I think you've got the wrong email list; this list is for folks developing ActiveMQ a message broker; we don't really do RDF

Hi, I need to query all the tuples and sub-tuples who's subject is "<http://somewhere/Plants>" that essentially means fetching sub-graph behind a mentioned node in RDF. I have the following RDF Graph <?xml version='1.0' encoding='UTF-8'?> <rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#' xmlns:vCard='http://www.w3.org/2001/vcard-rdf/3.0#' xmlns:myLib='http://www.myown.org/rdf-lib#' > <rdf:Description rdf:about="http://somewhere/Fruit/";> <vCard:Type>http://somewhere/Banana/</vCard:Type> <vCard:Type>http://somewhere/Grapes/</vCard:Type> <vCard:Type>http://somewhere/Apple/</vCard:Type> </rdf:Description> <rdf:Description rdf:about="http://somewhere/Vegetable/";> <vCard:Type>http://somewhere/Potato/</vCard:Type> </rdf:Description> <rdf:Description rdf:about="http://somewhere/Plants/";> <myLib:GrowsOn>http://somewhere/Banana/</myLib:GrowsOn> <myLib:GrowsOn>http://somewhere/Grapes/</myLib:GrowsOn> <myLib:GrowsOn>http://somewhere/Apple/</myLib:GrowsOn> <myLib:SoilIn>http://somewhere/Potato/</myLib:SoilIn> </rdf:Description> <rdf:Description rdf:about="http://somewhere/Potato/";> <myLib:AvailableIn>http://somewhere/Market/</myLib:AvailableIn> </rdf:Description> <rdf:Description rdf:about="http://somewhere/Potato/";> <myLib:IsIn>http://somewhere/ShoppingCenter/</myLib:IsIn> </rdf:Description> </rdf:RDF> Apologize, if there is any error in this rdf. So, I am expecting the following tuples while ommiting the rest, <http://somewhere/Plants/> | <http://www.myown.org/rdf-lib#SoilIn> | "http://somewhere/Potato/"; <http://somewhere/Plants/> | <http://www.myown.org/rdf-lib#GrowsOn> | "http://somewhere/Apple/"; <http://somewhere/Plants/> | <http://www.myown.org/rdf-lib#GrowsOn> | "http://somewhere/Grapes/"; <http://somewhere/Plants/> | <http://www.myown.org/rdf-lib#GrowsOn> | "http://somewhere/Banana/"; <http://somewhere/Potato/> | <http://www.myown.org/rdf-lib#AvailableIn> | "http://somewhere/Market/"; <http://somewhere/Market/> | <http://www.myown.org/rdf-lib#IsIn> | "http://somewhere/ShoppingCenter/"; Can anybody plz write a SPARQL query? Thanks with appriciations. Regards, Ahmad Ali Iqbal
