title: best rdf database to quickly start a semantic web
body: <p>Hipal! I'm a newbee to semantic web. I wanna choose a RDF database which meets the <strong>Resource Description Framework</strong> and supports <strong>SPARQL</strong>.There are 4store,AllegroGraph etc. which one is better,more easier to start and has good documents(with Python in Ubuntu) for building a semantic web for Image Search. It's better to display visual graphs of a store's resources.Any guidance would be greatly appreciated.</p>
