* Hi Marty,
* I don’t necessarily, but when implemented, only conditionally: “are there tags?”
* We can’t control the theme’s output (annoyingly), so this tag is omitted.
Facebook
and other OG services are aware of this and have adjusted as necessary, so the
tag isn’t required.
* There’s some heavy, technical documentation available, right here:
[https://www.w3.org/TR/rdfa-lite/](https://www.w3.org/TR/rdfa-lite/)
* Basically, this all means that Facebook comes prepared, with the ogp.me/ns dictionary,
before crawling any site and will look for the `og:...` tags accordingly.
