Schema.org in code

Hi, why is in the code link to http://schema.org ? It’s everywhere and i don’t want to link some external sites.

Hi

This site appear in the code because contains schemes for structured data on the internet, and have an important role for SEO (and it’s recommandet by google), technically help the search engines to understand your content and display it in useful way. You can find more details here: http://schema.org/docs/gs.html Also you can remove it from the code but notice that you need to add manually all meta properties for the elements from your site.

Thanks!
