yes, REST and RDF are orthogonal. using RDF/semweb does not solve the 
problems that REST solves, such as telling me where to go if i want to 
do things, and what i can do there. (this is where quite a bit of 
"discovery" research work has been done in the semweb community.) it 
also is the reason why i was pointing out that we should look at 
services, too, because regardless of whether egov data is exposed as XML 
or JSON or RDF or CSV, it will be important to know what services you 
can use, i.e. where to go, and how to interact with those services, such 
as how you can for example update or annotate data. and in the same way 
as you don't give the world SQL access to your relational data, my guess 
is that you won't give the world SPARQL access to your RDF data; the 
main reasons being that you want to be able to enforce constraints, 
exercise access control, control optimized access paths, and you want 
the services to be independent of implementation details.

cheers,

dret.
