About
Dublin Core is a metadata element set used for documents and other objects.
The Open Graph protocol is a web metadata standard that defines how webpages are described as structured objects for use in social graphs and enables their consistent representation.
It specifies a set of 
HTML meta properties that start with "og:" (such as og:title, og:type, og:image, and og:description) to add semantic meaning to a page's content and control how that content should be represented.
