SRDFJena contains an implementation of SRDF based on Apache Jena models.

The RDFAsJenaModel class implements the different interfaces.

Example usage

import es.weso.rdf.jena._
import es.weso.rdf.nodes._
import es.weso.rdf.triples._

val ex = IRI("http://example.org/")
// ex: IRI = IRI(http://example.org/)
val schema = IRI("http://schema.org/")
// schema: IRI = IRI(http://schema.org/)

val alice = ex + "alice"
// alice: IRI = IRI(http://example.org/alice)
val knows = schema + "bob"
// knows: IRI = IRI(http://schema.org/bob)
val bob   = ex + "bob" 
// bob: IRI = IRI(http://example.org/bob) 
val t1 = RDFTriple(alice,knows,bob)
// t1: RDFTriple = RDFTriple(
//   IRI(http://example.org/alice),
//   IRI(http://schema.org/bob),
//   IRI(http://example.org/bob)
// )

val showTriples = for {
  emptyResource <- RDFAsJenaModel.empty
  _ <- emptyResource.use(rdf => for {
     newRdf <- rdf.addTriple(t1)
     _ <- newRdf.serialize("TURTLE")
    } yield ()
  )
} yield ()
// showTriples: cats.effect.IO[Unit] = FlatMap(
//   Delay(
