<div class="jive-rendered-content"><p>JBoss Central, based on <a class="jive-link-external-small" href="http://wiki.eclipse.org/Mylyn/Discovery" rel="nofollow">Mylyn Discovery</a>, is in part a UI for installing new features into Eclipse or JBDS. It provider a richer, yet simpler UI than what Eclipse's p2 Install Manager provides out of the box. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-size: 12pt;"><strong>The Software/Update tab in Central is backed by three levels of metadata:</strong></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><ul><li style="text-align: start;">directory.xml file listing 1 or more discovery plugins (eg., 1 for the Core features, 1 for the Integration Stack (formerly SOA Tooling) features)</li><br/><li style="text-align: start;">discovery plugin(s), which define groups of features ("Connectors") to be installed.

Sites can be 3rd party vendors' sites, or can be mirrored on download.jboss.org / devstudio.jboss.com for better guarantee of performance / version. Each connector can only define a SINGLE URL for that group of features, however.
