Dear all,
    I can not understand why syntaxes of several current rdf query languages are so much different
with the syntax of RDF data. In my opinion, a query is match a pattern(a subgraph with 
undetermined values) against the universal(the big graph in knowledge base). Why not use 
just a small rdf data set with blank nodes to represent the subgraph? 
I think these query languages have more close relation with sql than with rdf model.
