WordPress and 844e

[julian@community.nodebb.org]

Hi pfefferle@mastodon.social, I was just curious why activitypub.blog@activitypub.blog was a user and not a group on NodeBB, so I checked out its AP representation on BrowserStack.

This stood out:

  ...
  "generator": {
    "type": "Application",
    "implements": {
      "href": "https://datatracker.ietf.org/doc/html/rfc9421",
      "name": "RFC-9421: HTTP Message Signatures"
    }
  },
  ...

I thought "how would you be able to represent multiple implementations if implements is an object?

It looks like it is supposed to be an array, according to FEP 844e.

As an aside, I guess not all WP actors are groups? I feel like we've had this conversation before though hehe.

1. because the blog is in single user mode... no other actors except the blog.

2. oops!

@julian @activitypub.blog @silverpill seems to be a bug in the spec btw. https://codeberg.org/fediverse/fep/src/branch/main/fep/844e/fep-844e.md#discovery-through-an-actor

Every single value is equivalent to an array of a single value in JSON-LD... so these are equivalent:

    "implements": {
      "href": "https://datatracker.ietf.org/doc/html/rfc9421",
      "name": "RFC-9421: HTTP Message Signatures"
    }

    "implements": [{
      "href": "https://datatracker.ietf.org/doc/html/rfc9421",
      "name": "RFC-9421: HTTP Message Signatures"
    }]

So it doesn't need "to be an array", but not making it an array could trip up some clients that are not JSON-LD aware.

silverpill@mitra.social the second code example in FEP 844e is wrong though, it uses [ and ] instead of { and } around the "object" in implements
