Nucleus for the Web of Data
The Web is currently changing from a medium to publish and share text documents into a medium to publish and share data.
This transition is facilitated by ideas from the Semantic Web community and initiatives like the W3C Linking Open Data project.
As DBpedia covers many domains and provides data-backed identifiers for 3.64 million concepts, it is developing into an interlinking-hub for other data sets.
Please see Interlinking for an overview about the data sets that are currently interlinked with DBpedia and W3C Linking Open Data for a list of other data sets and ontologies that are published on the Web as Linked Data.
