*Really* not meaning to jump down any http-range-14 rabbit holes but
wasn't there a plan for wikidata to have uris representing things and
pages about those things?
From conversations on this list I sketched a picture a
while back of all
the planned URIs:
Was the "thing" uri (which you could point a foaf:PrimaryTopic at) and
Was the document uri
Mainly asking not for the wikipedia > wikidata relationships but wondering
if there's a more up to date picture of supported wikidata uri patterns
Recently I was trying to find a way to programmatically get wikidata uris
from wikipedia uris and tried various combinations of:
(all mentioned on the list / wiki) but all of them return a 404
Is the a way to do this?

How about using RDFa and foaf:primaryTopic like
in this example

The FOAF options were designed for relations between entities and
foaf:primaryTopic relates a Document to a thing that the doc is
primarily about (i.e. assumes entity IDs as value, pedantically).
the inverse, foaf:isPrimaryTopicOf, was designed to allow an entity
description in a random page to anchor itself against well known
pages. In particular we had Wikipedia in mind.
(Both of these share a classic Semantic Web pickyness about
distinguishing things from pages about those things).
Much more recently at schema.org
we've added a new
property/relationship called http://schema.org/sameAs
It relates an entity to a reference page (e.g. wikipedia) that can be
used as a kind of proxy identifier for the real world thing that it
describes. Not to be confused with owl:sameAs which is for saying
"here are two ways of identifying the exact same real world entity".
None of these are a perfect fit for a relationship between a random
Web page and a reference page. But maybe close enough?
Both FOAF and schema.org
are essentially dictionaries of
hopefully-useful terms, so you can use them in HTML head, or body,
according to taste, policy, tooling etc. And you can choose a syntax
(microdata, rdfa, json-ld etc.).
I'd recommend using the new schema.org
'sameAs', .e.g. in rdfa lite,
This technically says "the thing we're describing in the current
element is Buckingham_Palace. If you want to be more explicit and say
"this Web page is about a real world Place and that place is
Buckingham_Palace ... you can do this too with a bit more nesting; the
HTML body might be a better place for it.
