I’ve been trying to execute some SPARQL on Virtuoso, and one persistent problem I have is knowing what will work with the edition of Virtuoso I have (in my case, the package
virtuoso-opensource-6.1 as available in the current version of Ubuntu 20.04 repositories, but note that this question is more general).
Is there any clear list of what each edition of Virtuoso will support? Specifically, can I expect all of SPARQL 1.0? How about 1.1? If not all, which parts should I avoid?
So far I’ve found very little on a quite lengthy search of various forums and the virtuoso documentation. What I have found suggests that existing versions of Virtuoso support some, but maybe not all 1.1 features. Unfortunately the version of Virtuoso required is never specified in the cases I have seen.
