You don't need Joseki for that, just create a static RDF file and put it on a 
webserver (http://example.com/myvocabulary.rdf), and make sure that your 
classes and properties have URIs such as 
http://example.com/myvocabulary.rdf#MyTerm. Or use a tool such as SpecGen or 
Neologism.

Right.

Gaining the trust of online customers is vital for the success of any company
that requires sensitive data to be transmitted over the Web.   Learn how to 
best implement a security strategy that keeps consumers' information secure 
and instills the confidence they need to proceed with transactions.
