Rob Atkinson commented on MARMOTTA-640:
---------------------------------------
thanks for looking into this - its the combination of LDP and simple rules
based reasoning I was keen on promoting. I can see there is OWL reasoning
available for Sesame but its not obvious there is skwrl style reasoner. Does
the kiwi reasoner require the kiwi backend or is there another skwrl style
rules based option available for sesame?
