Linked Data is a method of publishing RDF data on the Web and of interlinking data between different data sources.
Linked Data on the Web can be accessed using Semantic Web browsers, just as the traditional Web of documents is accessed using HTML browsers. However, instead of blindly following nondescript links between HTML pages, Semantic Web browsers enable users to navigate between different data sources by following self-described RDF links. This allows the user to start off at one data source, and then move through a potentially endless Web of data sources connected by RDF links. It also allows the robots of Semantic Web search engines to follow these links to crawl the Semantic Web.
The DBpedia Linked Data Interface
The DBpedia data set is served as Linked Data, meaning that all DBpedia URIs are dereferenceable to RDF (and HTML as well). This allows you to access the DBpedia Linked Data Interface
- Default WWW browsers (because DBpedia provides HTML as well)
- Semantic Web browsers like DISCO, Marbles, the OpenLink Data Explorer, or the Tabulator.
- Programmatically with
curland RDF tools such as Apache Jena, Rapper, RDF4J, etc. (see here for a good list of available tools)
Access via Content Negotiation
A good overview of how Linked Data is implemented is given in this W3C document.
A brief example:
http://dbpedia.org/resource/Leipzig is the non-information URI, which will always return a
303 See Other HTTP status code giving the URI of the requested format in the
Location: response header. Note that the non-information resource is the identifier used for linking
text/turtle can be accessed via
curl -L -H "Accept: text/turtle" http://dbpedia.org/resource/Leipzig
Available formats are given in the
application/atom+xml, application/rdf+json application/odata+json application/json application/ld+json
text/n3 text/rdf+n3 application/n-triples text/turtle application/rdf+xml
URIs and Pattern
In the main DBpedia endpoint, we provide dereferencable URI for data extracted from the English Wikipedia. For each Wikipedia page, DBpedia has an entity following the same pattern:
http://en.wikipedia.org/wiki/Berlin -> http://dbpedia.org/resource/Berlin
For a full list of available URIs, you can download the latest labels artifact (select EN). The whole data dump exposed via Linked Data at http://dbpedia.org/resource/$entity can be downloaded, see the latest-core collection.
Additionally, DBpedia chapters provide similar URIs under DBpedia subdomains, see
Some example Linked Data URIs from the DBpedia data set are listed below. To start surfing the Semantic Web, please enter any of these URIs into the navigation bar of one of the Semantic Web browsers listed above.
