I’m wondering if there are any common or standard approaches to modeling RSS feeds as ActivityPub objects?

I’m thinking of an RSSFeed actor and RSSPost or something for the items but I’d love to follow established patterns.

Friendica supports RSS feeds. Maybe that’s a good place to start?

#ActivityPub

The two big features in release v3.2.7 of Ktistec are back end support for creating polls (the front end is coming in the next release) and advanced theming support—specifically, a rich vocabulary of CSS class values and data attributes on which to build a theme. The full set is documented in the README. I'll post more on how I'm using these later this week.

Here is the full set of notable changes:

Added

• Back-end support for creating polls.
• Advanced theming support with new classes, data attributes, and view helpers.
• Task status display on admin page showing running and imminently scheduled task counts.

Fixed

• Poll vote form now correctly submits Question ID.

Changed

• Move location of Ktistec version notice. (fixes #133)
• Updated admin page for better accessibility and less clutter.

sometimes i wish #activitypub and servers/clients supported both Like and Love activities, for when liking something  isn't strong enough...!

I took a detour and worked on alt text editing in release v3.2.6 rather than continuing with the polls backend. I also continued to fix bugs and to add polish. Here's the full set of changes:

Added

• Support for editing alt text in the Trix editor. (fixes #52)

Fixed

• Render fallback icon when actor is down.
• Remove blank figcaption elements.
• Emojify display names in notifications.

Changed

• Color notifications label by type of unread notifications.
• Render lines instead of points for server starts in metrics.

(I'm editing this post in Markdown—the new feature in the last release!)

I rolled out a lot of features over the last several weeks and created a lot of bugs in the process. Release v3.2.5 of Ktistec is mostly about fixing those bugs. I did implement two requested features, however: support for editing posts in Markdown and support for Open Graph metadata. Here's the full list of new features:

Added

• Support for editing posts in Markdown. (fixes #25)
• Support for Open Graph metadata on actors and objects. (fixes #71)
• Support for uploading a site image.
• Internal table of contents page.
• Poll expiry notifications.

🎄 I'm working on support for poll creation and management now. It's also time for a performance improvement pass or two.

I wonder if you could use/abuse Mastodon polls (FEP-9967) to distribute posts that provide near-real-time status updates (I'm thinking about severe weather alerts but I'm sure there are other use cases)?

Create a poll with an expiry far in the future and a token set of options (ideally just one—"Do you opt in?"—but poll implementations seem to require at least two).

Nothing seems to prevent the content of a poll from changing—and this is the key insight. The FEP says, "The type of a poll (single choice / multiple choices) and its options might be changed at any time. In that case the author of the poll MUST reset the vote counts." So broadcast updates via the content.

It would be a lightweight way to follow a single item without following the actor, built on top of implementations that already exist. 

#ActivityPub #Fep9967

The big feature in release v3.2.4 of Ktistec is support for viewing and voting on Mastodon polls (AKA FEP-9967: Polls). This feature took a surprising amount of work. Some of the effort was due to my struggles with visual design, but getting the behavior right was also tricky. For example, a "vote" is just an ActivityPub Note, but unlike other notes, it shouldn't appear in a poll's replies (it could, but that would be redundant and confusing). So I had to add exceptions throughout the code to deal with this. A custom Vote object type would have been nice in the original implementation.

Added

• Support for viewing and voting on polls. (fixes #49)
• Added tooltip to notifications menu item summarizing new notifications.

Fixed

• Improved wrapping of actor panel follow/refresh information. (fixes #130)
• Autocomplete now works correctly when adjacent to a Trix attachment.
• Image title attributes are now preserved.

Changed

• Moved avatars to the bottom of the object detail view.

Thank you @jayvii for the build fix!

#ktistec #crystallang #activitypub #fediverse

Release v3.2.3 of Ktistec includes two big features:

• FEP-1b12 Group federation
  Improved federation with Lemmy and other forum-type servers. Ktistec supports community and thread follow/unfollow, as well as up-vote/like (down-vote/dislike is supported but there is no visual affordance for that yet).
• FEP-9098 Custom emojis
  Support for viewing custom emoji in posts and on actor profiles. Ktistec does not yet support custom emoji creation and management.

The full changelog:

Added

• Support for viewing custom emoji in posts and on actor profiles.
• Actor type (Person, Group, etc.) overlay badges on actor panels.
• Colored fallback avatars for actors without icons.
• Support for robots.txt.

Fixed

• Federation with Lemmy and other servers that support FEP-1b12.
  • Shared inbox support for local actors.
  • Serialization of Undo includes the undone activity.
  • Serialization of Like and Dislike does not.
• Notify only once for an object's first received activity.

Changed

• Accumulate metrics by hour for finer granularity.
• Clean up presentation of public followers/following pages.

The next release will include support for Mastodon polls (FEP-9967).
