Re: [Virtuoso-users] Testing Graph Equality

Hello Aldo, Yes, some low-level tricks could be possible. But it depends on two things. 1) What are sizes of graphs in question? 2) With BNodes, what's the needed criterion to decide wither two BNodes are equivalent? Best Regards, Ivan Mikhailov OpenLink Software http://virtuoso.openlinksw.com

[Virtuoso-users] Testing Graph Equality

2009-10-11 Thread Aldo Bucchi
Hi, What would be a PERFORMANT way of testing graph equality for two graphs in the Quad store? * A: without BNodes * B: with BNodes I am now using SPARUL and temp graphs to generate a diff, but I imagine there is a better way ( using low level APIs perhaps? ). Regards, A -- Aldo Bucchi skype:a

FYI from: http://docs.openlinksw.com/virtuoso/sparqlbi.html in the following paragraph: When expressions occur in result sets, many variables are introduced only to pass a value from triple pattern to the result expression. This is inconvenient because many triple patterns are trivial. Big number
