[seek-kr-sms] owl-sparrow parser?

Hi,

Here is basically a stylized copy of some comments I made in the prolog 
"code" that describes the sparrow-dl operators. This is just for the OWL 
part ... and does not contain the "RDF" part, which is basically just 
defining triples of the form (subj, pred, obj), which can have a number 
of sytnaxes.

Comments greatly appreciated!
