Sorry, not sure what you mean.
No URIs are minted on sameAs (other than the implied search ones).

I think the answer to this is that we are simply serving URIs, and any
descriptions come from resolution.

The sources are quite wide, but actually as I recall, I have not used
Sindice at all to generate the data.
Sindice provides a similar service by using the query Giovanni published,
but over different data (and perhaps with different service packaging), and
so it didn't seem worth duplicating that (I avoid duplicating things without
adding value).
The answers will of course be different - what I am aiming for is a more
controlled view, compared with the looser sindice view.
(Of course we are still vulnerable to errors, and I do know of some.)
The sources are very varied, from rdf dumps to SPARQL queries to files
provided by publishers.

I think I used openlinksw to provide some of the data, but I'm not sure
what. I think it may have been stuff involving skos:{closeMatch,exactMatch}

Fundamentally we began gathering this data for our purposes to use in the
RKBExplorer stuff, and so it seemed a useful thing to do to make it
available.
