Erm… concerning the `fediverse:creator` #OpenGraph tag in #Mastodon, described in :
It's either not an OpenGraph tag (which would be unfortunate), or the example in the blog is wrong.
OpenGraph, being based on #RDFa, uses the `` attribute, not `name`.
Also, if it is OpenGraph, the what namespace should I add for the `fediverse:` prefix to point to?
Which one is true for this feature, @MastodonEngineering@mastodon.social?
