There’s no need to create and maintain separate data files for machine data or exchange (e.g., no need for separately maintained XML feeds, RSS feeds, Atom feeds, JSON, etc. Instead, if a third party wants to data or information, they just use an existing converter or write their own. It’s a standard – a lingua franca – that emerged like the original lingua franca from trade and exchange
Another relationship would be link rel = “tag” By adding rel = "tag" to a hyperlink, a page indicates that the destination of that hyperlink is an author-designated "tag" (or keyword/subject) for the current page.
Rel (relationship) tags make the content more meaningful and, therefore, make it easier to do content-specific searching. Already in use:
