Meant to say: An RDF world (circa. 2004) devoid of SPARQL and dominated by RDF/XML (rather than Turtle), is not one that many first-time visitors were *able* to comprehend or appreciate. Times have changed. In the real-world we can sign statements and/or documents using hand written signatures. We can also do so in the Web realm via RDF, in its current form, by constructing a graph that associates an RSA signature blob (denoted using http:, data:, or even di: scheme URIs) with an RDF triple and/or and RDF document. -- 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
