殆どのActivityPub実装では、NoteやArticleの内容（content）内で他のアクター（actor）に言及（メンション）する場合、tag属性に該当するMentionオブジェクトを含めています。では、PersonやGroupなどのアクターオブジェクトも、自己紹介（summary）内で他のアクターに言及する場合、tag属性に該当するMentionオブジェクトを含めるべきでしょうか？既にその様に動作している実装はあるでしょうか？（Mastodonは確認した結果、含めていない様です。）どの様にお考えですか？
大部分의 #ActivityPub 具顯들이 Note나 Article의 內容 (content) 안에서 누군가 다른 액터를 멘션할 境遇 tag 屬性으로 該當하는 Mention 客體들을 包含시킵니다. 그러면 Person, Group 等 액터 客體들도 略歷 (summary) 안에서 누군가 다른 액터를 멘션할 境遇 tag 屬性으로 該當하는 Mention 客體들을 包含해야 할까요? 或是 이미 그렇게 動作하는 具顯이 있을까요? (Mastodon은 確認해 본 結果 包含시키지 않는 것 같습니다만.) 어떻게 보시나요?
Most #ActivityPub implementations include Mention objects in the tag attribute when someone mentions another actor within the content of a Note or Article. Should actor objects like Person or Group also include Mention objects in their tag attribute when mentioning other actors within their bio (summary)? Are there any implementations that already work this way? (I've checked Mastodon and it seems they don't include these mentions.) What are your thoughts on this?
Just published a post about Hackers' Pub's unique username change policy! Unlike most #fediverse platforms, they allow a one-time username change while preserving your connections and content history. It's all possible thanks to some clever #ActivityPub implementation using UUID-based actor URIs instead of username-based ones. If you're interested in trying it out, the platform is currently in invitation-only beta—check the post for details on how to request access!

I'm finally unveiling the #ActivityPub project that has been consuming my weekends: Encyclia, an #ORCID bridge that will make ORCID records followable and interactable on the fediverse. 
It's early-stage and the ORCID following function is not publicly available yet. We're seeking community feedback on functionality and safety aspects. Read more at https://encyclia.pub or follow @encyclia for news!
we now have some GoToSocial docs about importing your archived posts in general: https://docs.gotosocial.org/en/latest/user_guide/importing_posts/
most of the specifics are in the slurp docs, but if you write your own importer and think it might be of general interest to GTS users, please let us know.
If you answered “No”, which installation method do you prefer?
Your feedback helps us prioritize distribution channels! Thanks for contributing to the Fedify ecosystem.
We're considering packaging the Fedify CLI for Homebrew to make installation easier on macOS and Linux (via Linuxbrew).
Fedifyの関連プロジェクトをご紹介したいと思います。ActivityPubアプリケーション開発をより簡単にするツール群です：
Fedify（@fedify）はActivityPubやその他のフェディバース標準を活用する連合型サーバーアプリケーションを構築するためのTypeScriptライブラリです。Activity Vocabularyの型安全なオブジェクト、WebFingerクライアント・サーバー、HTTP Signaturesなどを提供し、ボイラープレートコードを削減してアプリケーションロジックに集中できるようにします。
Hollo（@hollo）はFedifyで動作するお一人様用マイクロブログサーバーです。個人向けに設計されていますが、ActivityPubを通じて完全に連合化されており、フェディバース全体のユーザーと交流することができます。HolloはMastodon互換APIを実装しているため、独自のウェブインターフェースがなくても、ほとんどのMastodonクライアントと互換性があります。
Holloはまた、正式リリース前の最新Fedify機能をテストする実験場としても活用されています。
BotKit（@botkit）は私たちの最も新しいメンバーで、ActivityPubボットを作成するために特別に設計されたフレームワークです。従来のMastodonボットとは異なり、BotKitはプラットフォーム固有の制限（文字数制限など）に縛られない独立したActivityPubサーバーを作成します。
BotKitのAPIは意図的にシンプルに設計されており、単一のTypeScriptファイルで完全なボットを作成できます！
これら三つのプロジェクトはすべて@fedify-dev GitHubオーガニゼーションでオープンソースとして公開されています。それぞれ異なる目的を持っていますが、ActivityPub開発をより身近にし、フェディバースのエコシステムを拡大するという共通の目標を共有しています。
これらのプロジェクトを試してみたり、開発に貢献したりすることに興味がある場合は、以下をご覧ください：
#Fedify 자매 프로젝트들을 소개해 드리고자 합니다. #ActivityPub 애플리케이션 개발을 더 쉽게 만들어주는 관련 도구들입니다:
Fedify(@fedify)는 ActivityPub와 다른 #연합우주(#fediverse) 표준을 기반으로 연합 서버 애플리케이션을 구축하기 위한 #TypeScript 라이브러리입니다. Activity Vocabulary를 위한 타입 안전한 객체, WebFinger 클라이언트·서버, HTTP Signatures 등를 제공하여 반복적인 코드를 줄이고 애플리케이션 로직에 집중할 수 있게 해줍니다.
Hollo(@hollo)는 Fedify로 구동되는 1인 사용자용 마이크로블로깅 서버입니다. 1인 사용자를 위해 설계되었지만, ActivityPub를 통해 완전히 연합되어 연합우주 전체의 사용자들과 상호작용할 수 있습니다. Hollo는 Mastodon 호환 API를 구현하여 자체 웹 인터페이스 없이도 대부분의 Mastodon 클라이언트와 호환됩니다.
Hollo는 또한 정식 출시 전에 최신 Fedify 기능을 테스트하는 실험장으로도 활용되고 있습니다.
BotKit(@botkit)은 저희의 가장 새로운 구성원으로, ActivityPub 봇을 만들기 위해 특별히 설계된 프레임워크입니다. 전통적인 Mastodon 봇과 달리, BotKit은 플랫폼별 제한(글자 수 제한 등)에 구애받지 않는 독립적인 ActivityPub 서버를 만듭니다.
BotKit의 API는 의도적으로 단순하게 설계되어 단일 TypeScript 파일로 완전한 봇을 만들 수 있습니다!
세 프로젝트 모두 @fedify-dev GitHub 조직에서 오픈 소스로 공개되어 있습니다. 각기 다른 목적을 가지고 있지만, ActivityPub 개발을 더 접근하기 쉽게 만들고 연합우주 생태계를 확장한다는 공통된 목표를 공유합니다.
이러한 프로젝트를 사용해보거나 개발에 기여하는 데 관심이 있으시다면, 다음을 확인해보세요:
We'd like to introduce the #Fedify project family—a set of related tools that make building #ActivityPub applications more accessible:
Fedify (@fedify) is a #TypeScript library for building federated server applications powered by ActivityPub and other #fediverse standards. It provides type-safe objects for Activity Vocabulary, WebFinger client/server, HTTP Signatures, and more—eliminating boilerplate code so you can focus on your application logic.
Hollo (@hollo) is a single-user microblogging server powered by Fedify. While designed for individual users, it's fully federated through ActivityPub, allowing interaction with users across the fediverse. #Hollo implements Mastodon-compatible APIs, making it compatible with most Mastodon clients without needing its own web interface.
Hollo also serves as our testing ground for bleeding-edge Fedify features before they're officially released.
BotKit (@botkit) is our newest family member—a framework specifically designed for creating ActivityPub bots. Unlike traditional Mastodon bots, #BotKit creates standalone ActivityPub servers that aren't constrained by platform-specific limitations (like character counts).
BotKit's API is intentionally simple—you can create a complete bot in a single TypeScript file!
All three projects are open source and hosted under the @fedify-dev GitHub organization. While they serve different purposes, they share common goals: making ActivityPub development more accessible and expanding the fediverse ecosystem.
If you're interested in trying any of these projects or contributing to their development, check out:
We're excited to announce two major features coming in #Fedify 1.5.0, focused on giving you more control over domain names in your federated apps:
Separate WebFinger Host from Server Origin
Want different domains for your WebFinger handles and server URIs? Fedify 1.5.0 will let you use domains like @alice@example.com as fediverse handles while serving content from https://ap.example.com. This gives you more flexibility in how you structure your federated services.
Need to ensure consistent URLs across your infrastructure? The new canonical origin support lets you explicitly set your server's authoritative domain. This is particularly useful when running behind reverse proxies or load balancers—no more unexpected URLs generated from internal hostnames.
These features represent our ongoing commitment to making Fedify more flexible and production-ready.
Can't wait to try these features? You can experiment with them today using our unstable release v1.5.0-dev.680+562e3dc0 (JSR & npm). Keep in mind that this is an unstable release intended for testing—use it in production at your own risk.
Otherwise, stay tuned for the stable Fedify 1.5.0 release!
