------------------------------------------

Github user ghxiao commented on the issue:

    https://github.com/apache/commons-rdf/pull/31
  
    I added  a test case`RDF4JMethodOverloadsTest` and one more method in RDF4J
    
    `public RDF4JBlankNodeOrIRI asRDFTerm(final org.eclipse.rdf4j.model.Resource value)`

> 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)
