tdbloader2 named graphs

Hi all,

I’m trying to use tdbloader2 to import multiple ttl files into DB.

I want (the triples from) certain files to go to certain named graphs, but I don’t know how to specify that – it all goes to the default graph.

Does anybody know?

Regards,
Stefan

    And while converting, if you go TTL -> N-Quads you can load a bit 
    faster. To do the prefixes, just have a file with only prefixes and add 
    it to the files to load.
    
    tdb2.tdbloader does support --graph but only one setting per load.
    
    There is only so much that can be sensibly done from a command line 
    tool.  The next step up would be to add some kind of manifest processing.

Best to do that.
