vSPARQL
Contents:
Overview:
vSparQL is an extension
  of the W3C recommended query language for RDF, SparQL, with additional syntax enabling the creation of
  application ontologies as views of reference ontologies.
  Specifically, our extension adds support for
  subqueries, recursive queries, and Skolem functions
for the creation of new nodes.
