Description

In the class org.apache.commons.rdf.rdf4j.RDF4J, there is a method

public RDF4JTerm asRDFTerm(final Value value)

Suppose that we declare a variable iri of the type org.eclipse.rdf4j.model.IRI, then asRDFTerm(iri) returns RDF4JTerm but not RDF4JIRI. To use the result as RDF4JIRI, I always need to explicitly cast.

Therefore, I would like to add three overloaded versions of this method:

• RDF4JBlankNode asRDFTerm(final org.eclipse.rdf4j.model.BNode value)
• RDF4JLiteral asRDFTerm(final org.eclipse.rdf4j.model.Literal value)
• RDF4JIRI asRDFTerm(final org.eclipse.rdf4j.model.IRI value)

So that we can avoid unnecessary casts.

There is also a similar situation in org.apache.commons.rdf.jena.JenaRDF#asRDFTerm(org.apache.jena.graph.Node)
