A few points;

- REST doesn't concern itself with "minimal set", because it doesn't
need to; the minimality of interface semantics is a consequence of their
- CRUD isn't relevant to REST except as another example of a constrained
- also, REST is much more than just what is described there, so if we want
to say "IS-A", we need to take that into account

 subset of the WWW in which AGENTS are constrained to, amoungst other
 things, exposing and using SERVICES via uniform interface semantics,
 and manipulating resources by the exchange of "representations".

BTW, that's assuming that "AGENT" is synonymous with "software
component", which appears to be the case by the arch doc (sec,
though the SERVICE definition you provided appears to disagree with it.

Good job.
