Greetings to the Activitypub.space community. I have a question. Is it possible to use Activitypub protocol to define a unique identity on a single account across the various federated platforms, valid for the entire Fediverse?

phi yes! It is very much possible in theory, but in practice it is less of a given.
What you're thinking of is having the "various fediverse platforms" — Mastodon, Pixelfed, WordPress, etc. — allow you to use your existing fediverse account, and for your interactions there to be done by that account, which might not be on the server you're on.
A lot of sites (this one included, for now) doesn't support that, but the base techniques are there.
We know we can achieve fediverse single sign-in through OAuth2, and the ActivityPub API can theoretically accomplish the latter. It's a matter of support, and it's something I want to focus on soon!

In practice, evan worked on a proof of concept implementation with the geotagging API.
Last I heard he had a proof of concept working, but not sure if he tested it against mariusor@metalhead.club's implementation.

julian Thanks. I think there's some confusion among the protocols for defining a single identity for the Fediverse. I've heard about the Nomad, Zot, and Streams protocols for defining a nomadic identity on Activitypub, but I'm a bit confused.

phi in that case nomadic identity a la silverpill@mitra.social would be closer.
-
@phi Initially nomadic identity was only possible in Zot and Nomad protocols, but not in ActivityPub. But we figured out how to do it in ActivityPub too.
Streams is a software that implements both Nomad and ActivityPub protocols, and supports nomadic identity. There are other projects too:https://codeberg.org/ap-next/ap-next/src/branch/main/nomadpub.md

silverpill@mitra.social I think it's important to define a feature within ActivityPub that "allows users to freely move from one server to another without losing their identities and content." Obviously, the servers don't have to be part of the same platform.

phi maybe this is a social layer problem rather than a technical problem.
Your issue means a lot in a world where we have amateur hobbyists setting up social network servers and allowing the general public to join. Those hobbyists get overwhelmed or bored after a while, or they do a bad job and your server gets defederated.
In this case, it makes a lot of sense to move from one server to another. But this is not the only way we could organize the Fediverse.
Email isn't like that. You (probably?) don't use an email address from a server you found on a list on joinemail.org. You probably, instead, have an email address from your employer or university, and maybe a personal one from a well-known and reliable cloud service. If you're very clever, you may use your own domain for email, and share it with your household or family.
In those cases, you rarely change email addresses. We have some ad hoc ways to move from one to the other, but they aren't built into the SMTP or IMAP specs. And yet we have a lot of email going around, even after 50 years.
I think we should be putting our efforts into getting Fediverse services from organizations we have a lot of affinity with, like employers or universities or the city you live in or the post office.
Another option is using the extremely portable identity system we already have -- domain names. It should be a lot easier to bring your own domain name to a Fediverse server, and to move your data between servers by backing up and restoring and then repointing your domain name to the new server, like you do for blogs. This is really hard right now.
I think LOLA is doing a good job with online moves, but we should also be encouraging more server developers to support BYOD, and we should encourage Fediverse users to get a domain.
-
evan Yes, the domain name can be an excellent solution. However I am looking for a solution where a federated platform, e.g. Mastodon, can recognize an account from another federated platform such as NodeBB or Friendica and vice versa. At the moment if I want to reply to a mastodon user, Mastodon asks me what my mastodon account is. If I give it my NodeBB or Friendica account, Mastodon rejects it. I think that the ActivityPub protocol should solve this problem.
-
phi it does, in a way! There's such a thing as the ActivityPub API, which when combined with an authentication layer would enable just such behaviour.
So far there aren't too many implementors making it happen, but it is still under development

yes they are, though? in IMAP, you can just copy your messages and folders from one inbox to another. in SMTP, we have email forwarding.
using your own DNS name can make things easier, but the main challenge in fedi is that we don't have a common storage/access abstraction (equivalent to IMAP folders), and we don't recognize HTTP redirects (equivalent to SMTP forwarding).

Has #friendica stopped including the profile image/icon in the #activitypub actor feed?
Pulled the recent stable image after a few months of things working, and it's gone.
Have I missed a setting?

@evan what's the latest with E2EE and data portability in #ActivityPub?
-
Actually I was wrong, there is a context so thats fine. The problem is that audience should be a simple string but you are sending an error, thats why it fails. Anyway that field is optional, so you can leave it out and put the community in to or cc instead.
julian No but still the field is mandatory (mainly because that hasnt caused any problems so far).

Moin,
aus aktuellem Anlaß, auf den ich später noch mit mehr Details zurückkommen will, darf ich (noch) einmal auf mein Projekt eines eigenen #Fediverse-Servers namens #Mammuthus hinweisen, in den ich demnächst mehr Zeit investieren will.
Dazu sei auch auf vier auf #Mammuthus laufende Accounts meinerseits hingewiesen, die ich in Zukunft hoffentlich auch aktiver mit sinnvollen Beiträgen bestücke... :-)
@nick@hhmx.de ⚫ Mein allgemeiner Account auf meiner als Single-Account-Instanz genutzten Umgebung, die in der Regel als erstes eine neue #Mammuthus-Version einsetzt, sobald sie aus meinem Labor kommt... ;-)
@nick@mammuthus.de ⚫ Auf diesem Account schreibe ich technische Punkte (auf Deutsch und Englisch) bezüglich #ActivityPub & Co.
@nick@rahlstedt.de ⚫ Mit rahlstedt.de, rahlstedt.biz und rahlstedt.social will ich meinen Stadtteil ins #Fediverse bringen... Details zur Entwicklung, ggf. auch Umfragen zwecks Meinungseinholung in Bezug auf meine lokalen bzw. regionalen #Hamburg-#Rahlstedt-Aktionen hier...
@nick@rahlstedt.social ⚫ Auch lokal... ein bißchen persönlicher...
Mehr demnächst...
Wem Unstimmigkeiten oder Probleme mit o.g. Accounts (und/oder den sie betreibenden Instanzen) auffallen, bitte gern an mich durchmelden. Mit Details & Co.
Notfalls an meinen #Mastodon-Account @nick@norden.social (der bleibt als Backup und langjähriger fediversaler Account natürlich bestehen).
Soweit erst einmal,
einen schönen Abend in die fediversale Runde!The Future Is Federated

nutomic oh that's interesting, does Lemmy do JSON-LD validation? I didn't think it would.
