I recently caught myself thinking about how one could implement bridges (like in Matrix), for briding “networks” that won’t support ActivityPub themselves.
Think about a web comic exposing an RSS feed for new pages. To follow it through an AP server one could implement a RSS-to-AP converter into the server.
For now the converted feed is only available internally. I then could expose it as an [email protected]. But then maybe someone else also decides to do that, using [email protected]. Nothing wrong with that I guess, but read on.
I am now thinking about a way to expose the feed without creating a proxy user.
Maybe you could implememt it in a way that allows you to say “follow mywebcomic.net/rss by using the converter myinstance.net exposes” ( or rssinstance.net)?
I would include the converters in the server metadata (like whether registrations are open), so this data can be collected by instances in the federated network.
What do you think?
