Hey #ActivityPub friends.

Hey #ActivityPub friends. Are there any new ActivityPub / Mastodon features I should add to #ActivityBot?

It's a small bot-only ActivityPub server in a single PHP file.

Terence Eden / ActivityBot · GitLab

A single PHP file which acts as a basic ActivityPub bot server.

GitLab (gitlab.com)

It can be followed, post images, allow quote posts, etc.

Is there anything else you would like a bot-server to be able to do?

@Edent Here are some that I think could be worthwhile:

FEP-c0e0 Emoji reactions (https://fediverse.codeberg.page/fep/fep/c0e0/), I think all you'd need is to accept and maybe store them
FEP-8967 Embedded link previews (https://fediverse.codeberg.page/fep/fep/8967/), would like to see adoption/progress on this
FEP-11dd: Context Ownership (https://fediverse.codeberg.page/fep/fep/11dd/), part of a push for threads that survive reply chain gaps etc.

Also https://fediverse.codeberg.page/fep/fep/8fcf/ & https://fediverse.codeberg.page/fep/fep/8b32/ for infrastructure improvements.

See anything you like?

To build on @julian@fietkau.social's bit about threadiverse...

If your blog were exposed as a Group actor and Announce'd posts by the author (a regular Person actor), then your blog could show up on NodeBB as a category, and on the threadiverse as a separate community.

@edent@mastodon.social

@julian@activitypub.space Just to note, @Edent's blog doesn't run on ActivityBot, it uses the WordPress plugin, so implementation details there are (presumably) not up for discussion here. But ActivityBot improvements would percolate to @colours, @openbenches etc.

@julian@fietkau.social ah then it should support 1b12 depending on configuration!

@Edent Not a feature, but a bug report. The ActivityPub spec doesn't spell it out super clearly, but I'm pretty sure that an Actor's Outbox should be a collection of Activities, not Objects like the single-file server uses.

So the outbox should have "type" => "Create", and the Object will specify the type it is

@samedwards Interesting. Could you point out where it says that?
(Not saying you're wrong; saying I sometimes have difficulty finding the right spec!)

@Edent https://www.w3.org/TR/activitypub/#outbox

> The outbox stream contains activities the user has published

And then an example of a Create activity on a Note https://www.w3.org/TR/activitystreams-vocabulary/#dfn-create

@samedwards got it

@samedwards Aha! Thanks.

So does this look right to you?
http://example.viii.fi/outbox

@Edent Yup, that looks like what I'd expect to see, and mirrors Mastodon as well, ie. https://mastodon.social/users/Edent/outbox?page=true

@Edent Delete and/or updating posts would be amazing. It would become a great reference implementation for basic ActivityPub interactions.

@threkk I'll have a think about how I could do that. Thanks

@Edent No, thank you for making this

It is served by an instance of your bot? The value of inReplyTo in this document is an empty string, which is not a valid URI.

@silverpill good spot!
I assume if it isn't a reply, the field should be excluded?

Or should it be something else?

@edent@mastodon.social I've learned that it should be excluded altogether, and not a null value

@julian @Edent Yep

(although I think we should bring back null)

@silverpill @julian @general
Ah, I assume that `cc` should also be null if it isn't copied to anyone?

In general, tolerance of odd values in cc is well handled, but I would just omit or send [].
