Knowledge graphs

DBpedia

DBpedia (.org) is a community effort to enable the web moving "Towards a Public Data Infrastructure for a Large, Multilingual, Semantic Knowledge Graph".

Today the DBpedia data sets contain a wealth of information structured into ontologies. This structured data can be queried with SPARQL query language at their public DBpedia SPARQL endpoint.

There are many methods how the DBpedia ontology and datasets could be used in the Consumerium implementation stage wiki. One of these would be to install the LinkedWiki extension.
