Hello,

Og tags are already inclued, you can add custom ones using Joomla!'s API (addMetadata / addCustomMeta) in your item.php file overrides ( getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates )

Some example code can be found here github.com/kricore/Advanced-templating-with-K2/blob/master/_inc/cheatsheet.php#L176-L191
