Before I had a difficult time understanding
https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format, but
with that full example of
https://www.wikidata.org/wiki/Special:EntityData/Q84.ttl in front of me,
a lot of the RDF Dump Format page is now easier for me to understand.
New question: when I see that
https://www.wikidata.org/wiki/Special:EntityData says "This page
provides a linked data interface to entity values", can you tell me what
"entity" means in the context of Wikidata? If I was going to refer to
something that can be identified with a URI and described by triples in
which it is the subject, I would just use the term "resource" as
described at
https://www.w3.org/TR/rdf11-concepts/#resources-and-statements (and
remembering what "RDF" stands for!) so I'm guessing that "entity" means
something a little more specific than that here.
Thanks,
Bob

How do I find a full statement representation? For example, what would the full
statement representation be for a triple like
{wd:Q64 wdt:P1376 wd:Q183}?
The full representation of the statement in this case is:
wds:Q64-43CCD3D6-F52E-4742-B0E3-BCA671B69D2C a wikibase:Statement,
wikibase:BestRank ;
wikibase:rank wikibase:PreferredRank ;
ps:P1376 wd:Q183 ;
prov:wasDerivedFrom wdref:ba76a7c0f885fa85b10368696ab4ac89680aa073 .
wdref:ba76a7c0f885fa85b10368696ab4ac89680aa073 a wikibase:Reference ;
pr:P248 wd:Q451546 ;
pr:P958 "Artikel 2 (1)" .
This RDF representation can be found at
<https://www.wikidata.org/wiki/Special:EntityData/Q64.ttl>. Content negotiation
will take you there from the canonical URI,
<https://www.wikidata.org/entity/Q64.ttl>
In addition to the actual value, the RDF above also give the rank, and a source
reference (nameley, the re-unification treaty).
This statement doesn't currently have a qualifier - it should have at least one,
stating since when Berlin is the Capital of Germany. That qualifier would be
represented as:
wds:Q64-43CCD3D6-F52E-4742-B0E3-BCA671B69D2C pq:P580
"1990-10-03T00:00:00Z"^^xsd:dateTime
;
The Statement ID, Q64$43CCD3D6-F52E-4742-B0E3-BCA671B69D2C, can be found in the
HTML source of the page, encoded as a CSS class. These IDs are not exposed
nicely anywhere. But usually, one would look at the RDF representation right
away, or at least got from HTML to *all* the RDF.
