One thing that feeds offer is a machine-readable rights declaration. Here is a copy/paste from my feed: <rights>All content written by Tim Bray and photos by Tim Bray Copyright Tim Bray, some rights reserved, see /ongoing/misc/Copyright</rights> - the linked HTML file asserts invokes a CC license.
Does ActivityPub have the equivalent?
Because for legal issues, I’m really uncomfortable relying on defaults. These things should be explicit.
