In the spirit of expanding this example,
https://www.wikidata.org/wiki/Q5597 is the wikidata URI for
http://viaf.org/viaf/64055977/

As well as all sort of wikimedia-specific information (such as links to
encyclopedia articles in many languages, links to wikisource digital
copies of textual works by and about them and their name translated into
many languages), it contains asserts such as: their VIAF identifier
(plus many other identifiers), sex, dates of birth and death, places of
birth and death, occupations, etc. etc.

As a person implementing an RDF system, I'm not going to look at every
assertion and decide whether or not to import it into my core system,
I'm going to look at wide classes of assertions.

I might decide that the wikidata definition of sex is not one I'm happy
with and exclude that, for all people.

I might decide that I don't care about wikisource digital copies (which
are reachable via wikipedia anyway) and exclude those for all people.

I might decide that I only care about locally-relevant languages plus
the standard UN set, and exclude all the other labels.

I'm definitely going to decide that I'm going to exclude unattributed
notes that someone smelled badly.

This is conceptually no different to importing a large batch of MARC
records and looking at the various note and private fields and deciding
which to include and which to exclude.
