Re: (Part 1) Where did these syntax constraints come from?

Let me make comments similar to those that Pat has made, but somewhat (!)

RDF has no semantics.  It never has had a semantics.  I say this even
though Richard and Deborah have produced the beginnings of a semantics for
RDF.  Their effort only provides semantics for the portion of RDF
that has a fairly obvious meaning.  (It does not provide a complete
semantics for containers or for reification.)

As with any syntactic system without a clear semantics, people using RDF
have had fights over what various RDF constructs are supposed to mean.   I
forsee these fights continuing ad nauseum.

DAML+OIL uses only a fraction of RDF.  It (purposely) does not use the RDF
constructs that are most open to misinterpretation.  Nevertheless, DAML+OIL
is on somewhat shakey grounds even with this restriction to the
more-obvious portions of RDF.
