Nola erantzun WordPressetik Mastodoneko mezu bati
Tut honi erantzunez: Instalatu ActivityPub plugina. Horrek ActivityPub protokoloa erantsiko dio zure blogari eta, praktikan, fedibertsoko beste instantzia bat bilakatuko du, Mastodonekin zein fedibertsoko beste edozein sarerekin zuzenean komunikatzeko ahalmena emanez. Egin oinarrizko konfigurazioa: aukeratu zure blogak fedibertsoan erabiltzaile bakar bat edo bat baino gehiago izan behar duen, profil orriak editatu, erabaki zer bidalketa mota federatuko diren eta zeintzuk ez... Zalantzarik […]https://teknopata.eus/2025/10/nola-erantzun-wordpress-mastodon-activitypub/

... subject for a FediForum session. We are non-partisan with respect to protocols, and want the entire open social web to succeed. And as it is an unconference, the discussion can branch out over several sessions if needed if an action plan were to emerge! #AtProto #ActivityPub

"How can ActivityPub and AtProto join hands so both can fight the Romans rather than each other?"
Now here's a question! That makes a great subject for a FediForum session. We are non-partisan with respect to protocols, and want the entire open social web to succeed. And as it is an unconference, the discussion can branch out over several sessions if needed if an action plan were to emerge!

I'm trying to decide how much of "quote posts" I want to support in Ktistec. On one hand, it's not trivial functionality, and I really do question how much extra value someone's comments on someone else's post will add to the Fediverse. On the other hand, I dunno... assuming Mastodon limits abuse by enforcing quoting rules, Ktistec could probably just follow along and display quoted posts. Is there any value in just that?

Bluesky was never an alternative. I don't say it isn't better than Twitter; it is. However, the only genuine alternative, as of now, remains the Fediverse and Mastodon.
And most people won't admit it because they're too lazy to go through the "server browser" procedure, which is literally two clicks.
We put no effort into things and expect better/different results? That's silly.

Getting started with Mastodon's Quote Posts - technical implementation details for servers
Quoting posts on Mastodon is slightly complex. Because of the privacy conscious nature of the platform and its users, reposting isn't merely a case of sharing a URl.
A user writes a status. The user can choose to make their statuses quotable or not. What happens when a quoter quotes that post?
I've read through the specification and tried to simplify it. Quoting is a multi-step process:
- The status must opt-in to being shared.
- The quoter quotes the status.
- The quoter's server sends a request to the status's server.
- The status's server sends an accept message back to the quoter's server.
- When other servers see the quote, they check with the status's server to see if it is allowed.
I'm going to walk you through each stage as best as I understand them.
Opting In
An ActivityPub status message is JSON. In order to opt-in, it needs this additional field.
"interactionPolicy": { "canQuote": { "automaticApproval": "https://www.w3.org/ns/activitystreams#Public" }}That tells ActivityPub clients that anyone is allowed to quote this post. It is also possible to say that only specific users, or only followers, or no-one is allowed.
The QuoteRequest
Someone has hit the quote post button, typed their own message, and shared their wisdom. Their server sends the following message to the server which hosts the quoted status. This has been edited for brevity.
{ "@context": [ "https://www.w3.org/ns/activitystreams", { "QuoteRequest": "https://w3id.org/fep/044f#QuoteRequest", } ], "type": "QuoteRequest", "id": "https://mastodon.test/users/Edent/quote_requests/1234-5678-9101", "actor": "https://mastodon.test/users/Edent", "object": "https://example.com/posts/987654321.json", "instrument": { "id": "https://mastodon.test/users/Edent/statuses/123456789", "url": "https://mastodon.test/@Edent/123456789", "attributedTo": "https://mastodon.test/users/Edent", }, "quote": "https://example.com/posts/987654321.json", "_misskey_quote": "https://example.com/posts/987654321.json", "quoteUri": "https://example.com/posts/987654321.json" }}All this says is "I would like permission to quote you."
The Stamp
The quoted server needs to approve this quote. First, it generates a "stamp".
This is a file which lives on the quoted server. It is proof that the quote is allowed. If it is deleted, the quote permission is revoked. The filename must be the same as the stamp's ID.
{ "@context": [ "https://www.w3.org/ns/activitystreams", { "gts": "https://gotosocial.org/ns#", "QuoteAuthorization": { "@id": "https://w3id.org/fep/044f#QuoteAuthorization", "@type": "@id" }, "interactingObject": { "@id": "gts:interactingObject" }, "interactionTarget": { "@id": "gts:interactionTarget" } } ], "type": "QuoteAuthorization", "id": "https://example.com/quote-987654321.json", "attributedTo": "https://example.com/users/username", "interactionTarget": "https://example.com/posts/987654321.json" "interactingObject": "https://mastodon.test/users/Edent/statuses/123456789",}If the quoted status is viewed from a different server, that server will query the stamp to make sure the share is allowed.
The Accept
This is the message that the quoted server sends to the quoting server. It references the request and the stamp.
{ "@context": [ "https://www.w3.org/ns/activitystreams", { "QuoteRequest": "https://w3id.org/fep/044f#QuoteRequest" } ], "type": "Accept", "to": "https://mastodon.test/users/Edent", "id": "https://example.com/posts/987654321.json", "actor": "https://example.com/account", "object": { "type": "QuoteRequest", "id": "https://mastodon.test/users/Edent/quote_requests/1234-5678-9101", "actor": "https://mastodon.test/users/Edent", "instrument": "https://mastodon.test/users/Edent/statuses/123456789" "object": "https://example.com/posts/987654321.json", }, "result": "https://example.com/quote-987654321.json"}The "result" must be the same as the stamp's URl.
And then?
You can follow and quote @colours@colours.bots.edent.tel on your favourite Fediverse platform.
I've written an ActivityPub server in a single file which is designed to teach you have the protocol works. Have a play with ActivityBot.

@cadusilva @marte Estive refletindo sobre o ECA Digital desde ontem. Pessoal usando linguajar mais "forte" ou qualquer conteúdo impróprio para mais jovens também deveria usar #CW.
Vislumbro que algo que pode vir a ser desenvolvido para facilitar a adequação do #ActivityPub à nova lei brasileira e que também está surgindo em outros países é que os clientes, p.ex. navegador, não exiba conteúdo marcado com CW. #W3C poderia recomendar essa solução.

What I loved to see in the #ActivityPub documentation is the inclusion of the list of Fediverse Enhancement Proposals #FEP's that are implemented. It will serve a stimulus for other #fediverse devs to adopt them too, and shape the grassroots standardization process. Posted the list to #SocialHub too..
https://socialhub.activitypub.rocks/t/bonfire-social-1-0rc3-is-released/8071
Also nudging to add #Bonfire as implementation in FEP docs..
