Hi Tomas,
I'm really not an RDF processing expert, but since nobody responded for 4
days, I'll try to give you some pointers:
I know that there've been discussions regarding RDF processing on this
mailing list before.
Check out this one for example:

Good afternoon,
Currently we are using UnifiedViews (unifiedviews.eu) for RDF data
processing. So you may define various RDF data processing tasks in
UnifiedViews, e.g.: 1) extract data from certain SPARQL endpoint A, 2)
extract data from certain folder and convert it to RDF, 3) merge RDF data
