Perez2008nsparql question 3 by lebo
From Semantic Portal Wiki
A Question from Tim Lebo about perez2008nsparql:
The authors note "the occurrence of variables in the predicate position of triple patterns is forbidden in nSPARQL." This limitation resembles another that was described in the DARQ paper: "The matching compares the predicate in a triple pattern with the predicate defined for a capability and evaluated the constraint for subject and object. Because matching is based on predicates, DARQ currently only supports queries with bound predicates."
- Is there something fundamental about the need to assume a bound predicate? If so, does this inhibit the ability to make advancements throughout the field?
