Resource is anything that you might want to talk about. It defines the term RDF - Resource Description Framework - itself.
- New Zealand
- All humming birds in California
...are examples of resources.
Note: this can be illustrated by inference rules. Also, the examples of resources should be clickable pictures which will lead to pages about those resources (say, drawn as graphs).
Note: Triple structure (Subject, Predicate, Object) should also be drawn somewhere. I think RDF has terms for these.
Note: it is important that URI means Uniform Resource Identifier. Not Unique, because identifiers are NOT actually unique.
Note: is there a standard visualization for RDFS?
