Schema information about resources in the Linked Open Data (LOD) cloud can be provided in a twofold way: it can be explicitly defined by attaching RDF types to the resources. ...
Based on these observations, we derive conclusions about the design of future schemas for LOD as well as potential application scenarios. ...
