> to support the proliferation of RDF, I have begun work on a tool to convert
> RDF data into relational databases. It is intended for people who want to use
> data available only as RDF but do not have the patience to install a triple
> store and learn SPARQL. I know there are tools that present a SQL view
> over a triple store but installing such an environment also is quite 
> challenging.

> 
> My tool works much like the one described in this paper (has it ever been 
> implemented ?), with important differences:
> 
> -It supports incremental runs (adding more RDF data to a database later)
> 
> -It supports entailment (rdfs:subClassOf, rdfs:subPropertyOf, rdfs:domain, 
> rdfs:range, owl:equivalentClass, owl:equivalentProperty,
> owl:FunctionalProperty)
> 
> The software is written in Python and uses the RDFLib Python library. It works
> with local and remote files. You can find more information and download it at
