Dear RDF WG, I've reviewed the SPARQL 1.1 Entailment Regimes. It is very good in my opinion and there are very little details that have an impact on RDF, methinks. I will provide my personal review to the SPARQL WG soon. However, I noticed one point that could be of interest to the RDF WG: In Section 4 "D-Entailment Regime", it is said: "A datatype map for the D-entailment regime MUST contain at least all pairs of the form <prefix:dt, dt>, for which prefix:dt is one of the entries from the table below ..." here, dt is a placeholder for xsd or rdf. This means that all datatype maps MUST include the XSDs. Note that this is not the case in RDF Semantics. The RDF semantics only mentions XSD as an example of datatype map, but implementations are free to ignore part or all of them. Should we update D-entailment such that it necessary supports XSDs? (my answer: yes) Regards, -- Antoine Zimmermann Researcher at: Laboratoire d'InfoRmatique en Image et Systèmes d'information Database Group 7 Avenue Jean Capelle 69621 Villeurbanne Cedex France Tel: +33(0)4 72 43 61 74 - Fax: +33(0)4 72 43 87 13 Lecturer at: Institut National des Sciences Appliquées de Lyon 20 Avenue Albert Einstein 69621 Villeurbanne Cedex France antoine.zimmermann@insa-lyon.fr http://zimmer.aprilfoolsreview.com/
