[Fediverse BackUp]

Could an ActivityPub / ActivityStreams file be a "good" format for backing up a post?

(I.e., what I call an "Activity File". I.e., the file that has a media-type of "application/activity+json".)

So, I think an (ActivityPub / ActivityStreams) Activity File COULD be a "good" format for backing-up a single post on the Fediverse, but —

Most (maybe all) extant Fediverse software would need to change a bit. Fediverse software would need to support embedding "everything" in a single Activity File (rather than referring to "everything" else by URLs).

Also — what about comments / replies —

Someone people (including me) would want at least some of the comments / replies to be included in a BackUp for a post.

So, for an Activity File to be a "good" format for a BackUp, a single Activity File would also need to contain (all or selected) the comments / replies to the post.

Also — we would need to consider Threads / Storms —

Where people reply to their own post to make a larger post made up of smaller posts.

(I.e., what I have been doing here 🙂 )

For an Activity File to be a "good" format for a BackUp, a single Activity File would need to contain all the posts in the Thread / Storm.

But — for an Activity File to be a "good" format for a BackUp, there would need to be a way to get the Fediverse software to embed the (non-text) media (such as images, audio, video, etc) into an Activity File.

Now, having said that, I don't think there is anything about ActivityPub / ActivityStreams that "prevents" Fediverse software from not embedding (non-text) media (such as images, audio, video, etc) into an Activity File —

For example, an "Image" Object can contain a ("mediaType" and a) "content" field (rather than an "href" field).

But —

If you wanted to BackUp a post on the Fediverse, and all you download was the Activity File (with URLs pointing to the non-text media), then — you lost all the (non-text) media (such as images, audio, video, etc) that were part of the post.

Which would be bad.

I think one challenge, in practice, with using an Activity File as a BackUp Format is that — a lot of Fediverse software does NOT embed (non-text) media (such images, audio, video, etc) in the Activity File.

But, instead references them using URLs.

(And, by "URL" I mean "URI", "IRI", etc.)

Usually this is probably a good thing, but —

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"

Quotations & the Fediverse / ActivityPub

1/

One thing I used to do a lot on social-media is — post quotations.

Sometimes I was reading a book. And, I would quote things from the book and post it on social-media.

Or I was reading a scholarly paper, or reading a blog post, or watching a video, or listening to a podcast, etc.

...

I was thinking — how could you represent a quotation in ActivityPub‽

Apparently the Bookwyrm developer had the exact same idea!

(Which isn't too surprising.)

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"

I have spending time thinking of ways you could automatically create ActivityPub / ActivityStreams data from HTML and Markdown

Most people will probably write in plain UTF-8 text, or Markdown, or HTML

How to do you take that and get it onto the Fediverse and Social Web‽

This isn't just a question of how to technically do it — but also a question of user-experience (UX)

I.e., what are "good" ways of doing it‽
