So in wikidata dump you will find mappings between sitelinks and QIDs.
A sitelink it is a wikipedia link . for example:
http://en.wikipedia.org/wiki/Obama.
That particular example redirects to another sitelink:
http://en.wikipedia.org/wiki/Barack_Obama (this is the canonical for this
topics/entity)
The mapping from wikipedia sitelinks to QIDs you get on wikidata does not
assure canonical sitelink.
So you can have a mapping telling you that Q123 is linked to "Obama".
However Spotlight would in principle never return "Obama" but its canonical
identifier "Barack_Obama"
