Hi, All:
When I run a TDBLoader (came with Jena 2.10.1), I got a warning
WARN riot :: {W137} Input is large. Switching off
checking for illegal reuse of rdf:ID's.
- How do I switch off rdfLID checking? I looking into "TDBLoader --help"
but couldn't find any clue.
There is some kind of RDF/XML option. tdbloader does not expose it;
you'd need code to set it.
- I suppose the whole loading would be faster if I switch it off, correct?
Maybe but unlikely. The cost of loading is usually raw XML parsing +
loading (which don't play well together).
You must be at some degree of scale to the the warning.
My recommendation is parse the RDF/XML to N-triples so that it is
completely checked, then load the NT.
Loading N-triples is faster than RDF/XML (the parser slows the loader
down!).
With a file of any size, checking it first, so the load does not break
half-way through, is usually a good idea to incorporate in a workflow.

Thanks a lot for all your help!
