We could look at possibly to have *Lite* and *Full* versions of AS2.0.
In Lite, one could ignore even this lightweight inference but would have
less robust construct at hand. Producer would also need to stay more
explicit if they want *exactly* the same interpretation by Lite consumers.

Producer who care about same interpretation by *Lite* consumers would
need to assert "@type": ["Respond", "Like"]
If Producer accepts *slightly* different interpretation by Lite and Full
consumers. "@type": ["Like"] would only get interpreted as "@type":
["Respond", "Like"] by Full consumers, Lite would miss interred "@type":
["Respond"] - IMO reasonable consequence if someone doesn't want to
implement AS2.0 Full support.

Similar as above, the only difference comes with including details from
note core / 'external' vocabulary. Which I try to answer together with
next question.

Inputs: AS2.0 object + vocabulary definitions of *used* terms

Discovery works by simply dereferencing http(s): URI of newly
encountered term (in practice often already cached). Depending on how we
decide on AS2.0 serializations, it MUST return application/ld+json
description of the term (or the whole vocab if # pattern used, as in
AS2.0 itself), it MAY return text/turtle and text/html (RDFa). Again we
should discuss Content Negotiation sooner than later.

I want to also explore Gregg's suggestions for possible
'self-containted' options in:

Gregg, if you want to Respond to this message (or even just Like/+1)
