<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">One thing that I have found it necessary to build for every significant application in which I have used the MDA is a bean catalogue. By this I mean a <tt>beans.xml</tt> file that defines abstract beans for each bean class I use from the MDA, named after that class but including lazy instantiation and defining common items such as the initialize and destroy method names. This simplifies actual bean declarations, which are made from the parent bean rather than specifying a class.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">See for example: <a href="https://github.com/ukf/ukf-meta/blob/master/mdx/common-beans.xml" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">https://github.com/ukf/ukf-meta/blob/master/mdx/common-beans.xml</a></p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I think this is enough of a common pattern to provide as part of the distribution, invoked through an import of <tt>classpath:net/shibboleth/metadata/beans.xml</tt> or the like.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">It makes sense to include a fixed prefix (suggestion: <tt>mda.</tt>) in each name, so that we end up with, for example, <tt>mda.DOMResourceSourceStage</tt>.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">It doesn't seem to be necessary to include all of the package hierarchy in these abstract bean names, although it might make sense to include some grouping for function. This would be the same kind of choice as we have made in IdP bean configuration files (where the prefix is <tt>shibboleth.</tt>.</p>
