Erm… concerning the `fediverse:creator` #OpenGraph tag in #Mastodon, described in <https://blog.joinmastodon.org/2024/07/highlighting-journalism-on-mastodon/>:

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 `<meta property="…">` 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?
