From Aptana Development

The views extension point allows the library to contribute an HTML view to the IDE. Examples of this can be found in the EXT or jQuery projects where they provide documentation or external functionality.

Note the special URL starting with bundleresource:// which allows us to specify a resource local to this plugin.

Examples

<extension
       point="org.eclipse.ui.views">
       <view
           category="com.aptana.ide.documentation"
           class="com.aptana.ide.core.ui.views.browser.DefaultBrowserView"
           icon="icons/library.png"
           id="com.aptana.ide.documentation.libraryname.sampleview"
           name="LibraryName Sample View">
           <description>bundleresource://org.library.name.0.0/views/sampleview/sampleview.html</description>
