Re: Web service in WSDL vs. "service" in OWL-S

Xuan,
	you are reading way too much into this, and making incorrect  
interpretations.  When we wrote the original documentation, it was  
not talking about web sites - you keep banging on about this but the  
position you're arguing isn't an accurate representation of what was  
written.

There are a number of different views regarding what constitutes Web  
Services, and what is a web service (should it be in XML?  Must it  
have its interface defined in WSDL?  What if a service grounds its  
interface in WSDL, but communicates directly with its peers using a  
KQML binding, and thus doesn't use http or xml at all???).   
Personally I don't want to get involved in that discussion, just as  
after several years of hearing similar debates about what is an  
autonomous agent ("oh, is it a light-sensitive switch?", for example).

Finally, could you please cease firing questions in a rather  
aggressive manner at certain individuals?  This is a large community  
that has been researching this field for a long time now, with all  
varying points of view (which make discussions interesting).   
However, with these recent questions, its started to feel more like a  
court of law (i.e. why this, why that, you said this, but you meant  
that, and its wrong).  If you have questions, then read the  
*research* literature and put the pieces together as others have done.
