Re: A Comparison of RDF Query Languages

Motivated by this interesting report, we want to call your attention to a
study in many ways complementary: a study from a theoretical point of view
of a basic core of RDF query languages. The paper [1] presents a formal
study of the "conjunctive" fragment of RDF query languages, as well as a
first approach to normalization of RDF data. Same as the report, feedback
is very welcomed,
