RDF is a Graph
- An (s,p,o) triple can be viewed as a labeled edge in a graph
- i.e., a set of RDF statements is a directed, labeled graph
- both “objects” and “subjects” are the graph nodes
- “properties” are the edges
- the formal semantics of RDF is also described using graphs
- (see the RDF Semantics document)
- One should “think” in terms of graphs, and…
- …XML or n3 syntax are only the tools for practical usage!
- the term “serialization” is often used for encoding
- RDF authoring tools usually work with graphs, too
- (XML or n3 is done “behind the scenes”)
