-- This module defines test cases for querying an RDF graph to obtain
-- a set of variable substitutions, and to apply a set of variable
-- substitutions to a query pattern to obtain a new graph.

-- It also tests some primitive graph access functions.

-- ?f father ?a, ?f father ?b, ?a /= ?b => ?a brother ?b
-- against
-- Gr3 brother La3, Gr3 brother Si3
-- should yield:
-- _:a father Gr3
-- _:a father La3
-- _:b father Gr3
-- _:b father Si3
-- (2) Perform instance query of result against 'graph2' (see above)
-- should yield:
-- _:a = Pa2
-- _:b = Pa2
-- (3) Substitute this into query, should yield:
-- Pa2 father Gr3
-- Pa2 father La3
-- Pa2 father Gr3
-- Pa2 father Si3
-- (4) Use this result in an instance query against 'graph2': it should
-- match without any variable substitutions, indicating that it is
-- a subgraph
