Hi Dan,

This message contains a response to comments on

http://www.w3.org/TR/2004/WD-DPF-20041122/

The draft notes the link to CC/PP, which uses RDF, as well as a very  
broad scope for the kinds of properties that might be exposed via DPF.

Examples include device configuration, people descriptions /  
preferences, locations, environmental conditions such as temperature,  
battery levels, networking infrastructure (online/offline etc).

Since so many kinds of property could be useful within DPF, I believe  
it would be good to understand a few things about the potential  
relationship(s) between DPF's property model and RDF's. Both systems  
identify properties via namespace URIs and can be applied across a  
great number of descriptive domains.

Q: Can any/all/some RDF properties be used as DPF properties?

eg. wgs84:lat="30.12" for a location, or srw:masters="fr" to express  
competence with French. These are actual RDF vocabs btw, see http:// 
f14web.com.ar/inkel/rdf/schemas/lang/index.en.html http://www.w3.org/ 
2003/01/geo/

Response:

The DPF Working Group intends addressing the integration of RDF at  
some point. However, it will not be detailed in this Working Draft  
because the DIWG is in the process of defining the CPC work items  
(link below).
