UMLGraph

UMLGraph - UMLGraph allows the declarative specification and drawing of UML class and sequence diagrams. The current features are part of an ongoing effort aiming to provide support for all types UML diagrams. An IEEE Software article titled On the declarative specification of models explains the rationale behind this approach. The tehnology behind UMLGraph was used to draw many of the diagrams appearing in the award-winning books Code Quality: The Open Source Perspective (Addison Wesley, 2006) and Code Reading: The Open Source Perspective (Addison Wesley, 2003). In addition, the UMLGraphDoc doclet included in this distribution automatically adds UML diagrams to javadoc documentation.

MetaBoss

MetaBoss - As the business owner, you want the fruits of your IT investment to last longer and not be trapped in expensive and never-ending software redevelopment cycle. One of the underlying principles MetaBoss is built on is that the business domain and the business processes do not change as often and as radically as the information technologies do.

According to this principle, MetaBoss is facilitating the creation of software systems via technology independent modelling of business domains and processes.

Openmdx

Openmdx - openMDX is a open source MDA application framework. The framework helps you in writing service-oriented, platform-independent applications.

The application's interface is specified with a platform independent model (PIM) and the business logic is implemented as POJOs (plain old Java objects) which are platform-, distribution- and persistence-technology independent. The application can be deployed locally or distributed by using the RESTful, JDO compliant openMDX persistence manager. The resulting applications are lightweight (openmdx-base.jar is only 2.9M) and can be deployed on any J2SE or J2EE platform.

Here is how you get started in 2 easy steps
- Download and install the openMDX SDK. The SDK includes the demo applications Hello World and Workshop.
- Consult the openMDX documention where you will find step-by-step guides and additional information.

Taylor MDA

Taylor MDA - Taylor's model driven architecture on rails makes creating JEE applications as easy as the much talked about ruby-on-rails, but with all the power of JEE and UML. Business models are defined using simplified UML diagrams following well-defined conventions. These models are then used to generate the exact same ejb3/portlet code your would write by hand. Then use the code as is or modify it as you see fit and your changes will be preserved.

Taylor consists of a set of Eclipse plugins for simplified UML modeling and the generation of JEE code such as: EJB3 entity and session beans, JSR-168 Portlets, and JMS-based business processes. It leverages many other open-source tools instead of reinventing the wheel. Read more about the Architecture.

Why did I write Taylor? Check out my blog entry.

Taylor implements MDA. Model Driven Architecture (MDA) is the concept of first defining a Platform Independent Model (PIM) and then using the PIM to generate a Platform Specific Model (PSM). Taylor's simplified UML business models represent the PIM and its customizable templates generate the PSM.

Taylor also applies Convention-based Development. There are many ways to build the same application. But, if proven conventions are followed then code generation and development can be much more productive and can put you on the fast track to success. Hence MDA on rails. Taylor's simplified UML models embody these conventions.

Taylor distingishes itself from other tools by three key concepts:

Specialization/Simpification
Stereotypes/Annotations
Transparency

Green UML

Green UML - Green is a LIVE round-tripping editor, meaning that it supports both software engineering and reverse engineering. You can use green to create a UML class diagram from code, or to generate code by drawing a class diagram.

Green was developed with the pedagogical goal of focusing students on design. However green has proven to be a robust and flexible tool that can easily provide UML support in any environment.

All relationships are plug-in based extensions off of green. This means that at any time you can add your own relationships! This was added with the pedagogical goal of revealing relationships incrementally to students, and having green reflect only the relationships which our students have knowledge of!

The editor features a simple point-and-click interface. Right-clicking in the editor brings up a context-sensitive menu that includes features such as the refactoring and quick-fix functionality.

Green supports exporting files to both jpg and gif format, so that you can share you diagrams without any issues!

Green is an ongoing project at the University at Buffalo.

Violet

Violet - Violet is a UML editor with these benefits:

It is very easy to learn and use
It draws nice-looking class, sequence, state, object and use-case diagrams
It is completely free (includes source, distributed under the GNU General Public License)
It is cross-platform

Violet is intended for students, teachers, and authors who need to produce simple UML diagrams quickly. It is not intended as an industrial strength tool. There are several capable high-end UML editors available, such as

Rational Rose
Together
The free ArgoUML and its commercial cousin Poseidon

Those are fine programs for serious users of UML. However students and casual users may not like them because they are too slow, too expensive, or too hard to learn. Mike Godfrey coined the slogan: Roses are rational, violets are GNU.
Here are some of the features that industrial-strength UML programs have and that Violet does not have

Code generation. Violet does not generate any source code from UML diagrams.
Reverse engineering. Violet does not generate UML diagrams from source code
Semantic checking of models. You can use Violet to draw contradictory diagrams
XMI export or import. Violet does not generate files that can be imported into other UML tools, nor can it read model files from other tools

Fujaba

Fujaba - The Fujaba Tool Suite (shortly: Fujaba) is an open source CASE tool providing developers with support for model-based software engineering and re-engineering. The Fujaba project aimes at developing and extending the Fujaba Tool Suite and thus offering an extensible plattform for software engineering researchers. The Fujaba Development Group is permanently developing and extending Fujaba and numerous related tools.
Originally, Fujaba was aimed to support software forward and reverse engineering. That is why Fujaba is an acronym for "From UML to Java and back again".
Fujaba's main features are:

Powerful, easy to use, yet formal, visual, object-oriented software system specification language (UML class diagrams and specialised activity diagrams, so called Story Diagrams based on graph transformations)
Java code generation based on the formal specification of a systems' structure and behaviour which results in an executable system prototype.
An extensible CASE tool framework for researchers, who can develop their own Fujaba plug-ins.
Numerous Fujaba plug-ins providing support for example for
- Reverse engineering of source code by creating UML class diagrams, detecting design patterns, idioms, anti patterns, bad smells,...
- Model-to-model transformations specified by triple graph grammars, TGGs (also usable in case of model synchronisation)
- Modelling, validation and verification of embedded real-time systems
- Meta-Modelling with MOF (OMG meta object facility)
