This is an interesting (pronounced like "frustrating") thread.

No. Mastodon is the worst offender, but the problem is that ActivityPub doesn't produce interoperability. There's no such thing as being AP compliant. That's not even a concept that makes sense. So we'd be right back here in a year or two, complaining about whatever other app ascended to popularity.

One observation I've had previously is that:

W3C creates standards to solve problems that may or may not exist in reality. They charter groups to come together and solve problems in a way that aligns with their other standards, trying to get a consensus solution to a hypothetical (or niche) problems using consensus solutions to other hypothetical problems.

You can see this in the history of RDF, then in the history of JSON-LD, then in the history of AP.

Noah Kennedy

@hrefna @jenniferplusplus that is an incredibly good way of putting it

Michael T. Bacon, Ph.D.

@jenniferplusplus

Ooft, yeah. I've been doing a bunch with RDF and JSON-LD recently in non-AP contexts, and there's a huge amount of power there but HOLY PEAS it is NOT an interoperability standard, nor could it ever be one, I think. They are ontological data format and linking standards that REQUIRE a strong defining model for interop.

I'm a fossil from the old days of the IMAP and friends IETF standards. AP is so freakin' wobbly compared to those.

Sometimes they hit on a core concern or problem, but then they keep asking "but what if" until people ignore 90% of the spec (XML I'm looking at you) and/or it gets applied to other specs that then get ignored (how many XML specs are there?). Many times the spec seems so abstract as to be unimplementable in a useful form (DIDs! you're up!)

But there's now a spec!

…that no one uses or can use. But it exists!

Specs for the sake of having specs.

@jenniferplusplus @julian discovered firsthand when working on my toy AP poster that Mastodon won't even do the "right" thing with an "image" object - instead of converting this to an embedded image in a post, it just shows it as a plain link! have to use their Attachments thing to a note activity to get that to work

Hrefna (DHC)

@noah

Heh, that's basically the thing I've been working on that I keep getting discouraged/overly frustrated by.

@jenniferplusplus @julian

Hrefna (DHC)

@MichaelTBacon

Yeah, that is one of the core points that BlueSky discussed in "why not AP":

Because if you want interoperability the RDF-isms just. don't. work. To the degree they do work, it is extremely expensive to validate and work with.

It's a model for describing things, not a model to be _understood_ about the things you are describing. That requires separate, out-of-band communication.

@jenniferplusplus I think when it comes to objects, duck typing is a good solution. Look at properties instead of types

@julian

Jenniferplusplus

@silverpill @julian it's not a strong argument for activitypub if it can't be effectively implemented in languages with compile time type checking

silverpill

@jenniferplusplus @julian My project is written in Rust and for me duck typing AP objects is not a problem. I don't have experience with other languages, but there shouldn't be any problems with them either

Sir Alecks Gates

@silverpill @julian @jenniferplusplus

Yes, it's quite easy to parse JSON in rust at compile time. There's even a package to generate a struct from a JSON schema.

Jenniferplusplus

@agates @julian @silverpill there's no schema to any of this

Sir Alecks Gates

@jenniferplusplus @julian @silverpill

So write one. Or go away

Think in a way this corresponds to trends we see everywhere.

I was pretty deep in XML working in print industry at the time, and most these standards made good sense. I got empowered with each new spec. But elsewhere vendors hyped SOA, came with super expensive "enterprise service buses" and XML a universal hammer. Until people said "Let's ditch it all".

Now we have this with cloud complexity, and e.g. people's personal websites having FAANG-like techstacks.

@jenniferplusplus I also think #ActivityPub spec seems to be designed in early 2000s where users were supposed to just trust the servers. The only way I can truly own my identity is by running my own AP server on my own domain. Content is also referred to by its URLs, not by its content-hash which makes sure that I remain dependent on other servers/intermediaries.

#Bluesky at least recognizes some of these issues.

Content being identified by IRIs (not URLs) is the backbone of the web. It could probably be other kinds of IRIs, yes, but don't drop the IRIs. And make sure they always stay dereferencable through HTTPS.

nilesh

@nik @jenniferplusplus What's this IRI you speak of?

Nik | Klampfradler 🎸🚲

@nilesh @jenniferplusplus

Basically, what you refer to as a URL (which, for the current state of the Fediverse, mostly is the same because virtually all IRIs of ActivityPub contents are URLs today).

But actually, ActivityPub content has an IRI, which does not have to be a URL, not even today: https://en.wikipedia.org/wiki/Internationalized_Resource_Identifier
