Hi, I have created an original joomla blogpost and wanted to style this so i inspected the css on my page. I can see the following link to a schema.org site on every blogpost i have in the page. Is this correct - is it supposed to be a part of the code? I dont understand what this is used for?

<div class="article" itemprop="blogPost" itemscope="" itemtype="schema.org/BlogPosting">
