System metadata for Links
When links are published on Pages, the following metadata is also published: a list of Pages that contain a given Component Presentation (for Component Linking), and a list of Component Presentations that are on a given page (for Profiling & Personalization).
The following is a Component example:
<component-link id="4592">
<page component-template-id="4588" id="4593" position="0" template-priority="200" url="/SG/kevin/simpleMETA.jsp"/>
</component-link>
And the following is a Page example:
<page-link id="4593" url="/SG/kevin/simpleMETA.jsp">
<component id="4592" position="0" template-id="4588" template-priority="200"/>
</page-link>
