When web spiders crawl sites they take on account semantic HTML to extract data to help search engines, but sometimes they need more info
To tackle this problem Google, Microsoft, Yahoo and Yandex founded Schema.org to provide consistent information (microdata) for spiders as HTML attributes
I made a pull request with the microdata for events, but I will suggest to add it for the rest of the content of our site, e.g. blog articles, study cases, etc.
