yeah, at a first glance, the bulk download option is a bit hidden in 
your documentation (but I guess offering bulk downloads is not your 
primary use case, or? ;) )

this is also pretty cool.

looking forward to gnd bulk request support.

Albeit, this still lefts a general question, why is HBZ doing/offering 
services that should be offered by DNB itself? ;)



PS: @Jana: in [1] is the code from HBZ guys, where a rather generic 
N-Triples to nested JSON-LD records converter is included - I guess, 
this is probably what you are looking for, or?
