, read its schema and produce UML 2 classes with associations (conforming to Eclipse EMF). Prerequisite: - Eclipse 3.4 - MDT - EMF 2.4 / UML 2.0

Deduced is used to edit and generate model classes. It also provides tools to implement code deduction patterns. It also simplifies data exchange and persistance.

drawcode é um plugin do eclipse para edição de diagramas de classe e NS(Nassi & Shneiderman), com a possibilidade de gerar código a partir da associação destes 2 tipos de diagramas.

Dresden OCLallows to query arbitrary EMF-based models. It provides an advanced OCL2 Editor, a Parser, an Interpreter, and a Codegenerator for Java and SQL. WE MOVED TO GITHUB. PLEASE VISIT https://github.com/dresden-ocl/dresdenocl

EGG is a development tool for fast and easy realization of XML to plain-text tranformations. It's similar to XSLT, Velocity or JSP but emphasises source-code generation in a model-driven, generative development-process. For Windows or Unix with Java.

An Eclipse plugin for generating code out of an Entity-Relationship-Diagram (ERD). Currently SQL-DDL and POJO classes with EJB3.0 Annotations are supported. The diagrams conform to the diagram description by H. Buff (german book, ISBN 3-03-440201-5)

EasyStruts provide advanced support for developing Struts web applications with Eclipse . keywords: MVC, Struts, Eclipse, Java

The EmfUtils provides UI enhancements for EMF (Eclipse Modeling Framework). It helps to locate the non-generated, self-written code in sources generated with EMF. You may install it from the Eclipse Update Site URL http://emfutils.sourceforge.net/updates

MERMAID is an object-oriented domain modeling tool to create enterprise models using an UML class diagram, an object-event table and finite state machines. The CASE tool checks view consistency, has XMI support and code generation abilities.
