FYI: The new article template supports not just ORCID, but also ROR markers! Your ECSCW papers can reference ROR IDs for contributing institutions and funding organizations.

Funders increasingly ask to be human- and machine-readable in papers and their metadata, @ResearchOrgs helps you with that.

@julian@activitypub.space You could also extend the leeway for Note conversion while keeping the summary length, that feels like a potentially useful option.

By that I mean letting posts with a length of n>500 (700? 1000?) through as a Note, but still cutting the summary at 500 if it's even [โ€ฆ]

@reiver @stefan You need the interaction policy as well as the ability to respond to quote requests with publicly dereferenceable quote authorizations.

If you don't care about the ability to revoke quotes, you can use a stateless blanket permission pattern that I've described here for PieFed [โ€ฆ]

@fedify That is one juicy changelog! ๐Ÿคฉ

Makes me want to jump into upgrading @encyclia, especially after we postponed the Fresh 2.x integration. But it sounds like that's going to be a bit of an adventure, so I'll wait until I can set an afternoon aside for it.

This is the biggest release in Fedify's history. Here are the highlights:

The "side effects" of an activity are everything caused by the activity other than it being visible in its actor's outbox and getting posted to its audience's inboxes. For example, a like or reply being represented in the affected object's `likes` or `replies` collection is a side effect, as is likes or replies being shown on a web page corresponding to the object.

@andypiper @reiver I've been fantasizing about a snippet library for validating and canonicalizing a fediverse (AP+WebFinger) handle. Drop in a handle/profile link/AP ID, receive full handle + web link if the input is resolvable.
