Greeting to eveyone! New to Semantic Web. Trying to Use TDBLoader to load a
4 GB RDF/XML file.
[OS] Windows 7 - 64-bit
[Jena Version] 2.7.3
[Java Version] 1.6.0_24-b07, 64-bit
[TDBLoader Command] tdbloader.bat -loc bigRDF myRDF.xml
[TDBLoader Command Output]

Questions:
- Should I worry about the warnings? How can I get rid of the warnings?
- The following files are created under the "bigRDF" folder:
GOSP.dat GPOS.dat GSPO.dat OSP.dat OSPG.dat POS.dat POSG.dat SPO.dat
SPOG.dat journal.jrnl node2id.idn prefix2id.dat prefixIdx.dat
prefixes.dat
GOSP.idn GPOS.idn GSPO.idn OSP.idn OSPG.idn POS.idn POSG.idn SPO.idn
SPOG.idn node2id.dat nodes.dat prefix2id.idn prefixIdx.idn
stats.opt
and they are all binary. How would I query them? And where can I find
documentation about them?
