@tetron @jenniferplusplus this basically means that not only does your schema have to account for extensions (especially "required extensions" in the case of how fedi uses the `publicKey` property), you also have to be clear about semantics at some level. either that is done via the mime type, via the context declaration, or perhaps via some schema that indirectly embeds or references something equivalent to a context (as is being proposed at the top of this thread).
