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.
Standards
The link relation up is recognized in standards:
- IANA link relations registry (https://www.iana.org/assignments/link-relations/link-relations.xhtml)
- XHTML vocabulary (https://www.w3.org/1999/xhtml/vocab#up)
- and hence XHTML+RDFa Initial Context (https://www.w3.org/2011/rdfa-context/xhtml-rdfa-1.1)
