Overview
RDF - Resource Description Framework.
Turtle - Terse RDF Triple Language, a common data format for storing RDF data.
SPARQL (pronounced "sparkle") - RDF query language.
The RDF data model is based on the idea of making statements about resources in the form of Subject-Predicate-Object, known as triples. These statements can be represented as a directed graph, where each Subject-Predicate-Object triple defines directed edge of the graph, StartVertex->Edge->EndVertex.
