Portability of extension-specific activities or content? #14

Open bumblefudge opened 4 months ago

bumblefudge commented 4 months ago

On today's TF kickoff call, Aaron G brought up an interesting point-- migrating between a server that supports lots of extensions/FEP-specific Activities (with, say, custom properties defined in a supplemental @Context file), to a more "bare bones" server that does just the standard minimum, what happens with those Activities? Do they create a Collection called "IdunnoWhatTheseAre"? Are they silently dropped, or displayed with a warning that contents may be more rich than they appear? It might be worth adding a section (at least a non-normative warning under "Interoperability Considerations"?) that states assumptions.

A relatively easy example: https://codeberg.org/fediverse/fep/src/branch/main/fep/5624/fep-5624.md
