Eclipse is probably best known as a Java IDE, but it is more: it is an IDE framework, a tools framework, an open source project, a community, an eco-system, and a foundation.https://www.eclipse.org/eclipse.org-common/themes/solstice/public/images/logo/eclipse-200x200.png
The standard ATL install provides ATL Engine and IDE. With the standard version, you should only deal with EMF compliant models. To handle and transform other models, you should use specific driver. Additional drivers (MDR and UML2) are available the driver category. We recommend that you use the Eclipse Update Manager to install ATL. Use only the "Search for new features.." option when installing with Eclipse 3.3.
