How could you represent a quotation in ActivityPub‽

...

I suppose there are 2 major approaches.

Either use an existing Object Type. Maybe:

type="Note"

Or create a new Object Type:

type="Quotation"

...

Here is the interesting thing though —

#ActivityPub #ActivityStreams #FediDev #Fediverse #ObjectTypeNote #ObjectTypeQuotation #retejo

Apparently the Bookwyrm developer had the exact same idea!

(Which isn't too surprising.)

Here is how it works —

#ActivityPub #ActivityStreams #FediDev #Fediverse #ObjectTypeNote #ObjectTypeQuotation #retejo

Object types

• Note: On services like Mastodon, Notes are the primary type of status. They contain a message body, attachments, can mention users, and be replies to statuses of any type. Within BookWyrm, Notes can only be created as direct messages or as replies to other statuses.

• Review: A review is a status in response to a book (indicated by the inReplyToBook field), which has a title, body, and numerical rating between 0 (not rated) and 5.

• Comment: A comment on a book mentions a book and has a message body.

• Quotation: A quote has a message body, an excerpt from a book, and mentions a book.

If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/reiver/statuses/115213498507317218 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
