# Interoperability of Events in the FediverseHooray! It is now official: We have been [granted funding by NLnet](
NLnet; Interoperability of Events in the Fediverse
 ) to support the realisation [the vision we outlined in our last post](
The Work Continues: What’s Next – Event Federation
 ). > Events are at the heart of social life and deserve to be treated accordingly in the Fediverse. […] In addition, we will also investigate the Fediverse Auxiliary Service Provider Specifications (FASPs) for discoverability and filtering of public events. #FASPs #Fediverse #NGI0 #NLnet
# The Work Continues: What’s NextDetails will follow soon — but the work on events in the #Fediverse is far from complete. Key upcoming milestones include:<li><strong>Improvements and new features for the <a href="https://codeberg.org/Event-Federation/wordpress-event-bridge-for-activitypub">Event Bridge for <strong>ActivityPub</strong></a></strong> <strong>plugin for WordPress</strong><br>Continued development to maintain, fix issues, enhance, and expand functionality.</li><li><strong>Work on Fediverse Enhancement Proposals (FEPs)</strong><br>Ensuring a robust final status of FEP-8a8e and focus on recurring and irregularly scheduled events.</li><li><strong>Support for event interoperability in other Fediverse applications</strong><br>Contribute to other Fediverse applications and help them to explore and improve support for <code>Event</code> objects. For example, <a href="https://graz.social/@linos" target="_blank" rel="noreferrer noopener">@npub1pden...vh98</a> has outlined <a href="https://github.com/mastodon/mastodon/issues/20407#issuecomment-2960514632">a potential roadmap for Mastodon</a>.</li><li><strong>Contribution to GatherPress</strong><br>Active involvement in the <a href="https://gatherpress.org/">GatherPress</a> project — a modern and truly FLOSS community oriented WordPress event plugin — to ensure full ActivityPub compatibility, including RSVP support and advanced federation features.</li><li><strong>Community engagement and outreach</strong><br>Participation in conferences, public talks, and direct conversations to foster knowledge exchange, gather feedback, and grow the ecosystem around federated events.</li> 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

 ) (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:**<li>Required attributes</li><li>Events with Open End</li><li>Timezone</li><li>Physical and Virtual Locations</li><li>Event status</li><li>RSVP (Attendee Management)</li><li>Event Banner and Poster Images</li><li>Event Categories</li><li>Discoverability</li><li>Event Organizers</li><li>Upcoming Events Collection for ActivityPub actors</li><li>Term Definitions</li> Many thanks again to all reviewers and co-editors: @npub1sle6...le4v @npub1fnle...29kt @npub1cd3h...umu5 @npub16cwy...nkjm We warmly welcome further feedback from the communities of #Friendica, #Mobilizon, #Hubzilla, and other Fediverse platforms supporting events. If you’re working on such an application or are part of these communities, your insights would be very valuable! @npub1m5vh...5u0j @npub1n38p...87gn #ActivityPub #Fediverse #FEP
# Recap of CloudFest hackathonWhen you hear ‘CloudFest’, many people associate it with a business-to-business event, which it is, but the hackathon in the run-up to it still has a certain degree of community character. On the initiative of Andreas Heigl (@heiglandreas@andreas.heigl.org) and the support of Matthias Pfefferle (@npub1jwra...7v3w), [this year’s hackathon](

 ) provided the resources and space for an exchange of ideas around ‘federated events’. Our group was one of the largest and very diverse. We used the first day primarily to exchange ideas about our goals and the status quo. Afterwards, we reviewed and improved existing features and developed prototypes and concepts for new ones. For me as a developer of the WordPress plugin Event Bridge For ActivityPub, the best thing about these days was to finally get to know the entire WordPress/Automattic team involved with ActivityPub in person (greetings to @npub1mdc7...9sfl and @npub1s5mc...qjep). I would like to emphasise a few achievements in particular, without neglecting the achievements of all:<li>Matthias Heigl took the time to take an intensive look at the <a href="https://codeberg.org/fediverse/fep/pulls/430" target="_blank" rel="noreferrer noopener">FEP-8a8e</a>. His many years of experience with the development of calendar features and iCal provided important suggestions for making the specification even more far-sighted.</li><li>Laura (<a href="https://working-directory.com/" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">https://</span><span class="">working-directory.com/</span><span class="invisible"></span></a>) helped to reduce the barriers new developers face when experimenting with the interaction of Gancio/Mobilizon and WordPress and others.</li><li>Finally, many thanks to Cloudfest for the great organisation and hosting!</li> **Links:**<li><a href="https://codeberg.org/cfh25-fce">https://codeberg.org/</a><a href="https://codeberg.org/cfh25-fce" target="_blank" rel="noreferrer noopener">cfh25</a><a href="https://codeberg.org/cfh25-fce">-fce</a></li><li><a href="https://hackathon.cloudfest.com/project/federated-community-events/" target="_blank" rel="noreferrer noopener">https://hackathon.cloudfest.com</a></li><li><a href="https://fedivents.blog/">https://</a><a href="https://fedivents.blog/" target="_blank" rel="noreferrer noopener">fedivents</a><a href="https://fedivents.blog/">.blog/</a></li> #Hackathon #Fedivents #WordPress #CloudFest #CloudFest #Fedivents #Hackathon #WordPress
# Event Bridge for ActivityPub: Upcoming 1.0 ReleaseThe 1.0 release of our WordPress plugin [Event Bridge for ActivityPub](https://code.event-federation.eu/Event-Federation/wordpress-event-bridge-for-activitypub ) is scheduled for early January 2025.## Features based on evaluation resultsOver the past year, the development plan for the 1.0 release of our WordPress plugin, [Event Bridge for ActivityPub](https://code.event-federation.eu/Event-Federation/wordpress-event-bridge-for-activitypub ), has evolved significantly. After extensive testing and an evaluation process with real users, we’ve finalized the feature set for this upcoming release as follows:<li>Basic support for 10 widely-used WordPress event plugins.</li><li>Compatibility with multiple event plugins simultaneously, as we found that switching between plugins is common and maintaining archives is essential.</li><li>Event Aggregation from the Fediverse: follow other ActivityPub profiles to get and display their events. Will only be available with select event plugin integrations.</li><li>Map WordPress event categories to federated event categories, ensuring consistency across platforms.</li><li>Customizable event summaries for platforms like Mastodon that don’t natively support events in ActivityPub.</li><li>Send reminders (via <code>Announce</code> or custom <code>Note</code>) to followers at a configurable time before the event starts.</li><li>A streamlined admin dashboard that includes health checks and feedback to guide users to easily resolve faulty configurations.</li>## Security and accessibility reviewA security and accessibility review is currently taking place, and we will also be adapting the results of this. image

 ) have not yet really reached the centre of the #Fediverse. Among other things, moderation aspects play a role here (see [FEP-7458](📃.md ) or [FEP-5624](📃.md )). But in principle, they offer a wonderful opportunity to maintain consistency in discussion threads in the Fediverse. Smaller instances in particular often lack reactions to content published in the Fediverse. In principle, this is not a bad thing. Nevertheless, it makes sense for both servers and clients to be able to retrieve a complete comment tree in some scenarios (possibly at the request of a user). To this end, we have submitted a first draft in a [pull request](
