Ed and other respondents, (01)
I prefer to look at the entity relationship semantics on the Web as
being akin to screen resolution fidelity. You have high and low
resolution. There are data spaces within the Linked Open Data cloud
where the fidelity or entity relationship semantics are very high and
discernible to humans and machines. Of course, there are enclaves where
the aforementioned semantic fidelity is very low. Such is the nature of
the Web. (02)
The Web's ultimately advantage is that crowd-sourcing is intrinsic. The
number of subject matter experts contributing to the Linked Data Cloud
is growing rapidly too :-) (03)
