Re: [Bigdata-developers] Problems with RDR

[Bryan T. <br...@sy...>]

Max,

What deployment mode are you using? Do you have the log from startup where
it lists out the registered RDF parser factories? Openrdf needs to be
before The Blazegraph jar on the class path or the RDR parsers will get
unregistered by openrdf. See http://trac.bigdata.com/ticket/1060.  We hope
to address this issue in 1.5.2.

Thanks,
Bryan
