Hi, Chris's recent question prompted me to send this message. RDF datasets and named graphs aren't a difficult concept.
However, I do not know why, every time something "unexpected" happens in relation to named graphs or SPARQL queries involving FROM/FROM NAMED I need to go back to the documentation: - http://www.w3.org/TR/sparql11-query/#rdfDataset - http://openjena.org/ARQ/Tutorial/datasets.html - http://openjena.org/wiki/TDB/Datasets - http://openjena.org/wiki/TDB/DynamicDatasets - http://openjena.org/wiki/Fuseki#Service_3 I also have a small dataset which I use to test my queries. I done this over and over... is it only me having this sort of cognitive disorder specific to named graphs and ARQ|TDB|Fuseki? :-) Paolo
