Getting data from the Semantic Web. This tutorial is for programmers used to building software on top of non-Semantic-Web data sources: using screen scraping techniques, or using APIs that return XML, JSON, CSV etc. Getting data from Semantic Web sources is typically done in one of two ways: either directly getting data in an RDF serialization over HTTP or by using a SPARQL endpoint. In this tutorial, we shall get some data from DBPedia, the Semantic Web version of Wikipedia. [edit] Getting RDF data directly Some websites produce RDF data that is available in one of the many RDF serializations. The two most common RDF serializations that you need to worry about at the moment are RDF/XML and RDFa. RDF/XML is an XML format that contains RDF data while RDFa allows the developer to include RDF statements inside a web page. When you first see RDF/XML, you may find it especially hard to understand compared to 'normal' XML: often it is machine-produced and contains some unfamiliar constructs.

(Newbie note: If you have never heard of 4chan, start with the Wikipedia entry and not the website itself. The site tends to offend many adults’ sensibilities. As one of my friends put it, loving LOLcats or rickrolling as outputs is like loving a tasty hamburger; visiting 4chan is like visiting the meat factory.
At some point, it’d probably help to visit the meat factory, but that might make you go vegetarian.) Over the last year, 4chan emerged from complete obscurity to being recognized by mainstream media as something of significance. Perhaps it was moot’s appearance at the top of the TIME 100 list. More likely, it was moot’s TED talk on anonymity that tipped it all over. Amidst all of this, 4chan has “popped.” I grew up in a community of hackers at the tale end of the security hacking days. Depending on where you sit, security hackers are vilified or adored, recognized for the havoc that they wreaked and for really challenging systems to be much more secure. Mikhail Karpov.
