If, for example, you are working with large files (such as video files) this would matter.

Because if you uploaded 1GB, and the upload stopped, you would want to resume at where it stopped, and not have to upload from the beginning again.

This would be important for ActivityPub C2S adoption.

@reiver apologies for piggybacking on your ticket. 😄 🐽

I always imagined that uploadMedia was used for keeping concerns separate between object creation and media upload. Having them both present in the same place would have made more sense to me directly in an inbox/outbox.

I created an issue for it:

resumable uploads for ActivityPub · Issue #578 · w3c/activitypub

ActivityPub-based applications often allow users to upload audio, images, videos, and other file types, though most currently rely on non-ActivityPub APIs for this functionality. These files can be large — for example, a video may be sev...

Let me know if it needs more information.

It's on my to-do list for the next version of ActivityPub, so please give comments and issues!

The "uploadMedia" endpoint?

I assumed resumable uploads would be incompatible with that API endpoint.

If it isn't incompatible, could use that.

If we wanted to support resumable uploads in C2S API, then — we probably need some URL to upload the file chunks to.

…

When a user POST to their own outbox, the HTTP "201 Created" response will have a "Location" header that provides a URL.

Maybe that could be used as the upload URL.

Or, maybe the JSON-LD document at that URL might contain a URL under the "object" field that could be used as the upload URL.

Other options too

PeerTube seems to have resumable uploads already.

PeerTube seems to use this protocol for it:

I like that it uses Content-Range in the protocol. I would have done the similar.

ACK !

But also it does not look for duplicates.
If you uploaded the 1GB you would not want to upload it again (e.g. mastodon).

I am using ipfs fingerprints …
Any suggestions welcome !
