RDF database?

[wei xing <xing@ucy.ac.cy>]

Dear all,

I am now trying to develop a RDF-based Grid information system. So far I
have defined a RDF Grid Schema, and have some sampled Gridbench RDF
files in RDF-XML using the Schema.
  
Could someone kindly recommend me a database system suited to store and
query these RDF data? 

I would really appreciate any feedback!

With Regard

Wei
 
PS: Gridbench is a benchmarking software developed by our group within
EU Crossgrid project.
