Publisher and Name Microdata

Question

In a BlogPosting or an Article if the publisher is a person how to use Schema.org and Microdata?

I could find that answer: Proper way to use 'publisher' in

Answer 1

That is the correct way to provide the publisher in case it’s a person.

Unfortunately, most of the time Google’s SDTT reports something as error which isn’t an error with Schema.org/Microdata, but with Google’s requirements for getting one of their rich results.

This seems to be the case here, too: it’s likely an error for the AMP version of the Articles rich result, for which Google only considers organizations (and not persons) as publishers:

publisher

Organization; required (AMP), ignored (non-AMP)

The publisher of the article.

So if the publisher is a person, simply ignore this error.

If the publisher is the same as the author, you can use both properties in the same itemprop attribute:

<div itemprop="author publisher" itemscope itemtype="http://schema.org/Person">
