The answers are:
1. false
2. true
3. false
4. true
The relevant taxonomy is
Resource
Literal
Property
Statement
In this taxonomy, the species are mutually exclusive,
but not exhaustive.
For further explanation, I'm writing up some notes on
subClassOf inferences, which will be available
tomorrow at

Subject: RDF -- venn diagram for resources, literals, properties, statements?
I am trying to understand the Venn diagram for the following sets
used in the RDF data model (http://www.w3.org/TR/1999/REC-rdf-syntax-19990222/ Section 5)
1. Resources
2. Literals
3. Properties (proper subset of resources)
4. Statements
I suspect the following are true and would appreciate either pointers to what in the spec makes them true or counter-examples:
(a) No literal is a resource
(b) No property is a statement
(c) Some statements are resources others are not.
(d) No literal is a statement
Thanks,
- Waqar Hasan
