Microdata API has been removed

Published: | Categories: DOM

Description

The Microdata DOM API was implemented with Firefox 16 but later removed from the HTML5 spec, and no other browsers are implementing it so far. The support for the obsolete API has been removed with Firefox 49 in hope of avoiding further site compatibility issues mainly due to the itemId property. For upward compatibility, Web developers are still encouraged to use the dataset property instead of any arbitrary properties.

Note that Microdata itself is still a part of the HTML Living Standard (but not in W3C HTML) and widely used for structured data markup especially with Schema.org vocabularies. Firefox has just removed the DOM API support.
