<div class="jive-rendered-content"><p><strong>Central consists of three levels of metadata:</strong></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></ul><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><ul><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. But that single URL can be a composite site, which in turn points to more than 1 site.</li></ul><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span class="author-a-rhfgxz76zfz67zz90zuz74zbz78zz88zez83z b"><strong>There are two simple rules to follow when writing your d</strong></span><span class="author-a-4qz82zz70zz69zz67zg9z69zz66z8q5z75zcz122z b"><strong>iscovery plugin.xml:</strong></span></p><p><span class="author-a-4qz82zz70zz69zz67zg9z69zz66z8q5z75zcz122z b"><strong><br/></strong></span></p><p style="min-height: 8pt;
