Download Composer using the Eclipse Update Manager
TopBraid Composer is implemented as an Eclipse plug-in. Eclipse is a powerful open-source platform for all kinds of modeling and programming languages. The integration of Composer into this platform means that you can exploit the benefits of an integrated development environment. Eclipse also provides an update mechanism that allows users to conveniently update plug-ins such as TopBraid Composer when a new version becomes available.
The following instructions describe how to install TopBraid Composer into an existing Eclipse installation, using the Eclipse Update Manager.
Point your browser to http://www.eclipse.org/downloads and get the corresponding version for your operation system. Note that TopBraid Composer requires Eclipse 3.3 or above. Also note, if you have an existing installation of Eclipse together with other plugins, you may want to create a fresh Eclipse installation for testing Composer. It is OK to have multiple installations of the Eclipse platform on your computer.
We recommend downloading Eclipse 3.3 Classic or above.
When you start Eclipse for the first time, a dialog will ask you to specify a folder for your project files. This will be the physical location of your OWL and RDFS files later. You can specify an existing folder if you wish, but you could also create a subfolder of your eclipse home directory.
Depending on your existing Eclipse installation, you may need to add some basic plugins (e.g. GEF, EMF and UML2). These plugins are required by TopBraid Composer, but also from other components of your installation. The following external features are required from the Europa Update Site:
Enabling Features:
XML Schema Infoset Model (XSD) org.eclipse.xsd.edit

In the Proxy settings group, check Enable HTTP proxy connection and fill in your HTTP proxy host address and port.

Finally, restart Eclipse to activate the new plug-in.
