The DBpedia dataset describes 2,180,000 “things”, including at least 80,000 persons, 293,000 places, 62,000 music albums, and 36,000 films. It contains 489,000 links to images, 2,700,000 links to relevant external web pages, 2,101,000 external links into other RDF datasets, 207,000 Wikipedia categories, and 75,000 YAGO categories.

Each of the 2.18 million resources described in the DBpedia dataset is identified by a URI reference of the form http://dbpedia.org/resource/Name, where Name is taken from the URL of the source Wikipedia article, which has the form http://en.wikipedia.org/wiki/Name. Thus, each resource is tied directly to an English-language Wikipedia article.
Every DBpedia resource is described by a label, a short and long English abstract, a link to the corresponding Wikipedia page, and a link to an image depicting the thing (if available).
If a thing exists in multiple language versions of Wikipedia, then short and long abstracts within these languages and links to the different language Wikipedia pages are added to the description. The DBpedia dataset contains the following numbers of abstracts per language:

Wikipedia Categories are represented using the SKOS vocabulary.
The YAGO Classification is derived from the Wikipedia category system using Word Net. Please refer to Yago: A Core of Semantic Knowledge – Unifying WordNet and Wikipedia for more details.
Word Net Synset Links were generated by manually relating Wikipedia infobox templates and Word Net synsets, and adding a corresponding link to each thing that uses a specific template. In theory, this classification should be more precise then the Wikipedia category system.

Using these classifications within SPARQL queries allows you to select things of a certain type.

The DBpedia dataset contains 22.8 million pieces of information that have been extracted from infoboxes within the English version of Wikipedia. The types of the infobox properties depend on the type of the infobox, and there are approximately 8000 different property types. Many infobox property values are typed using XML datatypes.

The DBpedia dataset contains HTML links to external web pages as well as RDF links into external data sources.
There are two types of links to HTML pages: dbpedia:reference links point to several web pages about a thing. In addition, some things also have foaf:homepage links that point to web pages that can be considered the “official homepage” of a thing.
RDF links are represented using the owl:sameAs property. Please refer to Interlinking for more information about RDF links and the interlinked datasets.
