@hrast I've seen this passing by in #fediverse discussions many times, but always in fleety timelines.. aka lost-in-time no further #ideation lines :)

This is a good #idea to describe in more detail in the ideas inbox. Staging ground for the #FEP process and #SocialHub #ActivityPub developer community, if there are people willing to pick them up. And then in turn perhaps staging ground for further standardization by #W3C #SocialCG.

💕 I'm so thankful for all the work to the #FEP process you have 🎁 gifted this entire year. You are one of those who help the #fediverse shine, aggregating building blocks, paving pathways with grassroots #ActivityPub tiles, where only raw substrate of ✨ possibilities existed before.

This "2026 edition" I hope we can walk, all like you, in unison on a singular cause. Towards sunnier #SocialWeb futures. Grow strong to face a gloomy #SocialNetworking landscape of offline society.

FEP-0151: NodeInfo in Fediverse Software (2025 edition)

I added the "Implementations" section and a reference to FEP-844e:

https://codeberg.org/fediverse/fep/pulls/741

There are 3 independent implementations now. Since this is a "2025 edition", and 2025 is about to end, I think the FEP should be finalized.

If you have any suggestions, please comment here, on SocialHub, or create an issue.

#ActivityPub specs are basis for spec compliance.

Current fediverse is a mixture of flavors. Mastodon is a flavor. The #FEP is a recipe cookbook for particularly flavored meals.

The fedi as it is today will never offer a home to anything that does not in some way represent a timeline with flowing texts, even if masquerading in more creative UI's. Every specialist (not really, just different-than-microblogging) domain auto-excludes itself to live in the fringes of fedi. Just by being different.

Here's a draft FEP to do full account migration with posts and whatever other kinda objects you want to bring with you. It's a trivial expansion of existing ActivityPub/streams systems and supports gradual migration as it's implemented and after an account migration. It should be possible to migrate pretty much everything this way, both private and public objects.

criticism, feedback, revisions, etc. welcome - i don't think this is a "final version" and there are certainly things i overlooked.

I am a fan of starter packs on BlueSky, Threads and Mastodon's iterations on it are all for the better in my book.

My one note: i'm pretty sure from my read of it that this offering and this #FEP will be fediverse-wide and not Mastodon-only. Which makes it even cooler, if so. #fediforum

💡 Proposal for ActivityPub: FediStamp

What if any federated platform (Mastodon, WordPress, Pixelfed, PeerTube, WriteFreely...) could offer automatic certification of original content?

When publishing a poem, article, photo or video, you check "Certify original content" and the system gives you:

🔗 A public verifiable link to the registry

📄 A .fedistamp file as permanent proof

✅ A visible badge (Certified content) with clickable link

🧩 Metadata embedded in ActivityPub that travels with each share

Example: I publish a poem on Mastodon, enable the option, and instantly get my ✓ certified proof of authorship.

👉 This doesn't replace copyright (which already protects you), but strengthens it with technical evidence of authorship and date.

⚡ Key points:

Only registers the content hash (no cryptocurrency, just authorship certification).

Free.

Opt-in: you choose what to certify.

Automatic protection for creators across the federated ecosystem, without relying on centralized platforms.

I'm not a programmer, just a writer who sees the need. If someone technical sees merit and feasibility, go ahead.

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..

Also nudging to add #Bonfire as implementation in FEP docs..

SocialCG people want to make their own FEP repository on GitHub where authors will be required to sign a CLA.

I'd like to make it clear: this is not associated with the original FEP repository. The #FEP process is meant to be open to everyone, and I will do everything I can to stop any attempts to introduce CLAs there.

"Many of these [Zot/Nomad] ]ideas are being ported to ActivityPub in the form of Fediverse Enhancement Proposals (FEPs).

... Streams ... is working with Mitra to create the first implementation of nomadic identity over ActivityPub. This includes working on several related FEPs about identity proofs and conversation containers.

Our goal is for these technologies to spread throughout the fediverse."

Is anyone aware of a FEP for that?

FEP-9098: Custom emojis has been published.

#FEP #ActivityPub

Two upcoming changes in the #FEP process:

- Withdrawing stale proposals. If a proposal remains inactive for 2 years, its status is changed to WITHDRAWN. Previously, the period was 1 year after submission, and facilitators were supposed to contact authors before withdrawing (that didn't work well).
- Implementation tracking. If a proposal has type: implementation attribute, we will automatically count list items in the "Implementations" section and display that number somewhere (probably in README). If your proposal is implementable, I recommend adding type: implementation attribute to it. Also, don't forget to mention implementations if they exist - this information is very important.

@benpateBen Pate 🤘🏻 - can you post a link to that #FEP here? Is this it: https://codeberg.org/fediverse/fep/src/branch/main/fep/3b86/fep-3b86.md

FEP-844e: Capability discovery has been published to the FEP repository:

https://codeberg.org/fediverse/fep/src/branch/main/fep/844e/fep-844e.md

I already use it to signal RFC-9421 support. An anonymous Application object is added to actors:

{
  "generator": {
    "type": "Application",
    "implements": [
      {
        "name": "RFC-9421: HTTP Message Signatures",

All important information is embedded, so additional HTTP requests are not necessary.

The Work Continues: What’s Next

Details will follow soon — but the work on events in the #Fediverse is far from complete. Key upcoming milestones include:

• Improvements and new features for the Event Bridge for ActivityPub plugin for WordPress
  Continued development to maintain, fix issues, enhance, and expand functionality.
• Work on Fediverse Enhancement Proposals (FEPs)
  Ensuring a robust final status of FEP-8a8e and focus on recurring and irregularly scheduled events.
• Support for event interoperability in other Fediverse applications
  Contribute to other Fediverse applications and help them to explore and improve support for Event objects. For example, @linos@graz.social has outlined a potential roadmap for Mastodon.
• Contribution to GatherPress
  Active involvement in the GatherPress project — a modern and truly FLOSS community oriented WordPress event plugin — to ensure full ActivityPub compatibility, including RSVP support and advanced federation features.
• Community engagement and outreach
  Participation in conferences, public talks, and direct conversations to foster knowledge exchange, gather feedback, and grow the ecosystem around federated events.

Additional updates and technical details will be shared soon. Input, testing, and collaboration from interested parties are always welcome. Or if you know any conferences we should attend, let us know.

#ActivityPub #Events #Fediverse #FEP #GatherPress #WordPress

As we consider ways to implement #ActivityPub into our FOSS Community Calendar Ecosystem platform Koalagator, I've been looking over the differing specs for how to specify the event object schema.

Have any other folk wrestled with this?Asking before I get arms deep in this stuff.

For those playing at home...

---
Schema.org - Event

Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet.

https://schema.org/Event

-----
W3C Activity Vocabulary - Event

This specification describes the Activity vocabulary. It is intended to be used in the context of the ActivityStreams 2.0 format and provides a foundational vocabulary for activity structures, and specific activity types.

https://www.w3.org/TR/activitystreams-vocabulary/#dfn-event

Fediverse Enhancement Proposal
FEP-8a8e: A common approach to using the Event object type

ActivityStreams defines the Object Type Event. In real-world applications, the event object immediately showed the need for extension. Applications featuring Event objects have often chosen to add additional attributes and clarifications (i.e., interpretations) in order to implement their particular use case. This proposal clarifies and extends the ActivityPub standard to address the needs that have arisen in real-world implementations.

[HTML] Microformats - h-event

People are using microformats to mark up profiles, posts, events and other data on their personal sites, enabling developers to build applications which use this data in useful and interesting ways.

https://microformats.org/wiki/h-event

iCalendar Standard (RFC 5545)

iCalendar was first defined as a standard as RFC 2445 in 1998 by the Internet Engineering Task Force (IETF). Today, iCalendar is used to import and synchronize events on various platforms, including smart phones, computer and web applications.

#activitypub

Started writing a new FEP:

FEP-0151: NodeInfo in Fediverse Software (2025 edition)

Mentioned some best practices. What else should be added there?

#FEP #NodeInfo

After reviewing FEP-5624: Per-object reply control policies and GoToSocial's interaction policy spec, I find myself leaning toward the latter for long-term considerations, though both have merit.

FEP-5624 is admirably focused and simpler to implement, which I appreciate. However, #GoToSocial's approach seems to offer some architectural advantages:

1. The three-tier permission model (allow/require approval/deny) feels more flexible than binary allow/deny
2. Separating approval objects from interactions appears more secure against forgery
3. The explicit handling of edge cases (mentioned users, post authors) provides clearer semantics
4. The extensible framework allows for handling diverse interaction types, not just replies

I wonder if creating an #FEP that extracts GoToSocial's interaction policy design into a standalone standard might be worthwhile. It could potentially serve as a more comprehensive foundation for access control in #ActivityPub.

This is merely my initial impression though. I'd be curious to hear other developers' perspectives on these approaches.

#FEP5624 #fedidev #fediverse #replycontrol #interactionpolicy

Coda: The growth of BlueSky, and the novel features it launches with, point to a need for a 2.0 version of ActivityPub. One that fleshes out and updates the protocol based on dev experiences in the first decade of active use, and intentions going forward.

Ideally an AP 2.0 would include a formal mechanism for protocol extensions. One that learns from the experiences of the FEP process.

#ActivityPub #AP #AP2 #FEP #BlueSky

Progress on the FEP for Event objects

The FEP-8a8e (Fediverse Enhancement Proposal) had at lot of progress in the last months. In the meantime, the document has become somewhat more extensive than originally planned, but contains not only instructions for new features that have to be tediously implemented, but also a lot of advice and points that should provide orientation for developers of Fediverse applications that support events.

It now covers:

• Required attributes
• Events with Open End
• Timezone
• Physical and Virtual Locations
• Event status
• RSVP (Attendee Management)
• Event Banner and Poster Images
• Event Categories
• Discoverability
• Event Organizers
• Upcoming Events Collection for ActivityPub actors
• Term Definitions

Many thanks again to all reviewers and co-editors:

@lesionles @heiglandreasAlerta! Alerta! @naturzukunft @laurin

We warmly welcome further feedback from the communities of #Friendica, #Mobilizon, #Hubzilla, and other Fediverse platforms supporting events.

How to subscribe to a thread?

Several days ago FEP-efda: Followable objects was published. I don't like this solution because ActivityPub spec only talks about "following" in the context of actors, and the proposed "proxy-following" mechanism forces us to change some well-established practices.

So here is an alternative: FEP-f06f: Object observers.

Object observer is an actor that can be followed to receive object updates. If conversation thread is a collection, its observer will broadcast Add and Remove activities that have thread collection as their target. Observer's followers will have an up-to-date view of the thread.

#ActivityPub #FEP

I've made some changes to FEP-521a: https://codeberg.org/fediverse/fep/pulls/482

- Many changes due to a rename of Controller Documents specification to Controlled Identifiers.
- Using https://www.w3.org/ns/cid/v1 context in example. I haven't tried it myself yet, but it works in JSON-LD playground.
- Key ID and actor ID are now recommended to have same origin.
