I certainly agree with Thomas that examples used throughout the RDF* documents
and discussions are ill-supported by the various formal definitions underlying
RDF*.
We see
:bob foaf:name "Bob" .
<<:bob foaf:age 23>>
dct:creator <http://example.com/crawlers#c1> ;
dct:source <http://example.net/listing.html> .
in http://ceur-ws.org/Vol-1912/paper12.pdf
<<:painting :height 32.1>>
:unit :cm;
:measurementTechnique :laserScanning;
:measuredOn "2020-02-11"^^xsd:date.
<<:man :hasSpouse :woman>>
:source :TheNationalEnquirer;

What should be concluded from this? Just about the most charitable conclusion
is that RDF* is unsuitable for its claimed use.
So what is RDF* good for? I am concerned about this.
