The only reason to mint resolvable URIs is to allow fetching of a description

i'd say that minting in other's people spaces is really calling for
troubles and should be discouraged? one should, could, possibly put
"sameas" if some URI exists somewhere else.

honestly? i dont even see the reasonw hy to copy this data on dogfood!
the entire point about semanti cweb is to be able to use data that's
distributed.
copying will only create wrong duplicates once you change a bit of the
data, e.g. correct the spelling of my last name in the page.

if its one source, then fine, the source is changed and its indexed
again if it has been copied.. everybody loses, i'd say :-)
