Package org.aksw.jenax.io.rdf.json

Interface JsonProvider

Type Parameters:
K - The key type of objects. The type correspondences are strings for JSON and RDF terms for RON.
V - The type of values contained in literals. Typically object for JSON and RDF term for RON. If we allowed a V type, then we'd need a Java-to-V mapper, such as Object-to-Node.
All Known Implementing Classes:
JsonProviderOverJsonPath
public interface JsonProvider
Abstraction akin to JSONPath's JsonProvidere. There are subtle differences between JSON and RON: In RON, keys and literals are all RDF terms.
