If you are looking for a user tool to import an RDF file into BrightstarDB, you should use Polaris. It is installed with BrightstarDB if you use the full Windows installer (you can get it from
http://brightstardb.codeplex.com/). You can then use Polaris to create a BrightstarDB store and import RDF into it. A variety of formats are supported including RDF/XML and NTriples. There is full documentation about Polaris at
https://brightstardb.readthedocs.org/en/latest/Using_Polaris/, but if you need any help please just ask!
