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.

Apparently, Bookwyrm stores quotations with:

type="Quotation"

And if one Bookwyrm server talks to another Bookwyrm server, then — the ActivityPub / ActivityStreams representation of the quotation will have:

type="Quotation"

...

BUT — if a non-Bookwyrm server talks to a Bookwyrm server, then — the ActivityPub / ActivityStreams representation of the quotation will have:

type="Note"

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

If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/reiver/statuses/115213501304803057 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
