    @kopper @hongminhee @cwebber and to know other people being really happy with JSON-LD and really needing this functionality, you need to get out of your own application context and into data flows. E.g. Trade transparency. And they may also use activity pub at some point:

    @rigo @hongminhee @cwebber i'm sorry but this conversation is drifting towards a very unrealistic "why aren't game items NFTs so you can move your items between games" view of the world that ignores a significant chunk of real world forces, including user experience (do people even want what you're after?), in order to promote a specific technology

    i can't see how this discussion can produce anything useful when that's the lens you're looking at things from.

      @kopper @hongminhee @cwebber but the JSON parser will not recognize naming conflicts. We are talking about data flows beyond the application context. I see you arguing in a social-media distributed twitter context and not a millimeter beyond. That's ok

      Inside that context, JSON-LD remains valid JSON and your implementation can ignore the context. But as soon as you want to annotate stuff and NOT hardcode it into your app, this context becomes important.

      namespaces! explicit namespaces! the property name https://w.on-t.work/ns#content does not conflict in any way with https://www.w3.org/ns/activitystreams#content! please stop talking in circles, we're all tired i think

        @kopper @hongminhee @cwebber Oh, I see what you mean. We had that (very heated) discussion in 2004 between the RDF folks and the XML folks. You're using JSON like the XML argumentation back then. And yes, it is possible to re-invent RDF functionality using JSON or XML. This was the point of the 2004 dispute. JSON-LD is only ONE way to solve those possible conflicts. It just happens to be an interoperability specification we call "recommendation".

        Sorry for my misunderstanding on namespaces.

          Hi! 👋🏼 Nice to meet you. I'm well aware of `sharedInbox` and helped design it.

          Realtime is an illusion. You can make it pretty convincing.

          Your users are mostly not online. Remote users are mostly not online. Tracking the last time remote and local users were seen can help you prioritize local and remote delivery.

          It's a lot better to deliver to the tiny percent of users currently online first rather than delivering to the user named `aaaaaaaaamng` first.

          @evan@cosocial.ca Can I say something, as someone who is not technical but cares deeply about the fediverse and its future, and who read the whole conversation with great interest?

          You might be familiar with the term "desire path". It's when a place, like a park, has pre-designed pathways, but people end up using their own, because they are more convenient. This is not user error - it's a design failure.

          I've been hearing complaints about JSON-LD since I was in Firefish. When so many people -including even people who co-wrote ActivityPub!- tell you that it's problematic, that it has ended up not being used, that most projects find their own shortcuts (or desire paths) and we need to find a better way, telling them "you should just use it as it was designed" comes off as arrogant and short-sighted. And these are not people who work for BlueSky or people who want to see fedi fail - they are people who care so much about ActivityPub that they have studied it and built whole applications around it. It's not nice to dismiss them like that.

          You have co-written and are largely responsible for something that was meant to be used by people and developers. Clearly, its core is great, or it wouldn't have been relatively successful. But if parts of it were too complicated and have not been adopted, then it's a design problem with these parts. A good protocol should be easy to work with and build on.

          I don't think you should be scared of breaking backwards compatibility. This is sometimes an essential part of progress - and if something doesn't progress, it usually dies. For how long will people keep building on a protocol that stays stagnant to not break backwards compatibility? Ten years? Twenty? Yes, you don't want to make big changes very often. But
          never making big changes also doesn't make much sense. Especially regarding parts that are not used as intended in practice, therefore have proven to have failed. Accept it and find collective ways to improve ActivityPub, or blame everyone else for not following to the letter a spec that obviously doesn't fit well with their needs.

            Anyway, to me, a backwards-incompatible change is absolutely the worst possible choice we could make for the Fediverse. It splits the network, possibly permanently. We have about 100 implementations of ActivityPub, and they can't all upgrade at the same time.

            I do note that you argue for backwards "Fediverse-compatibility" here, and I wonder how that equates with backwards #ActivityPub compatibiity.

              ah, no - that is a misunderstanding!

              Anyone can feel free to represent the texts only and the user at least "knows" it.
              But the thing for Public Broadcasters means 47mio. users in DE alone and given the unified codebase for the 5 projects _these_ softwares will interpret it.
              It does JSON-LD you could just check by asking for any JSON-LD e.g. Q1055 (Hamburg) - it is content-negotiation.
              The taxiteam software is funded by the German yellow cabs - the official ones (!) the codename is FCKUBR 😉 and I have no doubt about adoption fortunately.

              Maybe we can work out better examples …

              addendum;
              updated the hierarchical UNESCO World Heritage Collection with their 1247 Entry-Collections having 8000 Places.

              Apart from `Content-Negotiation`
              Noticed that you can also get the jsonld in the browser just by adding ".json" e.g.

              https://www.wikidata.org/wiki/Special:EntityData/Q122842228.json
