Description

Refers to a parent document in a hierarchy of documents.

Example

A page (https://prlbr.de/galerie/14/am-pranger/) in a photo gallery showcases a photo. The page defines multiple link relations which refer to the

• next page which contains the next photo from the gallery
• previous page from the gallery
• parent page using up, which shows previews of many photos as thumbnails including the current one and includes links to their corresponding pages.

<link rel='next' href='/galerie/14/mustergatte/'>
<link rel='prev' href='/galerie/14/linie-1/'>
<link rel='up' href='/galerie/seite-6'>

next and prev relate to documents on the same hierarchy level while up moves one level up.
