Change the Default Schema.org Microdata in Genesis

Since there are already so many great articles out there about the usefulness of adding Schema.org Microdata to your HTML5 markup, I’ll let Google help you out on that.

I encountered a situation where I needed to change all microdata for single blog posts, archive pages, home page and any other place a blog post was displayed.

Let’s get started:

When viewing a blog post there are several places that need attention, first in the <main> tag. Here, I wanted to change the itemtype from: http://schema.org/Blog to http://schema.org/CreativeWork.

With help around the web I tracked down: genesis>lib>functions>markup.php, this file outputs all the Genesis microdata. (It is helpful to open that file up and have a peek while you read this. )

The various filters in markup.php can be copied and pasted as they contain handy conditional functions to target the specific attributes I needed to change.

Here is the filter that targets the <main> tag:

add_filter( 'genesis_attr_content', 'genesis_attributes_content' );

We just have to create our own filter and function to replace the Genesis one, then paste in the conditional for Blog Microdata and customize it:

add_filter( 'genesis_attr_content', 'my_genesis_microdata_schema', 20 );

function my_genesis_microdata_schema( $attributes ){
        
	//* Blog microdata
	if ( is_singular( 'post' ) || is_archive() || is_home() || is_page_template( 'page_blog.php' ) ) {
		$attributes['itemtype']  = 'http://schema.org/CreativeWork';
		//changed from: Blog to CreativeWork
	}

	return $attributes;
        }

The next step is moving on to change the microdata in the <article> tag.

It is the next filter down in markup.php:

add_filter( 'genesis_attr_entry', 'my_genesis_attributes_entry' ); //this one is already customized

Again, copy and paste the function and modify it to suit.

function my_genesis_attributes_entry( $attributes ) {

	//* Blog posts microdata
	if ( 'post' === get_post_type() ) {

		$attributes['itemtype']  = 'http://schema.org/Article';
               //changed from BlogPosting

		//* If main query,
		if ( is_main_query() )
			$attributes['itemprop']  = 'NewsArticle';
                        //changed from blogPost

	}

	return $attributes;

}

Obviously, the attributes can be whatever is needed to suit a particular application. The combination of these two filters will change all instances of Blog, BlogPosting, and blogPost to your custom microdata anywhere a regular WordPress post is displayed.

Note: If you need to target the BODY tag use this:

add_filter( 'genesis_attr_body', 'my_genesis_attributes_content' );

Checkout Schema.org for a list of available attributes.
