Template:Infobox on Central is not a very good example at all, in no small part because it's been so vastly removed from the default infoboxes as to be actually broken.

starter is the Starter Pages Wiki, where the pages that every new wiki gets are stored. Why don't you check out c:starter:template:infobox? Your wiki is likely to have that exact same code, which can be seen at http://starter.wikia.com/wiki/Template:Infobox?action=edit

That's the new infobox code, which is designed to be changed in Infobox Builder. The very same used to be written in typical template notation; you can see so at this old revision.
