<![CDATA[Multiple handles for Activity Intents]]>Hi @benpate@mastodon.social I've got a question about Activity Intents!

I'm implementing it now (as you noticed) and have run into an interesting issue. The wording of 3b86 suggests that the intents are distinct between users. That is, the end user inputs their handle, the handle is queried via webfinger, and supported Intents are returned.

However, the intents themselves don't really distinguish between users.

So I could have a localStorage session with multiple handles registered (e.g. julian@activitypub.space, nodebb@fosstodon.org), etc. โ€” this works fine.

But if I had two handles with the same domain, alice@example.social and bob@example.social, then my intents can't be targeted, can they... I just fire off the request (or rather, I have the end user's browser navigate) to the intent URL and whatever account is logged in will be the actor.

Did I miss something, or was there a way to distinguish actors in Activity Intents?

P.S. I find it highly amusing that you had to click through to activitypub.space to read my whole post, but because I don't support Activity Intents yet, you can't reply properly <img class="not-responsive emoji" src="https://activitypub.space/assets/plugins/nodebb-plugin-emoji/emoji/android/1f923.png?v=a8002752e25" title="๐Ÿคฃ" />

(it was a CORS issue, because the API runs under a different domain on DotCom).

You should now be able to test on activitypub.blog

They're actually two different implementations, so it might be valid to try both of them.

I'm pretty sure that @pfefferle has implemented some buttons in the WordPress plugin - Matthias, do you have a demo site we can test with?

And, I know Mastodon's Activity Intent work has landed, but I'm not familiar enough with their buttons to say which is being powered by Activity Intents, or how.

Both terms *are* in the Activity Vocabulary, so we're well within the spec to include them here. But yeah, it would be good to include a note that points to the FEPs where they're really defined.

Ok. More to do... ๐Ÿ˜…

Their association with topics and categories come from FEPs 7888 and 1b12, respectively.

However because I implement both of them, I would love both added to your FEP ๐Ÿ˜ โ€” it might mean you'll need to put a note beside each linking to their FEPs.

That makes sense. Iโ€™ve been building out contexts for conversations, so itโ€™s top of mind for me. But it makes sense that audience and inReplyTo might be enough. If the context is missing, Iโ€™d probably just fill in the context from the parent anyway.

When you reply to a topic, it's easiest to reply to a specific post, so that's why I'm using {inReplyTo}. When composing a new topic, {audience} is used to target the category.

Replying to a topic isn't really supported on the fediverse (usually you just reply to the root-level post), but it is supported in NodeBB.

Do you also use the {context} property? Should I include this as well?

NodeBB as a home server will support Object, Create, Like, Dislike, and Follow.

As a client, we have buttons for Create (topic creation and reply), Like/Dislike (upvote and downvote), and Follow.

Camper doesnโ€™t do the dialogs, though. Itโ€™s behind the scenes turning buttons on and off based on what it can find in the WebFinger results.

It might be useful to look at - and certainly feel free to steal any good ideas for your own code.

Just as well, I'd want them to look like my own dialogs anyway ๐Ÿ˜

I'll try to take a look at this tonight/tomorrow.

Once you're at a stopping point, would it be possible for you to list out the intents you publish and receive? I'd love to include that in the Implementations section at the bottom of the document.

No, I think we'd want to KISS. If you upvote something with your fediverse account, and it doesn't "show" on the site that you upvoted, I think that's ok.

The "you're exactly right" thing was an LLM joke <img class="not-responsive emoji" src="https://activitypub.space/assets/plugins/nodebb-plugin-emoji/emoji/android/1f606.png?v=0e8330245d8" title="๐Ÿ˜†" />

Okay. One-way 3b86 support is pushed to activitypub.space. Excuse the occasional broken language string, that'll get fixed up later. NodeBB will now let you register handles and can redirect to supported Like, Dislike, Create, and Follow handlers. @benpate@mastodon.social if you could give it a whirl.

The other direction, there's almost no support right now. We just expose Object intent, but I will flesh out the same intents soon, so NodeBB users can consume Activity Intents too.

I know.. agreement on the Fediverse is so rare, itโ€™s almost scary ๐Ÿ˜‰

Yeah, Undo sounds like it makes sense in your case. I didnโ€™t think of any in the beginning, so just overlooked it.

One complicating factor is in showing the โ€œstateโ€ of things in the remote site - weโ€™d need a way to know that you voted for something first, so then we could undo it.

But yeah, letโ€™s add that into 3b86 as well. What kinds of parameters would you want to pass? Or, would you just want to write a PR?
