Deduplication is off by default for op.fromSPARQL/op:from-sparql

In MarkLogic 11, op.fromSPARQL() 's default deduplication option is "dedup=off". In versions prior to MarkLogic 11, the default was "dedup=on". This was changed to provide optimal performance and because most use cases can tolerate duplication at the triple level. Code that previously relied on deduplication of triples when calling op.fromSPARQL() will need to change to explicitly set the "dedup=on" option in MarkLogic 11.

See De-Duplication of SPARQL Results for more details about deduplication of triples in SPARQL.
