For all of the use cases in POWDER UCR
http://www.w3.org/TR/2007/NOTE-powder-use-cases-20071031/
I think that special purpose POWDER software is needed.

However, the more that POWDER builds on other recommendations, in a 
manner that is fully compliant with those recommendations, the more 
likely it is that such special purpose POWDER software can be built 
cheaply, effectively and correctly.

To the extent that POWDER deviates from the formal semantics of RDF 
and/or OWL, there is a danger that POWDER software implementors will end 
up fighting tools that conform with such semantics, as opposed to using 
them.

However, from the point of view of the POWDER WG and users this is a 
'shades of grey' issue, rather than a black-and-white conform or not.
Minor deviations from the RDF and OWL semantics, while not something *I* 
would want to encourage, are unlikely to be too costly to the POWDER 
community.
