Add support for Open Graph metadata tags as standard
Open Graph support can be added via module, but since these tags are used so frequently these days, it would be cool to have them as standard within the CMS and SiteTree objects. The basic metadata properties match up quite nicely with SiteTree fields.

Could you point to some research about how and why they are used? E.g. do search engines derive better results from them?
