In Schloss Dagstuhl and in Gothenburg before EDDI 2011, ontology engineers and experts from the social, behavioral and economic sciences developed an ontology of both DDI Codebook and Lifecycle and implemented a rendering of DDI instances to RDF (Resource Description Framework). The main goals associated with the design process of the DDI ontology were to reuse widely adopted and accepted ontologies like DC or SKOS and also to define meaningful relationships to the RDF Data Cube vocabulary. Now, organizations have the possibility to publish their DDI data and meta-data in RDF and link it with many other datasets from the Linked Open Data (LOD) cloud. As a consequence, a huge amount of related DDI instances can be discovered, queried, connected, and harmonized. Only the semantic combination of DDI data as well as meta-data of several organizations will enable derivations of even surprising and not imaginable implicit knowledge out of explicitly stated pieces of information.
