   What is the “DBpedia Snapshot” Release?

Historically, this release has been associated with many names: "DBpedia Core", "EN DBpedia", and — most confusingly — just "DBpedia". In fact, it is a combination of —


   EN Wikipedia data— A small, but very useful, subset (~ 1 Billion
   triples or 14%) of the whole DBpedia extraction
   theDBpedia Information Extraction Framework
   <https://github.com/dbpedia/extraction-framework>(DIEF), comprising
   structured information extracted from the English Wikipedia plus
   some enrichments from other Wikipedia language editions, notably
   multilingual abstracts in ar, ca, cs, de, el, eo, es, eu, fr, ga,
   id, it, ja, ko, nl, pl, pt, sv, uk, ru, zh.


   Links— 62 million community-contributed cross-references and
   owl:sameAs links to other linked data sets on the Linked Open Data
   (LOD) Cloud that allow to effectively find and retrieve further
   information from the largest, decentral, change-sensitive knowledge
   graph on earth that has formed around DBpedia since 2007.


   Community extensions— Community-contributed extensions such as
   additional ontologies and taxonomies.
