RDF Graph Model
We propose a new formal model for representing any set of RDF triples as mathematical graphs.
Example
Triple | Subject | Predicate | Object |
---|---|---|---|
T1 | BobDylan | isMarriedTo | SaraLownds |
T2 | BarackObama | isMarriedTo | MichelleObama |
T3 | isMarriedTo | rdfs:subPropertyOf | isSpouseOf |
T4 | BobDylan | isSpouseOf | SaraLownds |
T5 | BarackObama | isSpouseOf | MichelleObama |
For the set of RDF triples in the table above, we explain how each approach represents them in the graph.
The NLAN model
The BI model
The LDM model
More complex examples
Singleton_Property approach to representing
