At this point there were two exciting innovations. The first is a way to display metadata differently with one condition. A typical application scenario is the display of licenses. The title of the license should always be displayed (e.g. "CC BY-SA 4.0", "Public domain", ...). However, if there is another metadata with a URL, the title should be displayed, but clickable, and the link opens. The display of the metadata is therefore always "pretty" and sometimes - if available - with a link deposited.
