I am a newbie, trying to learn about RDF, RDFa and stuffs related to it since few days..
My question is, consider following HTML + RDFa code .. is it possible to extract the RDF part separately? if so could you please demonstrate simple code snippet (PHP or Java)..
i have heard Jena could be used, but couldn't find a tutorial which explains this. So if it is possible with Jena could anyone post some code snippet please..
