I think it would be particularly good if infoboxes of the same "class" were linked. For example, if I have an infobox, e.g. Infobox_episode or infobox_books, it would be nice if there was a particular group that simply collected all this information and presented it as a navigation, as shown below:
<!-- Infobox on page stargate--> {{infobox books|name=Stargate|published=1999|author=MacGuyver}}
<!-- Infobox on page MacGuyver--> {{infobox books|name=MacGuyver|published=1995|author=Mr fixit}}
A sample infobox could be generated using:
<infobox> <data source="name"/> <data source="author"/> <data source="published"/> <group type="classlinks" header="Available books"/> </infobox>
There could be options to customize classlinks. This can currently be done by using javascript or lua or regular templates. But it requires dpl or hardcoding of all data.
Edit:Made some changes.
