Re: [Bigdata-developers] Working with prefixes/namespaces

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

Alex,

I am not sure which shortcuts you are referring to.  Are you discussing the
PREFIX declarations used in SPARQL? Or the manner in which the namespaces
of the different triple or quad store instances are mapped onto URLs?

Thanks,
Bryan
