Re: [tag] Proof of Concept Example of Representation

[stephen.green@systml.co.uk]

Another way to represent the test assertions using RDF might be
like that below.
Not sure about whether it's OK to use dc:identifier for TA ID or
OK to use rdf:Statement with rdf:about pointing to Spec Ref.
Not sure how to make more complex TAs this way. (May be safer to
create a special TA vocabulary instead of just using RDF's and
perhaps Dublin Cores's to make the semantics specific to TAs.)

Subject = TA Target
Predicate = name of name/value pair of what we'd call the predicate
Object = value of name/value pair of what we'd call the predicate

It should be well within scope of RDF to add qualifiers for targets
and/or to include classes and subclasses of targets, I would think.
