the Department of Computer Science at RWTH Aachen (a German university) conducts a survey about modeling and model driven development.

So, if you have worked in a model driven project or a project that makes use of modeling in some way please consider to participate. The more people answer, the more representative the results will be.

we have released the new version 2.2.0 of Oclarity, our OCL authoring environment.

This release contains a couple of bug fixes in the parser and the OCL standard library. These bugs where found by evaluating the OCL expressions from Joanna Chimiak-Opokas and Birgit Demuths OCL course.
Thanks a lot to Joanna for making these expressions available to EmPowerTec for testing purposes, they where really helpful.

we have released the new version 1.0.2 of our UML Metamodel Viewer.

This version uses the official OMG UML 2.3 cmof-files. The previous versions used an earlier, not yet finalized release of these files.

The UML Metamodel Viewer displays an Explorer-like view of the UML2 metamodel. It can also draw class diagrams in a semi automatic way. These diagrams give you a better understanding of a classes dependencies and interactions.

UML Metamodel Viewer with a diagram

You can:

• Create and customize diagrams by dragging and dropping classes from the Model Explorer on a diagram
• Organize diagrams in projects
• Scale diagrams
• Print diagrams

The UML Metamodel Viewer requires some third party software, that has to be installed on your computer as a prerequisite:

• The graphviz package
• A Java JDK
• The UmlGraph jar-file

The location of these files must be configured in the UML Metamodel Viewers option dialog.

You can read the manual to learn more.

It is free, so just try it out!

we have released the new version 2.1.0 of Oclarity, our OCL authoring environment.

Oclarity main window

This release brings more robust XMI imports for Enterprise Architect and MagicDraw XMI files. The XMI import was also updated to support the latest version of these tools (Enterprise Architect 8.0 and MagicDraw 16.9).

Also Oclarity now supports a configurable mapping of model types to OCL builtin types. For example, if a type in the model is called ‘int’, chances are, that it should be treated like the OCL builtin type ‘Integer’. For earlier versions of Oclarity ‘int’ and ‘Integer’ were always distinct types. Starting from version 2.1, ‘int’ and ‘Integer’ are treated the same. Oclarity comes with a list of default type mappings, which can easily be extended.

See this page for all changes. You can also read the manual to learn more.

Starting with this release we will no longer use the Postfix “XMI” for the XMI based version of Oclarity. That prefix was used when we introduced the XMI based version of Oclarity as a distinction to the original version of Oclarity which was designed as AddIn for Rational Rose ™. Since we do longer support Oclarity for Rational Rose and Rose is outphased by IBM Rational since years, this distinction seems unnecessary.

Oclarity is free, so just try it if you are interested in the Object Constraint Language.

if you you need to use the UML2 Metamodel in some way for your work you will have noticed, that it is not easy to develop an understanding of the Metamodel, even less to learn quickly about the classes, their attributes and their relations to other classes. Basically there are only the official specifications from the OMG which are a bit dry to read.

Enter our new, free UML2  Metamodel Viewer!

The UML2 Metamodel Viewer is a standalone Windows application that can be used to browse the package structure of the UML2 Metamodel and explore the contained classes. In addition, it is possible to draw diagrams from these classes in a semi automatic way.

Here is a screenshot of the main window:

To create a diagram simply add a new diagram to your project and drag one or more classes from the Model Explorer to the diagram. For example, here is a diagram with the class Kernel::Classes::Class:

One of the neat features is that the related classes (superclasses and classes that are used in relations) are automatically added to the diagram. This is an easy way to see the “context” of a given class.

The installer comes with a manual that should get you started using the UML2 Metamodel Viewer.

There is a catch: currently UML2 Metamodel Viewer relies on some third party software (namely the Graphviz package and the UmlGraph package – the latter additionally requires a Java Development Kit) that must be installed and configured so that diagrams can be created.

This is a 1.0 release,  so you will surely find bugs using this software.  Please report bugs and feature suggestions to support@empowertec.de. We definitely appreciate your feedback! We plan to actively support this software, which means of course fixing bugs but also implementing new features depending on demand and effort.

The software is based on the cmof-files that define the UML2 Metamodel.

Best regards,
Andreas

we just released version Oclarity/XMI version 1.6.1.

This is a bug fix release. When releasing version 1.6.0 we did not realize that Sparx Systems had modified Enterprise Architects XMI export in such a way that it generated additional artifacts. In particular, after importing the XMI file, Oclarity/XMIs internal model contained additional associations (for examples superclasses where added as associations) and it contained some packages which are only used for Enterprise Architects internal use (’EA_*Types*Package’ packages). We did not notice the additional associations because they did not break our unit test – the additional elements did not create any problems when checking OCL expressions.

Finally, you might have noticed that attributes in the Model Explorer started with a number, e.g. 1. This was the internal representation of the members visibility. We have now corrected and extended this behavior so that the visibility is correctly displayed in the Model Explorer for all members.

Here is a list of all changes.

Oclarity/XMI is a free tool for checking OCL expressions against XMI files. If you have any problems, questions or suggestions about Oclarity/XMI please do not hesitate to contact us.

we just released version Oclarity/XMI version 1.6.0.

This is mostly a bug fix release.

We updated the XMI reader so that it processes the XMI files written by the latest version of Enterprise Architect correctly and we improved the OCL parser and semantic checker.
