I suspect, historically, folks have stayed away from expressing this important association due to the amount of triples it generates. <#SomeGraphIRI> :contains <#SomeStamentIRI> . <#SomeStatementIRI> a rdf:Statement; rdf:subject <#SomeStatementSubjectIRI>; rdf:predicate <#SomeStatementPredicateIRI>; rdf:object <#SomeStatementObjectIRI>. Statement reification is useful. We are now getting to the point where real-world issues are bringing its utility to the fore :-) -- Regards, Kingsley Idehen Founder & CEO OpenLink Software Company Web: http://www.openlinksw.com Personal Weblog: http://www.openlinksw.com/blog/~kidehen Twitter/Identi.ca handle: @kidehen Google+ Profile: https://plus.google.com/112399767740508618350/about LinkedIn Profile: http://www.linkedin.com/in/kidehen
