@pfefferle if I'd come up with a scheme for them they would be related to pairs of activityType:objectType entries (instead of a global write), or maybe just the activityType
GoActivityPub doesn't really do "scopes" because I couldn't think of a way store the permissions on the server side in a way that doesn't require custom logic to interact with vanilla ActivityPub objects.
I started using a service called Concert Archives (it is what it sounds like) and I really like it! It’s helped me remember live shows that I had forgotten I even went to and artists I didn’t even recall seeing until looking at the archive entries. I wish it was federated with #ActivityPub, something like that on the fediverse would be very cool. Here’s my profile (still working on adding concerts, lots more to go…) https://www.concertarchives.org/jonathan-rollans#Music #Live #Concert
