A piece of code that performs a single unit of work during the migration process. The following is an example of an XML-based rule that finds and reports on instances of weblogic-ejb-jar XML files and provides a link to an article on the Red Hat Customer Portal that describes how to migrate the file.

<rule id="weblogic-xml-descriptor-04000">
    <when>
        <xmlfile matches="/weblogic-ejb-jar" />
    </when>
    <perform>
        <classification title="WebLogic EJB XML" severity="mandatory" effort="3">
            <link href="https://access.redhat.com/articles/1326823" title="Map weblogic-ejb-jar.xml Elements to the jboss-ejb3.xml Descriptor" />
            <tag>ejb</tag>
        </classification>
    </perform>
</rule>

A ruleset is a group of one or more RuleProviders that targets a specific area of migration, for example, Spring Java EE 6 or WebLogic JBoss EAP. A ruleset is packaged as a JAR and contains additional information needed for the migration, such as operations, conditions, report templates, static files, metadata, and relationships to other rulesets. The following Windup projects are rulesets.
