Question

Recently I have been trying to learn Semantic Web. For a project I need to retrieve data from a given dbPedia link. e.g http://dbpedia.org/page/Berlin . But when retrieve da

Note that the URI of the resource is actually http://dbpedia.org/resource/Berlin (with resource, not page). Ideally, you could request that URI with an Accept header of application/rdf+xml and get the RDF/XML representation of the resource. That's how the BBC publishes their data (e.g., see this answer), but DBpedia doesn't do that. Even if you request application/rdf+xml, you end up getting a redirect. You can see if you try with an HTTP client. E.g., using Advanced Rest Client in Chrome, we get this 303 redirect:

In a web browser, you get redirected to the page version by a 303 See Other response code. Ideally, you could request the resource URI with the accept header set to application/rdf+xml and get the data, but DBpedia doesn't place quite so nicely.

So, that means that the easiest way is to note that at the bottom of http://dbpedia.org/page/Berlin, there's the text with some download links:

RDF ( N-Triples N3/Turtle JSON XML )

The URL of the last link is http://dbpedia.org/data/Berlin.rdf. Thus, you can get the RDF/XML by changing page or resource to data, and appending .rdf to the end of the URL. It's not the most ReSTful solution, but it seems to be what's available.
