How can I add the Schema.org type 'BreadcrumbList'? I want to add the Schema.org type BreadcrumbList for my website. 

I have installed Schema.org module, but I'm unable to find any option there. 

I tried using the Easy Breadcrumbs module, but it does not have the Schema.org type BreadcrumbList. 

I have checked on the Schema.org website and there in example given for JSON-LD.
function yourtheme_breadcrumb($variables) {
  $sep = ' &amp;gt; ';
  if (count($variables['breadcrumb']) &gt; 0) {
    return implode($sep, $variables['breadcrumb']);
  }
  else {
    return t("Home");
  }
}
