I've been working on a project called openEngiadina (https://openengiadina.net/), using ActivityPub for "local knowledge".
We have an initial demo: https://openengiadina.net/geopub/
It's still very rough, but I hope enough to demonstrate how events, points of interest, local organizations and businesses can be created, shared and be discovered on the Fediverse.
A longer explanation of the demo and some background: https://inqlab.net/2020-04-06-geopub-activitypub-for-content-curation.html
This work has been supported by @NGIZero.
@charlag Thanks for the tip! Pinafore does "just work" and seems to get around CORS.
The way it works is by using the Mastodon API (https://github.com/nolanlawson/pinafore/blob/23287c6dcdb6bcdb18760c87bc4d98e1d9ca20cf/docs/Admin-Guide.md), which is set to allow CORS by default. It does not fetch content from the id of the content.
For GeoPub this is not a real solution as we would have to distinguish between content from Mastodon and the rest of the Internet.
