But you don’t need the AT protocol and lexicons to describe semantics. Ontologies have been a thing for decades, and search engines (the “rich results”) and ActivityPub use them.

Why use the lexicons you described, instead of the more supported https://www.w3.org/ns/activitystreams ontology that ActivityPub uses, for example?

If you allow me to, I would be interested in re-writing your article but by using ActivityPub concepts instead. Maybe I will learn about a fatal flaw in one of the protocols during that process.
