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.
