Hey guys,


I've been working on a Peer-to-Peer application that shares metadata or 
semantics about shared resources as well as the resources themselves. Besides 
basic inference capabilities offered by platforms such as HP's JENA, I fail to 
see real value being added by Semantic Web technologies to web applications.

How far are we away from seeing a real difference being made by Semantic Web 
technologies?

I would also be interested to hear peoples opinions about the suitability of 
such technologies for ad-hoc configuration in mobile networks.


Regards,


Rory..
