hello cory.

i think that distinction is at the core of many discussions around the 
narrow or the wide interpretation of what linked data is. i have always 
thought of myself to work on linked data, but some assume i don't, 
because i am not following the RDF approach.

nope. the web tells you to link resources, to link resources in a way 
that uses a uniform interface, and to expect to interact with resources 
through that interface in a way that allows you to inspect them and then 
follow links found in them, to interact with more resources. you can use 
whatever representation you like, as long as you make representations of 
resources available in self-describing hyperlinked ways. semweb 
introduces more constraints on representations (RDF is the only 
acceptable metamodel), and removes the uniform interface constraint.so 
you end up with a style that makes it easier to seamlessly follow the 
linked graph, because there is only one metamodel, but you cannot as 
easily have non-read interactions with resources, because there is less 
granularity in the model, and there is no uniform interface.

cheers,

dret.
