: How to set itemprop="duration"? I’m trying to set a song’s duration with Microdata. What is the best way to describe a duration in Microdata? Is it by using itemprop="duration" in span?

@Ann8826881

The duration property expects a Duration as value, which has to be in the ISO 8601 duration format.

The time element can have a "valid duration string" as value (which is based on one of the ISO 8601 formats). Your value "PT4M5S" would be valid.

So you should use

<time itemprop="duration" datetime="PT4M5S">4:05</time>


Microdata parsers have to use the value of the datetime attribute, if present.

(You should use the meta element only if you can’t markup visible content.)
