It’s really surprising to me that the #fediverse hasn’t agreed on a standardized way to open cross-instance #activitypub objects and instead relies on links that open in the browser.

I found this proposal and what’s thinking… https://codeberg.org/fediverse/fep/src/branch/main/fep/07d7/fep-07d7.md Which one would be your favorite?
(If anyone has updates on the progress, feel free to point me in the right direction)
@ricferrer@mastodon.social the only implementor I know of who has recently played around with this is @rimu@piefed.social of Piefed. They use web intents I think, but the UX leaves much to be desired (many clicks and popups just to register the web intent)
I don't recall whether there was a SWICG task force about this topic... perhaps the HTML Discovery Task Force might be related?

Btw: matrix and xmpp seem to have well defined and well supported URIs

@ricferrer @julian @rimu We already have an URI scheme for ActivityPub objects; it's https: .

this is a serious issue Evan and dismissing it with replies like this really doesn't help anything. Its fine to not like the solution of using a custom uri scheme but currently there is not an easy way to interact with a remote object from your home server, and this is one solution to that issue that some people are already familiar with.

@wakest For good or ill, ActivityPub objects are supposed to use HTTPS URIs. It's in the spec: "Publicly facing content SHOULD use HTTPS URIs."
The discovery document shows a few good ways to discover if an HTML page, like a page loaded in a browser, represents an ActivityPub object.
One of the reasons I'm working on ActivityPub API adoption is to make this use case easier. You can see an explanation here:
Cross-server Interactions in ActivityPub
So, Richard McManus asked me about how ActivityPub supports cross-server usage. As an example use case, let's say a user with the account eric@social.example wants to comment on a photo by dionne@photos.example. In this scenario, Eric would go to the page https://photos.example/users/dionne/photos/1 and enter a comment. How would that work? I can talk about how…

@wakest Using a custom URI scheme is also going to give absolutely terrible UI for most users, who won't have an app installed.

@wakest That said, I think using the `acct:` URI scheme for Webfinger is pretty great. I've implemented a protocol handler for it here:
Unfortunately, `acct:` isn't one of the protocols allowlisted by HTML5 for linking in HTML pages, so it uses `web+acct` instead. At some point, I'll ask the HTML5 WG to add acct: to the allowlist. It's on my todo list!

@wakest there's an RFC for `acct:`

I had a quick back and forth with Gemini about the state of protocol handlers, and there are some options for getting it working without the terrible UI flow in Rimu's video (no shade to you Rimu, it was entirely out of your control!!)
Since NodeBB is installable as a PWA, it is possible to pre-register the web+ap protocol handler, in which case it should "just work" to open those types of URLs.
The other half is having a graceful fallback to opening the HTTPS URL if there is no handler... and to do that you need an interstitial page.
... aaaaand now I completely understand why those stupid "open in app/open in browser" pages exist!!! <img class="not-responsive emoji" src="https://activitypub.space/assets/plugins/nodebb-plugin-emoji/emoji/android/2639.png?v=3f6bb89c221" title="
" /> It's to trigger the protocol handler. -
@rimu@mastodon.nzoss.nz @julian @rimu@piefed.social @evan it’s a clever workaround, but what I would like to have is a possibility of reference content from the #fediverse #activitypub from any app or browser without the need to them needing to exploit support it. Also it should work independently of the client app that I am using. Just like ftp: open the right app and goes to the content.

@evan @wakest rfc 7565 describes how acct: is not resolvable, although web+acct: doesn't have this problem if you define it to use webfinger.
also i'm not sure about the browser UX but instead of a new uri scheme the typical solution here is actually content-type handlers (see firefox screenshot for example)
an http resolver SHOULD dispatch the content to the appropriate handler according to its content-type
"i'm not logged into my browser" is the issue, not "open a browser in a browser".

@evan @wakest see also https://browser.pub/ and so on
- html content goes to an html viewer
- pdf content goes to a pdf vieweractivity+json content could go to an activity viewer
-
@ricferrer @evan @julian @rimu
https: is not for web pages. it's for http resources, which can be any content type. the content should be dispatched to the appropriate content handler; for example:
- html opens in an html viewer
- pdf opens in a pdf viewer
- png opens in a png viewer
- mp4 opens in an mp4 vieweractivity+json could be opened in an activity viewer. see firefox for example in pic 1:

I understand the need to link back to an app. It’s important, but I’m voting for the open web.
All the search and discovery interactions *should* start out on a website somewhere, then link back to your home website (or possibly an app) to share and like.
But, using a new URL scheme will lock out everyone who doesn’t have an app installed, and that’s a bad UX.
Plus, I think we can solve this “back to my server” issue in other ways WITHOUT needing a URL scheme, like: #FEP3b86

@trwnh @evan @julian @rimu while this is true now, it was an evolution. As you probably know, the ht in html and http stands for HyperText, the fundamental concept that enabled websites in the early 90s
The question is what is more realistic for wide adoption… that all browsers start recognizing activities and decide if rendering in a viewer inside the browser or redirecting outside to an app makes sense.
-
@rimu@mastodon.nzoss.nz @ricferrer @julian @rimu@piefed.social @evan this is the way for web frontends, which are effectively "browsers in browsers".
if you are starting with a link in your "level 1" web browser, you need to copy it into your "level 2" web browser. https://www.devever.net/~hl/webappcoupling

@ricferrer @evan @julian @rimu any browser right now can recognize, or should be able to recognize, that the http response it got is "content-type: application/activity+json" and then open it in your system's configured activity+json processor, like a PDF or PNG or anything else.
i think it's not realistic to fork the entire namespace of http resources based on content-type. it was bad enough that https: was different from http: and we are still dealing with the repercussions of that move today
