[owl-s] Working example with array as parameter

[Demetris G]

Hey Jakub,

    returning back to this after a while - if this was a bug in the API 
did you
file a bug report or did anyone ever decide to fix this in the API ? I 
am sure
a lot of people would be interested in trusting transformations in grounding
and not running into a month long project like you had the unfortunate luck
to do. Any leads in how this can be fixed ?

Thanks
