This might be a stupid question, but… why are we getting those counts from
the page props in the first place? Special:EntityData already has to load the
full entity data, so I don’t think we’re saving much work by getting those
numbers from the `page_props` table. And using `page_props` not only means that
the RDF for the latest revision might have statement counters that are slightly
out of date – it also means that the RDF for earlier revisions contains
counters that are just totally unrelated to that revision. For instance:
$ curl -s
https://www.wikidata.org/wiki/Special:EntityData/Q42.ttl?revision=112 | grep
-A2 wikibase:statements
wikibase:statements "248"^^xsd:integer ;
wikibase:identifiers "183"^^xsd:integer ;
wikibase:sitelinks "113"^^xsd:integer .
If you look at Q42?oldid=112 <https://www.wikidata.org/wiki/Q42?oldid=112>,
you can see that it did not actually contain over two hundred statements –
which is understandable, since that revision predates support for statements on
Wikidata by several months. (Maybe this mismatch was already reported
somewhere, but I didn’t find any relevant Phabricator task other than this one.)
