Re: BRMS ( Rules ) and RDF for real life application; State of the Art?

Hi Andreas,

Thanks for your reply...
Funny as it may sound, this never occurred to me!
One has the bad habit of flying over old things... dear old Jena, so
many years by my side.

I will see if it can scale up well, if the workflow is dev friendly, etc.
I think it will all come down to the benchmarks.

There is a lot of rule management involved ( ruleset edition ), so
workflow is an important concern.

Thanks for the reminder!
