[jira] [Resolved] (CLEREZZA-865) VirtuosoMGraph does not serialize bnodes correctly in internal queries

Enrico Daga resolved CLEREZZA-865.
----------------------------------

    Resolution: Fixed

This should be now solved. The solution was to use skolemization of bnodes - a Virtuoso specific method to point to bnodes. This is the only way to keep consistency between bnodes within the lifecycle of a single VirtuosoMGraph instance. Without this, different calls to .filter(s,p,o) on the same graph using shared bnode instances would not be consistent.

> For this reason performFilter throws an exception when a bnode that is returned by a previous read operation is then used as parameter of a new read.
