Note that while Open Graph recommends specifying the “og” RDFa Core 1.1 CURIE prefix mapping via, no such markup is required for Twitter cards and its use of the twitter: prefix in a HTML meta element’s name attribute. This allows for both to be defined on the page independently, and minimizes the amount of duplicate markup required to describe content and experience. When the Twitter card processor looks for tags on a page, it first checks for the Twitter-specific property, and if not present, falls back to the supported Open Graph property. When using Open Graph protocol to describe data on a page, it is easy to generate a Twitter card without duplicating tags and data. Twitter card tags look similar to Open Graph tags, and are based on the same conventions as the Open Graph protocol.
