Comment on Why is Pixelfed an extra network and not just a Mastodon client?

It is not. A server that “speaks” the ActivityPub is not that difficult to build, I’ve done it. The complexity is in getting the data from the social graph into and creating a good UX for users who are too used with the “app-centric” mentality.

I’m still not sure I quite get it. Like, Bookwyrm has to have all of those books for me to create a message that embeds the book I’m reading. Without knowledge of all of the books that one might read, I can’t select the one I want to read? Or are all of the books objects stored on activitypub and I get the data from the social graph itself? Does the subject-verb-predicate structure of json-ld allow for embedding the full complexity of data that not only represents the social graph, but also everything else you might want to reference?
Also, thanks for the link. Looks like the docs are also a reasonable reference on Activitypub as well as being for your server.

Not “stored on activitypub”, but each book could be represented with RDF (it could be something as sophisticated as using DublinCore or as simple as just using isbns to uniquely identity the books (
urn:isbn:1234556789) , and then each activity for “CombatWombatEsq read a book” would be an activity where you are the actor and the book is the object.CombatWombatEsq@lemmy.world 1 week ago
Right, but I don’t want to enter the isbn to say that I’m reading a book, I want to search by title or author. Once you achieve any kind of scale, whoever your client is scraping to get the book data for those kinds of queries is going to block you; practically speaking you need to keep an index of books on your server to allow people to discover the books that are available? Clients have pretty limited abilities in practice, because there aren’t a lot of services that vend well-curated data for free.

You know that the whole of wikidata can be copied with just a few hundreds of GBs, right? There are plenty of examples of community-driven data providers (especially in the *arr space), so I can bet that there would be more people setting up RDF data servers (which is mostly read-heavy, public data sharing) than people willing to set up their Mastodon/Lemmy/GoToSocial server - because that involves replicating data from everyone else, dealing with network partitions, etc…
Also, there are countless ways to make this less dependent on any big server, the client could pull specific subsets of the data and cache data locally so the more they are used the less they would need to fetch remote resources.
Think of it like this: a client-first application that understands linked data would be no different than a traditional web browser, but the only different is that the client would only use json-ld and not HTML.
