DBpedia has an inclusionist model. Access to data and knowledge should be global and unified ( and free where possible) and we established this forum to further this mission.
Since we have an inclusionist model, DBpedia is huge. At the core there is data extracted from Wikipedia and Wikidata, around this there are derived datasets like the fusion/enrichment and also LHD, then there are services such as Spotlight, Lookup, SameAs and not to forget the main endpoint http://dbpedia.org/sparql and the chapters. All this is surrounded by 25k academic papers and a vivid business network.
So if you are in doubt, whether you are a DBpedian, chances are high that you are. Please suggest more categories as a reply here. We are also looking for moderators.
