Hi everyone, While testing history in the graph I’ve run into occasional stack overflow when adding the Jena Model to the triplestore using an UpdateRequest. Initially I was using Syntax.syntaxSPARQL_11 (the default for UpdateFactory) but after googling a bit I found http://thread.gmane.org/gmane.comp.apache.jena.user/8195 which makes me think it is an inherent issue with the SPARQL 1.1 syntax parser and large updates. Per the recommendation in 8195 I moved to using Syntax.syntaxARQ which through initial testing seems to have eliminated the stack overflow. The javadoc for syntaxARQ simply states it is *The query syntax for extended SPARQL* which doesn’t really tell me a lot. Does anyone know the difference between syntaxSPARQL_11 vs syntaxARQ?
Thanks Neda
