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, claudio gutierrez, [1] C. Gutierrez, C. Hurtado, A. O. Mendelzon, "Foundations of Semantic Web databases" (to appear in PODS 04), http://www.dcc.uchile.cl/~cgutierr/papers/pods04.pdf > Related to the recent work of the RDF Data Access Working Group [1], we have > compared six proposals for RDF query languages. The report, the use case > data, and the queries are available online [2]. > > Looking forward to hearing your feedback. > > Peter Haase, Andreas Eberhart, Raphael Volz, Institute AIFB, University of > Karlsruhe > Jeen Broekstra, Vrije Universiteit Amsterdam > > > [1] http://www.w3.org/2001/sw/DataAccess/ > [2] http://www.aifb.uni-karlsruhe.de/WBS/pha/rdf-query/ >Received on Wednesday, 28 April 2004 22:10:17 UTC
